HotPDF Napomene o izdanju

Version 2.748.6

Fixed

• Popravljeno je predenje kroz ceo deklarisani broj unosa kod cross-reference podsekcije koja deklariše više unosa nego što tabela sadrži, iako za čitanje više nema podataka, pa je odbacivanje neispravne datoteke od četrdeset bajtova trajalo desetine sekundi
• Popravljeno je gubljenje svih već dobijenih rezultata kod job runnera kada operacija izbaci grešku, i gubljenje picture objekta pri HTML uvozu kada stream oko njega nije mogao da se napravi

Version 2.748.5

Fixed

• Popravljeno je otvaranje PKCS#12 datoteka sa lozinkom van ASCII: lozinka je UTF-8 niz bajtova, ali se širila bajt po bajt umesto da se dekoduje, pa je izvedeni ključ bio pogrešan za svaki znak van ASCII. Datoteke zaštićene modernom PBES2 šemom nisu bile zahvaćene, pa se zato ta dva različno ponašala
• Popravljeno je podizanje access violationa umesto sopstvene greške kod signature batch validatora i revocation evidence cache-a kada se naprave sa neispravnom opcijom, pošto se destruktor izvršavao pre nego što su napravljeni članovi koje oslobađa
• Popravljeno je padanje evidence download zadatka u destruktoru kada su njegovi argumenti odbijeni, pošto su provere išle pre nego što je sama nit bila napravljena
• Popravljeno je kodovanje algorithm identifiera kod cloud-signature providera kada drugi luk prelazi 39, a neispravan identifikator sada podiže providerovu sopstvenu grešku umesto greške konverzije
• Kontejneri sertifikata i potpisa sada odbijaju ugnježdeni element koji deklariše dužinu koja prelazi element koji ga sadrži, pa ono što se validira i ono što potpis pokriva više ne mogu da se razlikuju
• Vrednosti privatnog ključa se posle RSA potpisivanja brišu iz memorije umesto da ostanu na heapu za sledeću alokaciju

Version 2.748.4

Fixed

• Popravljeno je učitavanje Type 1 fontova koje je svako svojstvo čitalo iz prvog reda font programa: token lista je dopunjavana bez pražnjenja, pa su version, family i weight stringovi, stem hints i charstring key length uzimani iz zastarelih tokena. Type 1 fontovi sada prijavljuju svoje metapodatke
• Popravljeno je čuvanje charstring key length kao pokazivača u string koji je već oslobođen i korišćenje bez provere opsega; sada se čuva kao vrednost i ograničava na opseg koji format dozvoljava
• Popravljeno je vraćanje neugrađenih fontova uvek na sistemski podrazumevani font: traženo ime fonta je kopirano u wide-character font zapis bajt po bajt, pa se nijedna instalirana familija nikada nije poklapala
• Popravljeno je čitanje prekraja isečenog font programa kod parsiranja ugrađenih TrueType i OpenType fontova dok se dekoduju glyph outlines, argumenti composite glyph-ova i CFF tabela OpenType kontejnera, a neispravna character map više ne traži negativan glyph niz
• Popravljeno je prekoračenje deklarisanih brojeva objekata kod cross-reference tabela i streamova: unos koji tvrdi broj blizu limita integera prebacio se u negativan indeks i upisivan je van tabele, a deklarisani broj objekata ili /Size mnogo veći nego što datoteka može da sadrži dimenzionisao je loader-ove nizove samo na osnovu te tvrdnje

Version 2.748.3

Fixed

• Popravljeno je odbijanje ispravnog unosa kod Data Matrix: veličina simbola se procenjivala prepolovljenjem broja cifara, ali code word dele samo susedne cifre, pa je tekst poput 1a2a3a birao simbol premalen za sopstvene podatke i enkodovanje je padalo
• Popravljeno je dekodovanje četvorobajtnih UTF-8 znakova u XFDF-u, poput emodžija, u pogrešan surrogate par, a neprepoznat bajt više ne proguta tri znaka koja slede
• Enhanced-metafile region zapisi sada ograničavaju broj pravougaonika veličinom zapisa umesto da veruju broju u region headeru, koji je mogao da čita daleko preko zapisa
• PNG slike čija deklarisana širina puta visina premašuje adresibilni opseg odbijaju se već u headeru umesto alokacije pixel bafera negativne dužine
• High-quality image resampling sada prijavljuje zahtev van opsega umesto prekoračenja veličine svog međubufera
• WebP meta prefix slika koja tvrdi više entropy grupa nego što ima piksela odbija se umesto da od par stotina bajtova ulaza alocira stotine megabajta prefix tabela
• Popravljena su curenja na failure putevima Aztec enkodovanja, WebP bitmap dekodovanja i object-stream decode worker poola, gde je pri padu kasnijeg koraka ostavljen delimično napravljen objekat

Version 2.748.2

Fixed

• Popravljeno je gubljenje poslednjih bitova code worda kod QR Code simbola: obilazak rasporeda modula preskočio je krajnju levu kolonu, pa rep poslednjeg error correction bloka nikada nije upisan u simbol
• Popravljeno je punjenje celog ostatka data bloka nula bitovima od strane QR terminatora, pa nije ostalo mesta za 0xEC / 0x11 pad code words koje zahteva ISO/IEC 18004; simbol verzije 1 je umesto toga nosio šest nula code wordova
• Novi test čita generisani simbol nazad iz njegovih modula, pa se data blok, pad code words, error correction blok, maska i raspored proveravaju protiv standarda, a ne protiv sopstvenog izlaza encodera

Version 2.748.1

Fixed

• Popravljeno je zapinjanje tri parsera na neispravnom ulazu umesto prijave: object parser na >> unutar niza ili ] unutar rečnika, CMap reader na zalutalu zagradu ili vitičastu zagradu i XFDF reader na konstrukciju bez tag imena (na primer document type deklaracija) ili zalutali bajt među atributima. Svaki od njih je stao da pomera kursor, pa je jedan neočekivani bajt pretvorio parsiranje u beskonačnu petlju
• Popravljeno je čitanje CDATA sekcija u XFDF-u kao markupa: njihov sadržaj se sada uzima kao tekst elementa, a section marker se meri ispravno umesto da proguta prvi znak
• Popravljeno je prekoračenje provere veličine kod WebP chunk dužine blizu 2 GB, pa je kopija payloada čitala prekraja bafera datoteke; chunk dužine se sada proveravaju u 64-bitnoj aritmetici
• Popravljeno je oslobađanje chunk bafera kod PNG chunk dužine 0xFFFFFFFF dok je chunk još prijavljivao deklarisanu dužinu, što je kasnija čitanja uputilo na oslobođenu memoriju; predugi chunkovi se odbijaju
• Popravljeno je prekoračenje računanja veličine row bafera kod CCITT fax dekodovanja za vrlo velike deklarisane geometrije stranice, koje je moglo da piše preko bafera; row store je sada ograničen i dekodovanje se na granici lepo zaustavlja
• Popravljeno je čitanje jednog bajta prekraja scan line kod CCITT encodera za širine koje su umnožak broja osam
• Popravljeno je čitanje enhanced-metafile comment zapisa kroz 32-bitno skraćen pokazivač na 64-bitnim buildovima, što je za svaki EMF sa GDI komentarom čitalo nepovezanu adresu
• Popravljeno je objavljivanje neinicijalizovane memorije kao repa colour tabele kod 8-bitnih slika sa manje od 256 palette unosa; tabela sada deklariše svoj stvarni broj unosa
• Popravljeno je iscrpljivanje steka duboko ugnježdenim indefinite-length BER strukturama pri parsiranju kontejnera potpisa ili sertifikata; ugnježdenost preko 128 nivoa se odbija

Version 2.748.0

Fixed

• Popravljena je error correction svih 2D barcodova koje biblioteka crta: QR Code, Data Matrix, PDF417 i Aztec su generator polynomial gradili od constant termina nagore, ali su delili njime kao da vodeći termin dolazi prvi, pa je svaki simbol nosio check words koje nijedan ispravan reader ne prihvata. Check words se sada poklapaju sa worked examples iz ISO/IEC 18004, ISO/IEC 16022 i ISO/IEC 15438
• Popravljeno je gubljenje payloada kod Aztec simbola: encoder deli code word niz u mestu i caller emituje isti taj niz, pa su message words bila prepisana deljenjem i simbol nije nosio ni podatke ni ispravnu mode poruku
• Popravljeno je startovanje korena generator polynomiala Data Matrix za jedan stepen prenisko, što je dalo drugačiji polinom od onog koji propisuje ISO/IEC 16022 Annex E
• Popravljen je Data Matrix finder pattern: puna L je sada leva kolona i donji red, a naizmenični clock track gornji red i desna kolona, svaki počinje tamno u uglu koji deli sa L. Ta dva su bila zamenjena, pa readeri nisu mogli da utvrde orijentaciju simbola

Version 2.747.4

Fixed

• Popravljeno je pisanje PDF brojeva pri izmeni učitanih dokumenata sistemskim decimalnim separatorom: šivanje stranica, prekrivanje pravougaonika, žigovi teksta i slika, složeni oblici vodenih žigova i ellipse appearances sada uvek upisuju tačku, pa dokumenti izmenjeni na podešavanjima sa decimalnim zarezom (na primer nemački ili francuski Windows) više ne sadrže content streamove koje pregledači odbijaju
• Popravljeno je učitavanje Type 1 fontova koje je zavisilo od sistemske lokalizacije: FontMatrix, BlueValues, stem hints i charstring realni brojevi se čitaju kao PostScript brojevi sa tačkom, pa PFB fontovi na sistemima sa decimalnim zarezom zadržavaju metrike i konture umesto da se tiho raspadnu
• Popravljeno je čitanje veličine i boje fonta default appearance (/DA), HTML width i size atributa, FormCalc rezultata i brojeva iz job JSON po lokalizaciji procesa; sada u svim smerovima koriste invariantni format
• Popravljeno je ugrađeno crtanje barcodova koje je svoje bar pravougaonike upisivalo formatom koji zavisi od lokalizacije, što je na sistemu sa decimalnim zarezom davalo neispravan content stream
• Free Pascal buildovi sada čitaju i formatiraju operande content streama, metrike za vađenje teksta i JavaScript brojeve invariantnim formatom, u skladu sa Delphi buildovima, umesto da se vraćaju na konverziju koja zavisi od lokalizacije
• Number writer više ne prepisuje decimalni separator globalnih format podešavanja aplikacije koja ga je hostovala pri svakom pozivu, što je menjalo kako ostatak programa formatira sopstvene brojeve i bilo je nesigurno kada više niti istovremeno proizvodi dokumente

Version 2.747.3

Fixed

• Popravljeno je pisanje PDF brojeva pri izmeni učitanih dokumenata sistemskim decimalnim separatorom: šivanje stranica, prekrivanje pravougaonika, žigovi teksta i slika, složeni oblici vodenih žigova i ellipse appearances sada uvek upisuju tačku, pa dokumenti izmenjeni na podešavanjima sa decimalnim zarezom (na primer nemački ili francuski Windows) više ne sadrže content streamove koje pregledači odbijaju
• Popravljeno je učitavanje Type 1 fontova koje je zavisilo od sistemske lokalizacije: FontMatrix, BlueValues, stem hints i charstring realni brojevi se čitaju kao PostScript brojevi sa tačkom, pa PFB fontovi na sistemima sa decimalnim zarezom zadržavaju metrike i konture umesto da se tiho raspadnu
• Popravljeno je čitanje veličine i boje fonta default appearance (/DA), HTML font size atributa, FormCalc rezultata i brojeva iz job JSON po lokalizaciji procesa; sada u svim smerovima koriste invariantni format
• Free Pascal buildovi sada čitaju i formatiraju operande content streama, metrike za vađenje teksta i JavaScript brojeve invariantnim formatom, u skladu sa Delphi buildovima, umesto da se vraćaju na konverziju koja zavisi od lokalizacije

Version 2.747.2

Added

• Dodata je podrška za Free Pascal Win32: Lazarus paket se sada builduje i za i386-win32 i za x86_64-win64 kroz namenske ulazne tačke za build, smoke suite prihvataju argument arhitekture, a ispravljeni su problemi sa 32-bitnim kompajlerom i povezivanjem C simbola; kreiranje PDF, učitavanje, Flate kompresija, AES šifrovanje i rukovanje CBZ dokumentima su pokriveni na oba cilja

Version 2.747.1

Fixed

• Popravljen je ponovni pokušaj sa rotiranom maskom u ugrađenom barcode dekoderu, koji je ostavljao zaostale bajtove u netaknutim ćelijama rotirane maske, pa su se pojavljivala fantomska mastila i Code 39 simboli okrenuti za 90 stepeni nisu bili čitljivi; rotirani bafer se sada eksplicitno nuluje, pa okrenute Code 39 fotografije i skenovi dekodiraju kroz retry sa rotacijom

Version 2.747.0

Added

• Dodat je uvoz WebP slika: AddImageFromFile sada prihvata .webp fajlove kroz ugrađeni lossless (VP8L) dekoder koji implementira RFC 9649 — kanonske prefiksne kodove, prostorne meta prefiksne kodove, LZ77 povratne reference sa mapom susednih udaljenosti, keš boja i sve četiri inverzne transformacije (predictor, color, subtract-green, color indexing sa grupisanjem piksela); lossy VP8 kadrovi se odbijaju uz jasnu poruku

Version 2.746.0

Added

• Ugrađeni barcode dekoder sada čita QR simbole u bilo kojoj od osam orijentacija u kojima fotografisana ili skenirana stranica može da stigne: finder obrasci prepoznaju nedostajući ugao, a uzorkovana matrica modula se rotira ili ogleda u očekivani raspored pre dekodiranja, pa se okrenuti i ogledani snimci čitaju bez prethodne obrade

Version 2.745.0

Added

• Dodata je provera eIDAS kvalifikovanih sertifikata za učitane potpise: GetLoadedSignatureQCStatements prijavljuje ETSI EN 319 412-5 QCStatements sertifikata potpisnika — QcCompliance, QcSSCD, QcType vrednosti, QcLimitValue valutu/iznos/eksponent i PDS lokacije — plus TS 119 495 PSD2 uloge platioca i primaoca, i podiže qualified-signature heuristiku kada su QcCompliance i QcSSCD oba prisutna (odluka o poverenju prema QTSP-u ostaje pozivaocu)

Version 2.744.0

Added

• Dodato je N-up slaganje za učitane dokumente: ComposeLoadedPagesNUp raspoređuje svaku stranicu na listove složene po mreži veličine izvornog papira (2-up, 4-up, 6-up, do 16x16) za izlaz spreman za štampu, uvlači /Rotate svake stranice u matricu pozicioniranja, deli resurse stranice sa složenim oblikom i opciono iscrtava okvire ćelija od tanke linije sa podesivim međuprostorom

Version 2.743.0

Added

• FlattenLoadedAnnotations sada ugrađuje napomene koje nemaju tok izgleda umesto da ih tiho preskače: vidžeti prvo dobiju izgled polja generisan iz vrednosti polja (slučaj /NeedAppearances, uobičajen kod formulara štampanih iz brauzera), pa uneta vrednost opstaje u sadržaju stranice
• Markup napomene bez /AP dobijaju sintetizovan izgled crtan iz sopstvenih svojstava — FreeText i Stamp tekst sa /DA stilizovanjem i /Q poravnanjem, Square i Circle oblici sa /C / /IC bojom i /BS širinom, Line i Ink potezi, te Highlight / Underline / StrikeOut / Squiggly quad oznake koje poštuju /QuadPoints i /CA neprozirnost
• Skrivene napomene (zastavica /F hidden) ostaju napomene kada nemaju izgled, jer bi ugrađivanje nevidljive napomene učinilo da postane vidljiva

Version 2.742.0

Fixed

• Popravljene su Free Pascal package izgradnje koje padaju od 2.738.0: deklaracije članova za LTV dokaze i seed-value stavljene su u uslovni blok samo za Delphi dok su im implementacije bile bezuslovne, pa se Free Pascal paket više nije kompajlirao; implementacije sada nose isti uslov i paket se opet gradi

Version 2.742.0

Added

• HTML uvoz sada razrešava tabele na potpunoj mreži zauzeća, pa rowspan i colspan ćelije pravilno zauzimaju svoje kolone, a kasniji redovi preskaču zauzete slotove umesto da se pomeraju ulevo
• Visine redova tabele se računaju iz lamanja teksta ćelije fontom same ćelije umesto procene po broju znakova, pa mešani uzani i široki sadržaj više ne pravi ćelije koje se prelivaju ili su prevelike
• Širine kolona prate <col> nagoveštaje širine i atribute širine po ćeliji, a zaglavlja označena sa <thead> (ili početni redovi svi-<th>) se ponavljaju na vrhu svake nastavljene stranice kada tabela prekorači prelom stranice
• rowspan grupa ostaje cela kroz prelome stranica: redovi spojeni ćelijom koja se prostire prelaze na sledeću stranicu zajedno, pa ta ćelija nikada nije isečena

Version 2.741.0

Fixed

• Popravljeno je da Free Pascal izgradnje završavaju proces umesto da prijave grešku kada dokument zatreba neki od kodeka koje te izgradnje ne linkuju: otvaranje TIFF-a, dekodiranje JPEG 2000 ili JBIG2 slike, čitanje progresivnog ili smanjenog JPEG-a, primena ICC transformacije boja ili zahtev za Zopfli rekompresijom završavalo je proces odmah
• Svaka od tih operacija sada završi neuspehom na način koji njen pozivalac već očekuje, pa se dokument koji koristi neku od njih učita uz preskočenu tu funkciju, umesto da obori aplikaciju

Version 2.741.0

Added

• Dodata je ekstrakcija teksta po redosledu strukture: ExtractLoadedPageStructureText obilazi stablo strukture dokumenta redosledom nastanka (ISO 32000-1 14.8.4) i spaja marked-content nizove stranice po MCID-u, pa tagged dokumenti poput državnih formulara i pristupačnih publikacija izdvajaju svoj zvanični redosled čitanja umesto geometrijske pretpostavke; glifovi koje stablo nikada ne priključi padaju u geometrijski rep i broje se u izveštaju za neoznačeni deo

Version 2.740.0

Fixed

• Popravljeno je gubljenje transparentnosti obojenih glifova u Free Pascal izgradnjama: ugrađene bitmape u boji čitane su putanjom koja odbacuje alpha kanal, pa je svaki emoji ili glif fonta u boji crtan kao neproziran pravougaonik. Bitmapa sada čuva alpha po pikselu

Version 2.740.0

Fixed

• Omogućen je P-384 ECDH dogovor ključeva: završno uslovno oduzimanje u CIOS Montgomery množenju poredilo se sa P limbovima plus pozajmicom, što se prebacilo u nulu na sve-jedinicnim višim limbovima P-384 / P-521 prostih brojeva i tiho pogrešno računalo pozajmicu; poređenje sada detektuje pozajmicu bez prelivanja u sabiranju, a P-384 deljena tajna se poklapa sa OpenSSL referentnim vektorima bajt-po-bajt

Version 2.739.0

Added

• Free Pascal izgradnje sada šifruju i dešifruju dokumente: AES ulazne tačke opslužuje sopstvena FIPS-197 implementacija biblioteke umesto greške o nepodržanoj operaciji, pa se AES-128 i AES-256 zaštićeni fajlovi mogu tamo kreirati i otvarati
• AES-GCM šifrovanje i dešifrovanje, uključujući streaming kontekst korišćen za velike sadržaje, dostupno je u Free Pascal izgradnjama
• Free Pascal smoke test sada proverava šifru protiv FIPS-197 poznatog odgovora, prolazi kroz PKCS#7 i GCM round trip-ove, te kreira i ponovo učitava AES-256 zaštićen dokument uz odbijanje pogrešne lozinke

Version 2.739.0

Added

• Dodata je CSS2.1 tipografija pasusa u HTML5 uvozni engine: text-align (sa zastarelim align atributom i mapiranjem center-tag-a), letter-spacing i word-spacing kroz PDF Tc / word-space operatore, text-indent za uvlačenje prvog reda i text-decoration underline / line-through pravila, pa postojeći veb i email HTML uvozi zadržavaju centrirana zaglavlja, uvlačenja i podvlake
• Proširen je ugrađeni QR dekoder iza verzije 1: verzija simbola sada se izvodi iz finder geometrije kroz deljivost mreže (verzije 2-40 sa čistom mrežom modula se dekodiraju), ograničenje dužine u byte režimu prati ISO/IEC 18004 tabelu 7 kapaciteta po verziji, a mapa funkcionalnih modula pokriva alignment obrasce i blokove verzije za više simbole

Version 2.738.0

Added

• Free Pascal izgradnje sada kompresuju i dekompresuju dokumente izvorno: deflate kodek obezbeđuje ugrađeni backend preko Pascal zlib implementacije koja dolazi uz Free Pascal, pa FlateDecode sadržaj više ne prijavljuje grešku o nepodržanoj operaciji
• Kompresovani dokumenti se mogu kreirati i ponovo učitati pod Free Pascal-om sa podrazumevanom postavkom kompresije, a tokovi ukrštenih referenci, tokovi objekata, ugrađeni fajlovi i kompresovan sadržaj stranica svi se tamo dekodiraju
• Backend pokriva zlib i raw deflate omote, gzip omot i automatsku detekciju zaglavlja, pa SVG uvozi i fallback dekompresije sa više veličina prozora rade kao pod Delphi-jem
• Free Pascal smoke test sada verifikuje kodek kroz samotest omota i kontrolne sume plus round trip kompresovanog dokumenta

Version 2.738.0

Added

• Dodato je dopunjavanje lanca preko AIA caIssuers: HPDFFetchAIAIntermediates obilazi endpoint-e access-method 1.3.6.1.5.5.7.48.2 CMS skupa sertifikata kroz transport pozivaoca (i goli DER i PEM telo se dekodiraju), a FetchMissingIntermediates validaciona opcija usmerava preuzete intermediatere u izgradnju putanje, pa se potpisi cloud potpisnika sa samim end-entity sertifikatom validiraju umesto da izgradnja putanje propadne
• Dodato je LTV aktiviranje jednim pozivom: PopulatePAdESLTVEvidence prolazi kroz svaki učitani potpis, preuzima njegove intermediatere plus OCSP/CRL dokaze online i upisuje materijal u DSS dokumenta, čime svež B-B dokument sa potpisom nadograđuje na B-LT bez ručno sklopljenih nizova dokaza
• Dodato je sprovođenje seed-value ograničenja pri potpisivanju: CheckLoadedSignatureSeedValue čita /SV rečnik polja potpisa i proverava kandidat SubFilter, DigestMethod, Reason i DocMDP profil protiv njegovih ograničenja sa semantikom force-bit iz ISO 32000-1 12.7.5.5, pa se ograničenja autora formulara poštuju pre postavljanja potpisa

Version 2.737.0

Added

• Dodata je stroga verifikacija snimanja kroz VerifySavedOutput svojstvo: nakon upisivanja svež reader instanca sa isključenim oporavkom ukrštenih referenci ponovo učitava fajl, pa pokvarena serializacija podigne izuzetak na mestu poziva umesto da iskoči kod sledećeg potrošača
• ReproducibleOutput je proširen na šifrovane dokumente: AES-CBC tokovi koriste statičku 14*(1+i) IV konvenciju, ključni materijal i soli se izvode deterministički, a kanonski ID dokumenta normalizuje promenljive Info vremenske oznake, čime šifrovana snimanja daju bajt-identičan izlaz za regression pipeline-ove

Version 2.736.0

Added

• Dodati su resampling visokog kvaliteta i monohromski dithering kroz novu HPDFResample jedinicu: separabilni Catmull-Rom bicubic i Lanczos3 kerneli zamenjuju GDI stretch semantiku za smanjivanje slika preko ImageDownsampleKernel svojstva, a RenderOutputDither primenjuje Floyd-Steinberg difuziju greške posle kompozicije stranice, pa print-preview izlaz zadržava fotografske detalje u čisto crno-beloj tehnici

Version 2.735.2

Fixed

• Popravljeno je da Flate dekompresioni tokovi prosleđuju adresu bafer promenljive umesto samog bafera pri dopunjavanju iz izvornog toka, što je oštećivalo memoriju pri svakom čitanju i moglo je oboriti proces; pogođeni su učitavanje kompresovanih dokumenata, inflate klase tokova i helper-i za kompresiju i dekompresiju tokova

Version 2.735.1

Fixed

• Popravljeno je skupljanje na jedan red za proširive XFA polja bez izvora podataka pri poravnavanju: njihova visina se sada meri iz teksta koji sam šablon deklariše, a to je ono što takvo polje prikazuje. Polje vezano na prazan podatak i dalje se meri kao prazno

Version 2.735.0

Added

• Free Pascal izgradnje sada pokrivaju celu biblioteku: svaka jedinica se kompajlira sa FPC 3.2.2 i Lazarusom, dok je pre toga to radilo samo za osnovnu putanju kreiranja i učitavanja
• XPS, EPUB i CBZ kontejneri se mogu uvesti pod Free Pascal-om, kroz ugrađeni read-only ZIP čitač koji podržava ZIP64 veličine, stored i deflated zapise, CRC proveru i tradicionalno šifrovane zapise sa istim password callback-om kao Delphi putanja
• Poravnavanje XFA obrazaca, FormCalc engine za izračunavanje, widget runtime, komponente pregledača dokumenata, Type 1 font rukovaoci, HTML uvoz, verifikacija potpisa i job runner svi se kompajliraju u Free Pascal izgradnjama; poravnavanje XFA paketa učitanog dokumenta dodatno traži deflate kodek, koji te izgradnje ne linkuju

Fixed

• Popravljena je 64-bitna zamena bajtova u PNG helper jedinici, koja je vraćala pogrešne vrednosti na Win64 i usled čega jedinica uopšte nije bila u build-u

Version 2.735.0

Added

• Dodata je detekcija nedostajućih glifova u trenutku crtanja: TrackUnresolvedGlyphs svojstvo beleži svaki code point koji bi se preko aktivnog Unicode fonta prikazao kao .notdef tofu kvadrat, okida OnUnresolvedGlyph događaj za svaki nalaz i ne dira neregistrovane čisto-GDI dokumente
• Dodata je podrška za zastarelu kern tabelu: RegisterUnicodeTTF hvata kern tabelu iz Apple/GDI ere, a emitovanje kerninga pada na njenu format-0 binarnu pretragu parova kada font nema GPOS kern lookup-ove, čime se vraća klasični razmak parova u fontovima poput ugrađenog Arial-a
• Dodat je font fallback po segmentu unutar rasporeda pasusa: WideTextOutBox sada seče svaki prelomljeni red na code point-ovima koje trenutni font ne ume da mapira i crta svaki segment njegovim razrešenim fallback fontom, pa se mešani latinični, emoji i CJK pasusi renderuju bez tofu-a kada su fallback lanci registrovani

Version 2.734.0

Added

• Dodata je infrastruktura za RFC 3161 zahteve vremenske oznake: HPDFRFC3161BuildRequest emituje DER TimeStampReq sa svežim pozitivnim INTEGER nonce-om, opcionim policy OID-om i certReq, a HPDFRFC3161ParseResponse dekodira PKIStatusInfo zaglavlje i izvlači token, pa su TSA transport callback-ovi tri linije umesto studije DER-a
• Dodata je deklaracija ISO/TS 32002 developer ekstenzije (THotPDF.EnsureISO32002Extensions) koja pokriva EdDSA algoritme potpisa i dodatne ECDSA krive u PDF 2.0 dokumentima, idempotentna i vezana za verziju kao 32001 SHA-3 deklaracija

Version 2.733.0

Added

• Dodat je prenosiv X25519 i X448 Montgomery-ladder dogovor ključeva plus P-256 / P-521 NIST-curve ECDH sa CIOS Montgomery množenjem, čime se key-agreement (KARI) public-key primaoci mogu kreirati i odmotati u celosti u procesu; RFC 7748 i OpenSSL-generisani referentni vektori zaključavaju ponašanje ladder-a u regresioni suite
• Dodat je HPDFUnwrapKeyAgreementRecipientEnvelope zajedno sa AddPubSecAgreementKeyMaterial i AddPubKeyAgreementRecipientWithSecret ulaznim tačkama, pa se dokumenti šifrovani sa ECDH / X25519 / X448 primaocima mogu otvoriti privatnim skalrom primaoca i šifrovati bez spoljnog ECDH alata

Version 2.431.0

Added

• Novi THPDFTable engine za raspored i renderovanje (HPDFTable jedinica) slaže tabele iz deklarisanih širina kolona i redova, sa po-ćeliji tekstom, poravnanjem, bojom i preglasavanjima fonta, ColSpan / RowSpan spajanjem, automatskim prelomom reči sa izmerenim visinama redova, pozadinama zaglavlja i zebra-pruga, i automatskim nastavkom preloma stranice koji ponavlja traku zaglavlja na svakoj stranici -- sve pokreće postojeće primitive crtanja THPDFPage, tako da proizvođači više ne moraju ručno da crtaju ćelije sa Rectangle i TextOut

Version 2.430.0

Changed

• Obrada toka sadržaja i uređivanje učitanih stranica sada se skalira efikasnije na velike tekstualne i putne radne opterećenja, čuva Unicode dopunske ravni i semantiku PDF putanja, poništava keševe stranica nakon mutacija, i dovršava upise u tokove koji prihvataju delimične bafore

Version 2.428.0

Added

• THPDFPage.TextOutHTML dobija preopterećenje za prelom reči koje prima MaxWidth i lomi dugačke redove na granicama reči, plus ugrađene oznake hiperveze (<a href>) i potiskom/nadopisom (<sub>/<sup>); hiperveze se crtaju plavo i podvučeno i registruju klikabilnu URI napomenu

Version 2.427.0

Changed

• Uzastopni tekstualni nizovi koji dele isti font i veličinu više ne reemituju operator Tf pri svakom pozivu, smanjujući tokove sadržaja u dokumentima bogatim fontovima (tabele, pasusi) dok ga i dalje reemituju nakon obnove grafičkog stanja (Q) gde PDF to zahteva
• Aproksimacija elipse u THPDFPage sada koristi standardnu konstantu kubne-Bézier-kappa 0.5522847498, podudarajući se sa svakom drugom implementacijom elipse i kružnice u jedinici i uklanjajući malo odstupanje zavisno od radijusa koje je proizvodila prethodna aproksimacija 11/20

Version 2.426.0

Added

• Pregledač sada predgreje keš renderovanih stranica za stranice susedne onoj koja je upravo prikazana, koristeći pozadinsku nit pri istom DPI-u tako da sledeće okretanje stranice pogodi keš umesto ponovnog sinhronog renderovanja; novo svojstvo PrefetchRadius kontroliše koliko stranica sa svake strane se predgreje (0 ga isključuje)

Version 2.425.0

Added

• Renderer učitanih stranica sada dekodira i crta ugrađene slike (BI/ID/EI) umesto da ih preskace, proširujući skraćene parove ključ/vrednost ugrađene slike i sirove bajtove u vreme tokenizacije i smeštajući rezultat kroz isto mapiranje CTM jediničnog kvadrata korišćeno za XObject-e slika

Version 2.424.2

Changed

• Keš diska renderovanih stranica sada prikuplja sve fajlove stranica u jednom skeniranju direktorijuma i izbacuje prelivni rep u jednom prolazu, zamenjujući prethodnu petlju ponovnog skeniranja-pri-izbacivanju koja je radila u kvadratnom vremenu u odnosu na broj stranica po dokumentu
• Deduplikacija slika sada memorise SHA-256 svakog pohranjenog toka slike i upoređuje heševe pre obilaska bajtova, tako da dodavanje iste velike slike na mnogo stranica više ne ponovo čita svaki prethodno pohranjeni tok pri svakom umetanju

Version 2.424.1

Changed

• Težinski keš dekodiranih slika i podskupova fontova sada rešava preglede putem indeksa heširanja i održava redosled najnedavno korišćenih putem indeksno utemeljene dvostruko povezane liste, pretvarajući svaki Get, Put i unapređenje aktualnosti iz O(n) pomaka niza u O(1) rad, tako da renderovanje velikih višeslikovnih dokumenata više ne degradira kako se keš puni

Version 2.424.0

Changed

• CompressLoadedDocument sada poštuje CompressionLevel, obrađuje izvorne tokove u ograničenim komadima, zadržava originalni teret kada kompresija ga ne smanjuje, sigurno oslobađa zamenjene tokove i označava transformisane objekte toka prljavima tako da SaveLoadedDocument trajno pohranjuje rezultat umesto da uzme put kopiranja nepromenjenog fajla.DecompressLoadedDocument koristi istu sigurnu za vlasništvo putanju strujanja, uklanja identitetske /DecodeParms i ostavlja tokove prediktora TIFF ili PNG komprimovanim sve dok faza prediktora ne može biti sigurno dekodirana

Version 2.423.0

Added

• THPDFPage.AddCertificationSignatureField i ConfigureCertificationSignature sada stvaraju jedinstveni sertifikacioni potpis DocMDP sa sve tri nivoa dozvola i odgovarajućim povezivanjem Catalog /Perms /DocMDP, dok AttachSignatureFieldLock emituje neizravne politike SigFieldLock i odgovarajuće reference FieldMDP za opsege polja All, Include ili Exclude.THotPDF.GetLoadedSignaturePermissions izvodi ograničeni strukturni pregled istog grafa dozvola, uključujući traženu izravnost, povezivanje sa korenom, slaganje politika i dijagnostiku, bez mešanja strukture politike sa kriptografskom valjanošću ili usklađenošću sa kasnijim revizijama

Version 2.422.0

Added

• Watermark / header / footer placeholder tokens now resolve document metadata: <%Author%> / <%Title%> / <%Subject%> / <%Keywords%> / <%Producer%> are substituted alongside the existing <%PageNo%> / <%TotPage%> / <%FileName%> / date-time tokens when the new HPDFReplaceWatermarkPlaceholders overload is given a THPDFPlaceholderDocInfo record. The legacy 4-parameter signature stays for callers that only need the page / file / date-time subset

Version 2.421.0

Added

• THPDFActionBuilder.GoToEmbeddedNamedDestination and GoToEmbeddedPage create PDF 1.6 GoToE actions with standards-valid parent, EmbeddedFiles name-tree, attachment-annotation, and nested /T target paths, while preserving named or explicit destinations, optional root file specifications, NewWindow, action chaining, and PDF/A/PDF/X restrictions
• Loaded action inspection now recognises all 18 ISO 32000-1 action subtypes and returns ordered, non-executing THPDFLoadedActionInfo snapshots from catalog /OpenAction and /AA, page /AA, annotation /A and /AA, AcroForm field /AA, and outline /A sources. Dictionary and array /Next forms preserve execution order, while malformed entries, shared nodes, cycles, excessive depth, and excessive node counts stop safely with diagnostics
• Annotation action and JavaScript trigger enums now include page-open /PO, page-close /PC, page-visible /PV, and page-invisible /PI events with the required PDF 1.5 version negotiation

Version 2.420.0

Added

• Content-stream device stage 3 closes the abstraction loop: IHPDFContentDevice gains DrawXObject / DrawShading / ApplyExtGState for the Do / sh / gs operators, and the shared interpreter now dispatches them. Do is gated on cdcNeedImages so text/enum devices skip the heavy image decoding; sh and gs dispatch unconditionally. The renderer's ExecuteViaDevice path can now paint the full operator set (paths + colours + text + images + shading + ExtGState), observably equivalent to the legacy HandleOperator path. The ApplyExtGState nested procedure was promoted to a class method (DoApplyExtGState) so the device path shares it without duplication; method-resolution clauses route the three new interface entries to Dev* helpers without colliding with the pre-existing private helpers
• Document-content observer pattern: THotPDF.OnLoadedDocumentModified event fires from InvalidateRenderedPageCache (PageIndex = -1, whole document) and InvalidateRenderedPageCachePage (a specific page) so attached viewers refresh automatically. THPDFViewer subscribes in SetDocument and unbinds on detach / opRemove, calling RefreshDocument when the current page (or the whole document) is affected. Multi-view sync (several viewers on the same THotPDF) now works without each caller invoking RefreshDocument by hand

Version 2.419.0

Added

• Content-stream device abstraction stage 1: IHPDFContentDevice gains the text callback surface (BeginText / EndText / UpdateFont / UpdateCharSpace / UpdateWordSpace / UpdateHorizScale / UpdateLeading / UpdateRenderMode / UpdateRise / TextMove / TextSetMatrix / TextNewLine / ShowText / ShowTextArray) mirroring the PDF text state machine; the shared HPDFInterpretContentStreamDevice dispatcher now forwards BT/ET/Tf/Tc/Tw/Tz/TL/Tr/Ts/Td/TD/Tm/T*/Tj/TJ/'/" to the device when it declares cdcNeedText
• THPDFTextExtractDevice is a concrete device that maintains the text matrices and emits one THPDFGlyphRecord per char code (decoded via an injected IHPDFFontResolver) — observably equivalent to HPDFInterpretTokens output but produced through the device interface so the same interpreter loop drives text extraction, path enumeration and rendering
• HPDFExtractGlyphsViaDevice convenience function wraps the text-extract device + shared interpreter in one call; the existing HPDFInterpretContentStream / HPDFInterpretTokens stay untouched for current callers
• Content-stream device abstraction stage 2: THPDFPageRenderer now implements IHPDFContentDevice so the shared dispatcher can drive it through the same abstract interface. ExecuteViaDevice is the opt-in device-driven render entry; the production Execute path keeps its built-in ExecuteStream / HandleOperator dispatch, so existing behaviour is unchanged. The renderer carries every piece of state the callbacks need (graphics-state stack, font cache, GDI handles, four paint bridges) and each device method is a thin delegation, so the device-driven route is observably equivalent to the legacy route

Version 2.418.0

Added

• DecompressLoadedDocument is the inverse of CompressLoadedDocument: it walks every indirect stream carrying a /Filter /FlateDecode (name or single-element array form), inflates the payload back to raw bytes, strips the /Filter entry and fixes up /Length; streams with other filters (CCITT / DCT / JBIG2 / JPX / Crypt / RunLength) and multi-filter chains are left untouched, and corrupt Flate payloads are skipped rather than discarded
• EnumLoadedPageElements now returns the full path geometry per ekPath element, not just the bounding box: two new fields PathPoints: array of THPDFPathPoint and PathIsCurve: array of Boolean are index-parallel and carry each segment’s user-space control points with a flag distinguishing cubic bezier segments from linear ones (m / l / re edges). Callers that only read the bbox are unaffected; CAD drawing extraction, table-line detection and vector-replay consumers can now rebuild the exact curves the page drew
• New HPDFContentDevice unit introduces the content-stream device abstraction (stage 0): an IHPDFContentDevice interface with a TInterfacedObject base implementation (mirroring the proven IHPDFFontResolver pattern), a shared HPDFInterpretContentStreamDevice dispatcher that today covers the path / colour / state operator subset, and a concrete THPDFPathEnumDevice that collects one record per painted path with full point geometry. This breaks the three-way duplication between HPDFContentStream, HPDFPageRenderer.HandleOperator and HPDFCollectPathElements; stage 1 will add text/image callbacks and stage 2 will migrate the renderer onto the device

Changed

• HPDFPageRenderer header comment updated: the “TrueType/CFF glyph-outline rendering out of scope” note was stale — embedded glyph outlines have been active since v2.342.0 (DrawTextRun calls THPDFEmbeddedTTF.DrawGlyph / THPDFEmbeddedCFF.DrawGlyph with real quadratic/cubic bezier paths; GDI TextOutW is only the fallback for unmapped characters). CID fonts via Identity-H + CIDToGIDMap are covered too

Version 2.417.0

Added

• Five named loaded-document annotation helpers close the discovery gap where the existing ASubtype-parameterised helpers (AddLoadedHighlightAnnotation, AddLoadedSquareAnnotation, AddLoadedPolygonAnnotation) already produced these subtypes but callers had to know the secret: AddLoadedCircleAnnotation, AddLoadedUnderlineAnnotation, AddLoadedStrikeOutAnnotation, AddLoadedSquigglyAnnotation and AddLoadedPolylineAnnotation -- once landed, the XFDF interchange layer (which already recognises these subtype strings) picks them up for free
• AddLoadedFileAttachmentAnnotation embeds an arbitrary file payload (PDF, image, office doc) as a FileAttachment annotation with the full three-object graph the spec requires: annotation dict / Filespec dict / EmbeddedFile stream with /Subtype MIME, /Params /Size and creation/modification dates; the new THPDFFileAttachmentIcon enum (faiPushPin / faiGraph / faiPaperclip / faiTag) selects the standard pin icon viewers render
• THPDFFieldValidationOptions record + HPDFDefaultValidationOptions expose the full Adobe AF* parameter surface (Decimals / SeparatorStyle / NegativeStyle / CurrencySymbol / CurrencyBefore / RangeMin / RangeMax) that the Acrobat JS helpers accept; the existing ApplyLoadedFieldValidation(FieldIndex, Kind, DateFormat, Mask) signature is retained as a backward-compatible overload that forwards into the new record overload
• ApplyFieldValidation and ApplyFieldCalculation bring the same Format+Keystroke+Validate / Calculate template to producer-mode fields (looked up by name) so newly-created forms get the same AF* scripts as loaded ones, without writing JavaScript by hand
• CopyLoadedAnnotationsFromDocument deep-copies annotations from another loaded document directly PDF→PDF (no XFDF intermediary): reuses CopyObject to rebuild indirect references, streams and /AP appearances, rewrites /P to the destination page, optionally remaps /IRT reply chains via /NM, optionally clears /T author, and accepts a THPDFAnnotCopyFilterEvent callback for selective copy -- covers Widget/PrinterMark/TrapNet/Watermark/3D/Screen that the XFDF layer does not reach

Fixed

• ApplyLoadedFieldValidation wrote the Format JavaScript under trigger key /X (annotation-exit), which Acrobat never fires for form fields -- the script was effectively dead. Corrected to /F so the format actually runs on field commit
• ApplyLoadedFieldValidation emitted AFSpecial_FormatEx for the ArbitraryMask kind, a function that does not exist in the Adobe AF* set; only AFSpecial_KeystrokeEx(mask) is real, so the Format pass is dropped and enforcement happens at keystroke time as the spec intends
• ApplyLoadedFieldValidation unconditionally appended AFRange_Validate(true,true,0,9999999) for numeric kinds, imposing a hidden 0..9999999 range the caller never asked for; range validation now only fires when the caller explicitly sets RangeMin or RangeMax in the options record
• ApplyLoadedFieldValidation wrapped the ArbitraryMask in a JavaScript regex literal and emitted a hand-rolled validate script, but the mask is a literal format pattern ("AAA-9999"), not a regex; the validate pass is now removed and the keystroke mask carries the enforcement alone
• ApplyLoadedFieldCalculation now prepends a Format+Keystroke number-formatting pair before the AFSimple_Calculate script so the aggregated result renders as a plain number, matching common PDF viewer behaviour (without it the Calculate value displays raw)

Version 2.416.0

Added

• THPDFViewer now scrolls on hover-wheel without needing a click first: a thread-local WH_MOUSE hook (new HPDFMouseWheelHook unit, auto-installed from its initialization section) routes WM_MOUSEWHEEL to whichever THPDFViewer instance sits under the cursor, matching the behaviour of every native Windows PDF reader
• THPDFViewer is now Per-Monitor DPI v2 aware: new HPDFPerMonitorDPI unit resolves user32!SetProcessDpiAwarenessContext (Win10 1703+, DPI_AWARENESS_CONTEXT_PER_MONITOR_AWARE_V2) at runtime and falls back through shcore!SetProcessDpiAwareness (Win8.1+) and user32!SetProcessDPIAware (Vista+); the legacy HPDFEnablePerMonitorDPI is retained as an alias that forwards to the new layered helper
• THPDFViewer.RenderAtPhysicalDPI published property (default True) makes the rendering DPI baseline track the monitor’s physical DPI via HPDFGetWindowDPI, so 100% zoom on a 144 DPI panel renders at native resolution; a new WMDpiChanged handler re-renders on cross-monitor moves; set False to preserve the historical 96-DPI logical baseline
• Optional persistent disk tier for the rendered-page cache: setting THotPDF.RenderCacheFolder to a writable folder path persists every page rendered by RenderLoadedPageToBitmapCached as a PNG under <folder>\<SHA256-prefix-16>\<page>@<dpi>.png, so re-opening the same document later is instant; RenderCacheMaxDocuments (default 20) and RenderCacheMaxBytes (default 500 MB) bound the footprint with a true LRU eviction; the lookup order becomes in-memory → disk → rasterise, with disk hits back-filling the in-memory tier
• THotPDF constructor now activates the highest available per-monitor DPI tier at first instantiation in runtime mode (skipped in csDesigning), so hosts that never call HPDFEnablePerMonitorDPI explicitly still get crisp rendering on high-DPI displays

Version 2.415.0

Added

• HPDFParsePDFDate now honours the timezone suffix (+HH’mm, -HH’mm, or Z) and returns a UTC TDateTime; HPDFFormatPDFDate is the inverse formatter producing D:YYYYMMDDHHmmSS+00’00
• GetLoadedExtGStateInfo reads LW / LC / LJ / ca / CA off a named ExtGState entry on a loaded page; GetLoadedShadingCount / GetLoadedShadingName and GetLoadedPatternCount / GetLoadedPatternName enumerate the /Shading and /Pattern resource sub-dictionaries
• ReplaceLoadedPage swaps a page’s contents from a source document, SwitchLoadedPages exchanges two pages, ReverseLoadedPages flips page order in a range, ExtractLoadedPagesToPDF saves a page range as a standalone PDF, and GetLoadedPageInheritedBox resolves inherited page boxes through the page-tree parent chain
• GetLoadedFileSpecInfo reads embedded-file metadata (name / description / MIME / size), GetLoadedEmbeddedFileMIME returns the /Subtype, GetLoadedEmbeddedFileChecksum returns the /Checksum digest, and THPDFNameTreeType + GetLoadedNameTreeRootCount provide a typed enumeration of all nine name-tree categories
• HPDFEnablePerMonitorDPI dynamically enables per-monitor DPI awareness; THPDFBackgroundRenderer renders pages on a background thread with a request queue and cancellation; GetLoadedPageContentStreamCount reports whether /Contents is a single stream or an array; GetLoadedXMPValue extracts a namespace-qualified XMP property; and GetLoadedDocumentReport aggregates all diagnostic info into a JSON string

Version 2.414.0

Added

• THPDFActionBuilder.URIWithIsMap creates a URI action with /IsMap true for server-side image-map tracking, where the previous URI builder only set the bare /URI string
• AddLoadedCaretAnnotationEx adds an optional paragraph symbol (/Sy P) to caret annotations, the visual marker editors use for insert-tracking
• GetLoadedAnnotationDA parses a FreeText annotation’s /DA string into font name, font size and RGB colour components, so a caller can inspect or clone the appearance without re-parsing the raw operator string

Version 2.413.2

Fixed

• The C++Builder package now links without requiring crypt32.lib: HPDFWinCertSigner loads the CryptoAPI entry points (CertOpenStore, CertEnumCertificatesInStore, CryptAcquireCertificatePrivateKey, and the Crypt hash helpers) dynamically via LoadLibrary/GetProcAddress, matching the pattern already used by HPDFDoc.EnumerateSystemCertificates

Version 2.413.1

Fixed

• Type1 and CFF font handling now preserves parser ownership across repeated stream checks and multi-font FontSets, returns stable glyph names and bounding boxes, keeps fractional font sizes and DPI scaling, and avoids composite-glyph and private-dictionary memory errors
• The C++Builder AddDelPages, HugeFileBenchmark, and Security demos now compile for Win64, while page-operation and preflight examples release partially constructed objects safely

Version 2.413.0

Changed

• The Delphi E-Invoice demo now validates required invoice fields, amount and VAT ranges, currency syntax, and embedded XML profile compatibility before writing output
• The attach workflow now rejects identical source and output paths, reports the detected XML guideline, and combines container, PDF/A, XML profile, signature, visual consistency, Schematron, and external-report checks into one verdict

Fixed

• E-Invoice generation and manual validation no longer report a successful result when an enabled validation layer finds issues
• Loaded electronic-invoice summaries now read the invoice number, seller, and buyer from their correct XML aggregates, preventing false visible-text consistency findings

Version 2.412.0

Changed

• All Delphi demos now resolve no-argument relative assets and outputs from their executable directory while preserving the caller working directory for command-line paths
• Delphi command-line demos now provide stricter argument validation, failure exit codes, deterministic comparison inputs, and generated-document verification across page copying, text extraction, preflight, optimisation, inspection, and in-memory workflows

Fixed

• Delphi demos no longer risk page-list overflow above 100 selected pages, create an extra blank page in the add-page workflow, close unrelated PDF viewer windows, or report failed preflight checks as successful
• The E-Invoice attach workflow now rebuilds its current page correctly when a single-page source is converted, signed, and stripped of the temporary initial blank page

Version 2.411.0

Added

• E-Invoice demo: new "Attach to existing PDF" mode converts an existing PDF to PDF/A-3, embeds a Factur-X/ZUGFeRD invoice XML as a document-level attachment, and optionally signs the result with a PFX certificate

Version 2.410.0

Added

• Loaded AcroForm fields can now update flags, maximum length, text justification, per-widget rectangles, rotation, border colour, and visible or printable state, with widget enumeration for radio groups and other multi-widget fields

Fixed

• Loaded field tooltip, border-width, and background-colour edits now mark the correct field or widget dictionaries dirty, apply visual properties to every widget, and invalidate only the affected page render cache

Version 2.409.0

Added

• ActivateLoadedLinks turns bare HTTP, HTTPS, FTP, www., mailto:, and email text into positioned borderless URI annotations across a selected page range

Changed

• Loaded link creation now persists reliably in incremental updates, while automatic activation snapshots existing links once per page, skips matching URI and rectangle pairs, and invalidates each changed page cache only once

Version 2.408.0

Added

• Loaded annotations can now update their title, unique name, modification date, normalised rectangle, and standard solid, dashed, bevelled, inset, or underlined border style

Fixed

• Loaded annotation edits now mark the annotation object dirty for incremental saves, while visual edits invalidate only the affected page's cached renders and retain other warm pages

Version 2.407.0

Added

• THPDFViewerModel stores, clips, enumerates, removes, and clears persistent page-region highlights without modifying the PDF
• THPDFViewer adds a highlight interaction mode with captured marquee dragging, rotation-aware PDF coordinate recovery, configurable colour, and an OnMarqueeSelect callback

Fixed

• Viewer coordinate transforms now retain the actual render DPI below 12 and above 2400, keeping selections aligned at the 5% and 6400% zoom limits

Version 2.406.0

Added

• THPDFViewerModel creates rotation-aware page thumbnails directly at a DPI selected for caller-supplied pixel bounds, avoiding full-size intermediate page bitmaps
• Viewer-model page prefetch warms a centred neighbourhood asynchronously while limiting the scheduled pages to the rendered-page cache capacity

Version 2.405.0

Added

• THPDFPageLayout now supports PDF 1.5 plTwoPageLeft and plTwoPageRight cover-spread layouts with automatic version negotiation and strict-version fallback

Fixed

• BeginDoc now preserves the caller-selected page layout instead of always replacing it with plOneColumn

Version 2.404.0

Added

• THPDFViewerModel creates rotation-aware snapshots of bounded PDF page regions without allocating a full-page bitmap

Version 2.403.0

Added

• THPDFViewerModel converts points bidirectionally between PDF page space and rotation-aware Viewer coordinates at a caller-selected DPI

Version 2.402.0

Changed

• Viewer zoom commands now use stable standard levels from 5% through 6400%, including reversible navigation around arbitrary custom values

Version 2.401.0

Added

• THPDFViewer adds Ctrl+wheel zoom, vertical wheel scrolling, and Shift+wheel horizontal scrolling without rerendering for scroll-only input

Version 2.400.0

Added

• THPDFViewer adds keyboard page navigation, scrolling, zoom shortcuts, and Actual Size, Fit Width, or Fit Page mode selection

Version 2.399.0

Added

• THPDFViewer draws or prints the rotation-aware current view with deterministic aspect-preserving fit and centred placement

Version 2.398.0

Added

• THPDFViewerModel creates caller-owned vector EMF snapshots of any loaded page or the current view, including non-destructive 90-degree view rotation

Version 2.397.0

Added

• THPDFViewerModel saves rotation-aware page snapshots as BMP, JPEG, or PNG to files and caller-owned streams with configurable JPEG quality

Version 2.396.0

Added

• THPDFViewer.ResetView restores Actual Size, clears view rotation and search highlights while preserving the current page, with matching reset and rotation actions and batched single-render updates

Version 2.395.0

Added

• THPDFViewer and THPDFViewerModel add clockwise, counter-clockwise, and resettable view rotation that also applies to caller-owned page snapshots without changing the PDF page

Version 2.394.0

Added

• THPDFViewerModel can create caller-owned page snapshots and save the current page as BMP without constructing a Viewer control

Version 2.393.0

Added

• THPDFLoadedFormField now exposes field flags, MaxLen, page index, widget bounds, and common Required, NoExport, Multiline, and Password states
• GetLoadedFormFieldMaxLength provides direct indexed access to loaded text-field length limits

Version 2.392.0

Added

• SetDocumentAttachmentMetadata renames document-level embedded attachments and updates their descriptions before serialization

Version 2.391.0

Added

• ExtractLoadedPagesTextToStream streams selected loaded-page text as UTF-8 with custom separators and optional BOM output
• THPDFViewerModel adds form-field hit testing and deterministic keyboard navigation across page widgets
• THPDFSignatureInfo.CertificateTimeValidity reports certificate-bound and signed-time validity classifications

Fixed

• Loaded form fields without widget /P back-references can now be mapped through page annotation arrays

Version 2.390.0

Added

• THPDFWatermarkTemplate.MakeCurve and THPDFPage.AddCurveWatermark add cubic Bezier curves to loaded composites and new-document authoring

Fixed

• Loaded document metadata setters now mark the Info dictionary dirty so incremental saves persist title and author changes

Version 2.389.0

Added

• InsertLoadedBlankPage inserts a blank page with caller-defined dimensions at an exact loaded-document position
• ExtractLoadedPagesText aggregates text from a one-based page range with a caller-defined separator
• GetLoadedFormFieldNameValuePairs and SetLoadedFormFieldNameValuePairs provide batch name=value form exchange through TStrings
• CMapResourcePath supports explicit standard CMap deployment paths for services, plug-ins, and custom application layouts

Changed

• The VCL viewer now draws search-hit rectangles and refreshes when the active hit changes on the current page, while linked outline controls follow viewer document changes
• Page rendering now resolves inherited media boxes, rotation, and resources and correctly maps non-zero page origins at every right-angle rotation

Fixed

• Form-name conflicts are rejected before page insertion or append begins when merge renaming is disabled, leaving the destination page count unchanged
• Deleting loaded pages now detaches their AcroForm widget fields and removes empty field-tree branches instead of leaving references to deleted pages
• Cursor-style search helpers and viewer-model misses no longer clear managed text-match records with raw memory operations
• Automatic CMap discovery now passes the actual collection root to the text decoder

Version 2.388.0

Added

• New DeletePages removes one-based page ranges from loaded PDFs, de-duplicates overlapping selections, reports progress, and rebuilds a valid page tree for saving
• Page insertion and append merging now accept THPDFMergeOptions to copy recursive outlines, register imported AcroForm fields, and deterministically rename conflicting field names
• New AddLoadedRadioButton creates a true parent radio field with child widgets, shared export values, and complete on/off appearance states
• New SearchLoadedNext provides stateless page-local next-match search, while GetLoadedOutlineEntries returns complete recursive outline snapshots with parent and level data
• New Windows certificate-store signing overloads select a current-user or local-machine certificate by SHA-1 thumbprint and sign through either CNG or legacy CSP private keys
• New THPDFLoadedDocumentFacade exposes typed outline, form, annotation, font, and image collections with mutation and extraction helpers
• New THPDFViewer, THPDFSearchPanel, THPDFOutlineViewer, viewer model, and viewer action classes add reusable VCL page display, navigation, zoom, search, and bookmark controls
• New advanced printing, signature validation, page-thumbnail, loaded-image export, and typed loaded-document inspection demos cover the end-to-end workflows

Changed

• Loaded-document printing now builds deterministic collated or uncollated physical page sequences, supports custom paper width and length, and reports printer paper codes, names, and sizes
• System certificate enumeration now includes SHA-1 thumbprints, private-key availability, validity dates, and key-usage metadata

Fixed

• Loaded text-search result growth no longer copies managed string records with raw memory moves, preventing invalid-pointer failures on Win64
• Deleting loaded pages no longer frees shared page resources or leaves stale page-tree counts that reappear after save and reload

Version 2.387.0

Added

• New PrefetchLoadedPages renders a page range into the rendered-page cache on a background worker thread, so a viewer turning pages gets instant warm-cache hits instead of waiting for each render
• CancelLoadedPagePrefetch stops the worker and IsLoadedPagePrefetchActive reports its state; loading another document or destroying the component cancels an active prefetch automatically
• Cached rendering and the prefetch worker are serialised internally, so RenderLoadedPageToBitmapCached stays safe to call while a prefetch is running

Version 2.386.0

Added

• New FlattenLoadedAnnotations draws each annotation's normal appearance permanently into the page content at its rectangle and removes the annotation, so markup and form visuals survive in viewers that hide or cannot edit annotations
• The pass follows appearance-state dictionaries through /AS, honours the appearance bounding box and matrix when fitting the rectangle, and can be limited to one annotation subtype or a page range

Version 2.385.0

Added

• New RenderLoadedPageRegionToBitmap rasterises only a chosen user-space window of a page at the requested DPI, so very large pages can be rendered tile by tile in bounded memory at high resolutions instead of as one oversized bitmap
• Tiles align exactly: the bitmap covers precisely the requested region, so adjacent tiles reassemble into the full page without seams

Version 2.384.0

Added

• New GenerateLoadedPageThumbnails renders the selected pages of a loaded document and embeds them as JPEG page thumbnails, the previews shown in viewer page panels; the longest edge size and JPEG quality are configurable, and existing thumbnails are replaced in place
• GetLoadedPageThumbnailSize reads back an embedded thumbnail's pixel dimensions, and ClearLoadedPageThumbnails removes thumbnails from the selected pages

Version 2.383.0

Added

• EnumLoadedPageElements now reports vector path elements alongside text runs and images: each painted path yields an element with its user-space bounding box, the painting operator (stroke, fill, or both), the fill and stroke colours in force, and the segment count
• The path walker follows q/Q nesting and cm transformations, so shapes drawn inside scaled or translated blocks report their true page coordinates

Version 2.382.0

Added

• THPDFPrintOptions gains Duplex (simplex, long-edge, short-edge), PaperBin, and PrintQuality fields that are pushed into the printer device mode before the job starts; an explicit Orientation value is now applied as well
• New HPDFGetInstalledPrinters lists the system printers, and HPDFGetPrinterCapabilities reports a printer's duplex and colour support, maximum copy count, paper bins (with the codes accepted by PaperBin), and supported resolutions

Version 2.381.0

Added

• New CopyLoadedOutlinesFromDocument merges the complete bookmark tree of another loaded document into the current one, preserving titles, nesting, sibling order, and destination view parameters while remapping every destination page by a caller-supplied offset — the companion to page-append merges so combined documents keep both bookmark sets

Fixed

• GetLoadedBookmarkPageIndex now finds bookmarks beyond the first top-level entry and inside nested levels; the previous lookup only matched later bookmarks by coincidence

Version 2.380.0

Added

• New ImposeLoadedPagesNUp lays any page range onto grid sheets (any columns-by-rows arrangement, configurable sheet size and gutter) in reading order, scaling each page into its cell with optional aspect-ratio preservation
• New ImposeLoadedPagesBooklet produces saddle-stitch booklet sheets: pages are padded to a multiple of four and paired in booklet order so double-sided printing and folding yields a correctly ordered booklet
• Both imposition calls wrap the source pages as Form XObjects and append the finished sheets after the existing pages, returning the sheet count

Fixed

• Loaded-page rendering now follows an indirect reference on the resources /XObject sub-dictionary; pages whose resources arrived as separate objects skipped their images and forms silently

Version 2.379.0

Added

• SaveLoadedPagesAsImages gains two TIFF formats: ifTIFF writes one single-page TIFF file per page, and ifTIFFMulti aggregates the whole page range into one multi-page TIFF, unifying TIFF output with the existing BMP, JPEG, PNG, EMF, and WMF choices
• Both TIFF paths honour the requested rendering DPI in the image resolution tags and use lossless Deflate compression

Version 2.378.0

Added

• Loaded-page rendering now draws text rendering modes 1 (stroke) and 2 (fill then stroke) with real glyph outlines for both embedded fonts and system-font fallbacks, using the current stroke colour and line width; the clipping variants 4 to 7 paint like their base modes

Fixed

• Twelve single-operand content operators (Tc, Tw, Tz, TL, Ts, Tr, w, J, j, M, ri, i) read their operand from the wrong token position and always applied zero; character and word spacing, horizontal scaling, leading, text rise, render mode, line width, caps, joins, and miter limit now take effect when rendering loaded pages

Version 2.377.0

Added

• Loaded-page rendering now honours optional-content (layer) visibility: content inside BDC /OC marked sections and XObjects carrying an /OC entry is hidden when its layer is off, following the document's default configuration (/BaseState, /ON, /OFF)
• Optional-content membership dictionaries evaluate their /P policy (AnyOn, AllOn, AnyOff, AllOff) over the member groups
• New layer APIs on loaded documents: GetLoadedOptionalContentGroupCount, GetLoadedOptionalContentGroupName, GetLoadedOptionalContentGroupVisible, and SetLoadedOptionalContentGroupVisible to inspect and override layer states for rendering; overrides invalidate the rendered-page cache automatically

Version 2.376.1

Fixed

• Loaded-page bitmap rendering now paints image XObjects: the Do, gs, and sh resource lookups previously missed their slash-prefixed operand names and skipped the object silently
• The cm operator and Form XObject /Matrix values now concatenate in the correct order, so translate-plus-scale placement sequences (the standard image positioning idiom) land content at its intended page position

Version 2.376.0

Added

• New RegisterExponentialFunction, RegisterStitchingFunction, and RegisterPostScriptFunction APIs create standalone Type 2, Type 3, and Type 4 function objects for use wherever a function reference is accepted (shadings, halftone spot and transfer functions, tint transforms)
• RegisterPostScriptFunction validates the calculator program at registration time by trial evaluation, so malformed programs are rejected immediately instead of degrading silently in viewers
• New RegisterSeparationFunc creates a Separation colour space with a caller-supplied tint-transform function object

Fixed

• Rendering Type 2 (exponential) tint transforms with one- or three-component outputs no longer paints black; previously only four-component (CMYK) outputs decoded correctly
• Rendering Type 3 (stitching) tint transforms now supports any number of sub-functions, applies the /Encode remapping, and accepts single-entry /Bounds arrays

Version 2.375.0

Added

• Page rendering now evaluates Type 4 (PostScript calculator) tint-transform functions, so Separation and DeviceN colours and gradient shadings driven by calculator programs render their real colours instead of a grey placeholder
• The calculator evaluator covers the complete ISO 32000-1 7.10.5 operator set: arithmetic, comparison, boolean and bitwise, stack manipulation, and if/ifelse conditionals

Fixed

• Named colour-space selection (cs/CS operators) in loaded-page rendering now resolves resource names correctly; previously the lookup missed and the content fell back to the default colour space
• Loaded-page rendering now follows indirect references to array-valued colour spaces such as /Separation and /DeviceN definitions stored as standalone objects

Version 2.374.0

Fixed

• XFDF annotation import/export now preserves caret annotation default appearance data through the <defaultappearance> child and the PDF annotation DA entry

Version 2.373.0

Fixed

• XFDF annotation import/export now preserves caret annotation fringe geometry through the fringe attribute and the PDF annotation RD entry

Version 2.372.0

Fixed

• XFDF annotation import/export now preserves rubber stamp annotation rotation through the rotation attribute and the PDF annotation Rotate entry

Version 2.371.0

Fixed

• XFDF annotation import/export now preserves text annotation reply relationships through inreplyto, replyType, and the PDF annotation IRT and RT entries

Version 2.370.0

Added

• XFA numeric, date-time, and password fields with disabled horizontal scrolling now flatten to AcroForm text widgets with the PDF do-not-scroll flag

Version 2.369.0

Added

• XFA text fields with disabled scroll policies now flatten to AcroForm text widgets with the PDF do-not-scroll flag

Version 2.368.0

Added

• XFA text fields with multiLine="1" now flatten to AcroForm text widgets with the PDF multiline flag

Version 2.367.0

Added

• XFA subform access restrictions now inherit into child widgets so generated AcroForm fields stay read-only when an ancestor is readOnly, protected, or nonInteractive

Version 2.366.0

Added

• XFA choice-list flattening now maps commitOn="select" to the AcroForm commit-on-selection-change flag for generated choice fields

Version 2.365.0

Added

• XFA choice-list flattening now maps open="always" lists to single-select AcroForm list boxes instead of drop-down combo boxes

Version 2.364.0

Added

• XFA choice-list flattening now maps textEntry="1" combo lists to editable AcroForm combo boxes while preserving typed values outside the option list

Version 2.363.0

Added

• XFA choice-list flattening now prefers <items save="1"> values when a field carries separate display and saved-value option lists

Version 2.362.0

Fixed

• XFDF annotation import/export now preserves FreeText justification and tail attributes through the PDF annotation Q and IT entries
• JBIG2 document defaults now match the documented scan-friendly settings for lossy level, isolated black-pixel cleanup and black-dot size

Version 2.361.0

Fixed

• XFDF annotation import/export now preserves standard line leader and caption attributes, including leaderLength, leaderExtended, caption, leader-offset, caption-style, caption offset values and the import-side leaderExtend spelling used by compatible XFDF files

Version 2.360.0

Added

• XFA flattening now suppresses output for fields and static draws concealed by presence="hidden", presence="invisible", or presence="inactive", including descendants of concealed containers

Version 2.359.0

Added

• XFA flattening now maps field-level access="readOnly", access="protected", and access="nonInteractive" restrictions to the generated AcroForm read-only flag

Version 2.358.0

Added

• XFA flattening now preserves <choiceList open="multiSelect"> semantics by setting the PDF multi-select flag on the generated AcroForm list box

Version 2.357.0

Added

• XFA flattening now maps <ui><passwordEdit> fields to AcroForm text fields with the PDF password flag, preserving bound values while allowing readers to treat the field as password-style input

Version 2.356.0

Added

• XFA flattening now honours explicit <bind match="none"> field bindings, so fields marked as unbound remain blank instead of taking same-name values from the XFA form or datasets packets

Version 2.355.0

Added

• XFA flattening now honours simple explicit <bind match="dataRef" ref="..."> field bindings such as $record.customer.legalName, so ApplyXFAAsAcroForm and FlattenLoadedXFA preserve values stored under a different data node name before automatic same-name matching

Version 2.354.0

Fixed

• XFDF annotation import/export now preserves link annotation BorderStyleAlt children through the PDF annotation Border array, including corner radii, width and dash pattern values

Version 2.353.0

Fixed

• XFDF annotation import/export now preserves standard interior-color attributes for line, square, circle, polygon, polyline and redaction annotations through the PDF annotation IC color array

Version 2.352.0

Fixed

• XFDF annotation import/export now preserves standard annotation border style and cloudy border effect attributes, including width, dashes, style and intensity

Version 2.351.0

Fixed

• XFDF annotation import/export now preserves annotation rich text through <contents-richtext> and imports popup child geometry and open state into annotation Popup dictionaries

Version 2.350.0

Fixed

• XFDF annotation import/export now preserves additional standard annotation attributes: text open and review state values, line endpoint styles, link and redaction coords, FreeText default style, default appearance and rotation, and square or circle fringe geometry

Version 2.349.0

Fixed

• XFDF annotation import/export now follows ISO 19444-1 structures for lines, polygons, polylines and ink annotations: line exports include full start / end coordinate pairs, polygon and polyline data uses <vertices> child elements, ink data uses <inklist><gesture>, semicolon-separated coordinate pairs import correctly, and unsupported annotation subtypes no longer inflate the exported count

Version 2.348.0

Added

• LoadedPageCount property, DuplicateLoadedPage, AddLoadedBlankPage, SetLoadedPageRotationValue and GetLoadedPageBoxRect round out the loaded-document page-operation API — duplicate pages, insert blank separators, set rotation and read any of the five page boxes in one call
• GetLoadedEncryptionMethod returns the cipher name (RC4-40 / RC4-128 / AES-128 / AES-256), GetLoadedFileStructureInfo aggregates linearization / object-stream / xref-type in one call, LoadedSourceFileSize is a property, and SetLoadedPDFVersion updates the version
• StampLoadedPageImage and StampLoadedPageImageFromFile embed a JPEG Image XObject (logo / signature image / QR code) onto a loaded page at a given rectangle, InsertLoadedText draws a single-line text run, and GetLoadedPageContentLength returns the decoded byte count
• THPDFPrintOptions gains IgnoreHardMargin (offset printer hard margins so content is not clipped) and AutoRotate (landscape pages print landscape automatically)
• SaveLoadedPagesAsImages gains BMPPixelFormat / BMPMonochrome (mono / 8-bit export) and JPEGScale (1 / 2 / 4 / 8 sub-sampled JPEG decode for fast thumbnails)
• CompressLoadedDocument zlib-compresses every uncompressed stream in the loaded object graph and writes /Filter /FlateDecode, shrinking output size

Fixed

• StampLoadedPageText and StampLoadedPageImage now transparently decompress FlateDecode content streams before appending operators — previously stamping onto a compressed /Contents silently corrupted the zlib payload and the appended text/image disappeared

Version 2.347.0

Added

• AddLoadedOutline creates a new bookmark on a loaded PDF at any nesting level (ParentIndex = -1 for top-level), with a /Dest [page /XYZ x y zoom] target — the single highest-requested loaded-document feature, closing the gap that HotPDF could read/modify/delete bookmarks but never create them
• SetLoadedOutlineDestination and SetLoadedOutlineURI rewrite an existing bookmark’s target page or switch it to a URI action
• ResolveLoadedNamedDestination turns a named destination string into a zero-based page index, and AddLoadedNamedDestination registers a new anchor on the loaded document’s /Names /Dests tree
• GetLoadedBookmarkPageIndex is a convenience lookup: pass a bookmark title, get back the page it points to

Version 2.346.0

Fixed

• Image scaling quality now honours /Interpolate: HALFTONE stretch mode is used by default (smooth downscale) and COLORONCOLOR when the image explicitly sets /Interpolate false, so small raster images keep their hard edges where the author intended instead of always blurring

Version 2.345.0

Fixed

• TJ array kerning adjustments are no longer discarded: the numeric elements between string runs advance the text matrix by -value × FontSize / 1000, so tightly-spaced titles and logo lettering from Word / Illustrator place glyphs at the intended offsets
• Tw (word spacing) now also fires on the CID ideographic space (U+3000, code $3000), so justified Japanese / Chinese text gets its word spacing instead of only ASCII code 32
• Font weight / italic detection now consults /FontDescriptor /Flags (bit 18 ForceBold) and /ItalicAngle in addition to the /BaseFont name, so subset-prefixed fonts whose name carries no -Bold suffix still render at the right weight

Version 2.344.0

Added

• GetLoadedTrapped reads the /Trapped key from the Info dict (True/False/Unknown), where it was previously write-only — PDF/X preflight workflows can now round-trip the trap state
• GetLoadedDocumentMetadataXML returns the raw XMP metadata stream bytes so PDF/A documents whose Info dict is absent can still expose dc:title / dc:creator / xmp:CreateDate
• GetLoadedCollectionInfo reads the /Collection Name of a PDF Portfolio (EmbeddedFiles name tree still carries the file list)
• GetLoadedOutlineChild descends one level into the bookmark tree, returning the /First child of a top-level outline entry, so nested chapter / sub-chapter bookmarks are no longer invisible
• RotateLoadedPages rotates every page in a range by a given angle (accumulating onto existing /Rotate), the batch counterpart to per-page rotation
• SetLoadedPageBoxForRange sets a page box (Media/Crop/Bleed/Trim/Art) for every page in a range in one call
• GetLoadedViewerPreferences now also reads HideWindowUI and CenterWindow, matching the six keys the writer emits (previously only four came back)

Version 2.343.0

Fixed

• The W n / W* n clip idiom now applies the clip: the n operator builds the pending path and calls SelectClipPath instead of discarding both the path and the pending clip, so rect / container clips written as re ... W n no longer leak their contents past the boundary
• SetMiterLimit is now pushed to GDI before building the stroke pen, so sharp joins honour the PDF miter limit (default 4) instead of GDI’s default 10 — eliminating the long spikes on acute-angle joins
• Type 3 glyphs declared with d0 (colour-permitting) now explicitly clear the colour-suppress flag, so a preceding d1 glyph no longer bleeds its colour suppression into a d0 glyph

Added

• ri (rendering intent) and i (flatness) operators are now consumed and stored on the graphics state (RenderingIntent / Flatness fields), where they were previously silently skipped

Version 2.342.0

Added

• Text rendering mode operator Tr is now consumed; mode 3 (invisible) skips painting the text run entirely, so the OCR / form-background hidden text layer no longer paints as overlapping garbage glyphs — the most common Tr case in real-world PDFs. Modes 1 / 2 (stroke) currently fall back to fill pending per-glyph outline support
• Marked-content operators BMC / BDC / EMC and the DP / MP property variants now maintain a depth counter on the renderer, the prerequisite for a later round’s OCG / OCMD visibility evaluation; BX / EX compatibility operators maintain their own counter so the renderer knows it is inside a compatibility block

Version 2.341.0

Fixed

• Bezier shorthand operators v and y are now handled by the page renderer, where they were previously silently skipped — rounded rectangles, circles and the curves produced by Illustrator / PowerPoint / InDesign render correctly instead of being truncated or dropped
• DrawTextRun now honours Tz (horizontal text scaling), Tw (word spacing, applied to the space glyph) and Ts (text rise) so justified Word exports place glyphs at the right width, headings that are horizontally stretched/squeezed keep their length, and super/subscript text lifts off the baseline — previously those three text-state values were stored but never consumed

Version 2.340.0

Added

• SearchLoadedPageTextWholeWord filters the substring matches produced by SearchLoadedPageText down to those that sit on word boundaries (the glyph before the match start and after the match end must not be a word character), providing whole-word matching without padding the search string with a trailing space
• GetLoadedSearchHitRect collapses a match’s glyph range into a single bounding rectangle (user-space Left/Top/Right/Bottom, padded by a fraction of the font size), so a viewer can draw one highlight box per hit instead of walking the glyph array

Version 2.339.0

Added

• ExtractLoadedPageTextColumns reconstructs multi-column text: glyphs are clustered into baselines by a Y tolerance, each row is sorted by X, and a row splits into separate columns (tab-separated) wherever the gap between consecutive glyphs exceeds a configurable multiple of the median glyph advance — the column-aware counterpart to ExtractLoadedPageTextLayout that previously declared column detection out of scope
• THPDFPageElement now carries a BaselineRole (brNormal / brSuperscript / brSubscript) populated by EnumLoadedPageElements: a run whose font size is markedly smaller than the page median and whose Y origin sits above or below the dominant baseline is flagged

Version 2.338.0

Fixed

• Image XObjects are now placed by transforming the unit square through the current CTM, instead of being stretched across the whole page bitmap — the previous StretchDraw(Rect(0,0,W,H)) misplaced every image on the page; images now land in the rectangle the content stream actually specifies

Added

• /ImageMask stencil images are detected on the render side and painted with the current fill colour (PDF 8.9.6.1), where the renderer previously drew them as a plain greyscale bitmap

Version 2.337.0

Added

• Render-side stroke style: the page renderer now honours the J (LineCap: butt/round/square), j (LineJoin: miter/round/bevel), M (MiterLimit) and d (LineDash array + phase) operators by building a geometric pen via ExtCreatePen instead of the previous fixed CreatePen(PS_SOLID, ...), so rounded joins, dashed borders and square end caps render correctly
• Render-side gs (ExtGState) operator: the named ExtGState dictionary in /Resources/ExtGState is now consumed for LW / LC / LJ / ML / ca / CA and applied to the graphics state, where the renderer previously dropped the operator entirely
• Graphics state extended with LineCap / LineJoin / MiterLimit / LineDash / DashPhase / FillOpacity / StrokeOpacity fields, all with PDF-default initial values

Fixed

• Clip (W / W*) now sets the GDI polygon fill mode (ALTERNATE vs WINDING) before SelectClipPath, so even-odd and nonzero-winding clip intersections are no longer identical

Version 2.336.0

Security

• The render-side /Indexed colour-space parser now clamps HiVal to the spec-mandated [0..255] range, closing a buffer-overread vector where a malformed HiVal let nComps × indexHigh overflow a 32-bit byte count and read past the lookup table

Added

• AttachLoadedAnnotationMeasure writes a /Measure dictionary (PDF 1.7 §12.5.6.13) onto a Line or Polygon annotation, carrying the /NumberFormat array (unit label, decimal/fraction/round style, precision), the /Scale ratio and the /CYX isotropy factor — so a viewer can compute the real-world distance or area the shape spans

Version 2.335.0

Added

• Render-side sh (shading) operator: axial (Type 2) and radial (Type 3) shadings are now painted instead of silently dropped, so PDFs whose backgrounds rely on Word/Excel-style gradients render their colour blend. The shading is discretised into bands along its axis and each band is filled with the colour the shading’s function evaluates to at that point

Version 2.334.0

Added

• Render-side function-object evaluator HPDFEvalTintTransform now resolves Type 2 Exponential (C0 + xN·(C1-C0) with Domain/Range clamping), Type 0 Sampled (8/16/32-bit, Encode mapping, nearest-sample) and Type 3 Stitching (Bounds-selected sub-function recursion) — so Separation / DeviceN tint transforms and shading functions evaluate to real alternate-space colours instead of the v2.333.0 grey fallback. Type 4 PostScript calculators degrade gracefully
• The page renderer now wires the colour-space unit’s indirect-ref resolver and decoded-stream reader to its document access at construction time, so tint-transform stream objects can be decoded through the same path as image XObjects

Version 2.333.0

Added

• Render-side CIE-based colour spaces: CalGray, CalRGB (gamma + 3×3 matrix) and Lab (Lab→XYZ→sRGB with the 6/29 breakpoint cube) now resolve to real colours instead of degrading to black; the Bradford-adapted sRGB matrix is cached per white point so per-pixel work stays a single 3×3 multiply
• Render-side ICCBased colour space resolves through its /Alternate (or an N-based DeviceRGB/Gray/CMYK guess when Alternate is absent), so pages carrying an ICC profile display correctly without an lcms dependency
• Render-side Separation and DeviceN spot-colour spaces: the alternate space, tint-transform function reference and component count are parsed; the tint transform is wired through a pluggable evaluator so spot-colour pages are distinguishable from “colour not set” (full tint evaluation lands with the function engine)
• Generic colour operators cs / CS / sc / SC / scn / SCN now handled by the page renderer, the prerequisite for every non-Device colour space to take effect on a loaded page
• Unified colour resolution through HPDFResolveColor with the extended THPDFColorSpaceFamily and THPDFCIEParams records, replacing the per-space ad-hoc logic

Version 2.332.0

Added

• RenderSignatureFieldAppearance paints a preset signature-field appearance template — border, light fill and up to four labelled text lines (“Digitally signed by <Name>”, “Reason: ”, “Location: ”, “Date: ”) — selected via a THPDFSignatureDisplayOptions set as a convenience wrapper around AttachSignatureFieldAppearance
• EnumerateSystemCertificates walks a Windows certificate store (typical MY / ROOT / CA) via dynamically loaded Crypt32.dll and returns subject / issuer display names plus the raw DER for each certificate, the building block for a “pick a certificate / USB Key” signer UI

Security

• Signature hash algorithm is SHA-256 by default with PAdES Seed Value DigestMethods already accepting SHA-256 / SHA-384 / SHA-512, so no SHA-1 signing path exists

Version 2.331.0

Added

• RenderLoadedPageToDC draws one page straight into a caller-supplied device context (printer canvas, off-screen surface, custom TCanvas), removing the bitmap round-trip for print and high-DPI workflows
• RenderLoadedPageToClipboard places a page on the clipboard either as a 24-bit bitmap or as an enhanced metafile (vector text), so paste-into-Word / paste-into-image-editor just works
• PrintLoadedDocument with a THPDFPrintOptions record drives the VCL TPrinter through a page range, DPI, copies, collation, FitPage scaling and per-page render — the document library now ships its own print path instead of leaving every caller to wire one up

Version 2.330.0

Added

• GetLoadedPageLabel reads back the /PageLabels /Nums range that covers a given page index, returning the style code, prefix and start number — the read counterpart to SetLoadedPageLabel, so labels a caller did not create itself can now be inspected and round-tripped
• StitchLoadedPageSideBySideEx performs the side-by-side 2-up stitch with a configurable horizontal gutter and source-page scale factor, where the legacy StitchLoadedPageSideBySide was fixed to half width with no gap

Version 2.329.0

Added

• AddLoadedRubberStampAnnotation with a THPDFRubberStampIcon enum covering all 14 standard stamp names (Approved, AsIs, Confidential, Departmental, Draft, Experimental, Expired, Final, ForComment, ForPublicRelease, NotApproved, NotForPublicRelease, Sold, TopSecret) so viewers render the familiar bitmaps without a custom appearance stream
• SetLoadedAnnotationCloudyBorder turns a Square / Circle / Polygon annotation into a cloudy (cloud-burst) border by writing /BE /S /C /I plus the /IC interior colour array
• SetLoadedLineAnnotationCaps sets the /LE line-end (arrowhead) styles for Line / Polyline annotations from the new THPDFLineEndStyle enum (None / OpenArrow / ClosedArrow / Butt / ROpenArrow / RClosedArrow / Slash / Diamond)

Version 2.328.0

Added

• EnsureLoadedFieldAppearanceStream generates a /AP /N Form XObject for an existing AcroForm field from its /DA + /V + /Rect, so viewers that ignore /NeedAppearances still render the field value without a round-trip through Acrobat
• ApplyLoadedFieldValidation attaches a Format / Keystroke / Validate script trio to a field using the Acrobat AF* helpers, covering Number, Percentage, Date, Time, Currency, ZipCode, SSN, Phone and ArbitraryMask input kinds — the caller no longer has to hand-write AFNumber_Format / AFDate_FormatEx / AFRange_Validate JavaScript
• ApplyLoadedFieldCalculation attaches an AFSimple_Calculate script so a field aggregates the values of a named source field set via Sum / Average / Product / Minimum / Maximum

Version 2.327.0

Added

• Visual search-and-replace SearchAndRedactReplaceLoaded: for every hit of the needle it masks the match rectangle with a chosen colour (or skips the mask with HPDF_NO_MASK) and stamps the replacement text on top, complementing the byte-level ReplaceLoadedPageText when the original font lacks a reverse char-code table or the replacement needs a different font
• Region text extraction GetLoadedPageTextInRegion concatenates every glyph whose origin falls inside a user-space rectangle, with newlines between baselines — the building block for “copy text from this box” UI flows
• Cursor-style SearchLoadedFirst returns the first match as a single THPDFTextMatch, so callers can walk hits without managing a whole match array

Version 2.326.0

Added

• Document-wide MeasurementUnit property (muPoints / muPixels / muInches / muMM / muCentimeters / muTwips) so every high-level authoring coordinate is converted to PDF points through ToPDFUnit / FromPDFUnit
• Placeholder substitution in watermark text: <%PageNo%>, <%TotPage%>, <%FileName%>, <%ShortDate%>, <%LongDate%>, <%ShortTime%>, <%LongTime%> are resolved per page when stamping, so “Page X of Y” and dated stamps are one call
• AddTextWatermarkEx page method that combines placeholder substitution, unit-aware coordinates and a unified THPDFWatermarkBase record (angle, opacity, position presets)
• Shape-watermark page helpers AddRectangleWatermark, AddEllipseWatermark, AddLineWatermark and AddPolygonWatermark, each wrapping the path primitives in a q/Q graphics-state pair with registered fill/stroke alpha
• Unified THPDFWatermarkTemplate record with MakeText / MakeRectangle / MakeEllipse / MakeLine / MakePolygon factories plus a THPDFWatermarkTemplateArray composite type
• Loaded-document watermarking: StampLoadedPageText and StampLoadedPagesText append a transparent, rotated text run to existing pages, honouring the MeasurementUnit and the same placeholder set; StampLoadedPagesComposite applies a whole template array (text + shapes) to a page range
• Z-order control on loaded-document stamps: Underlay = True prepends the watermark stream before the existing /Contents via the array form, so the watermark renders behind the page content
• EnumLoadedPageElements returns text runs (glyphs aggregated by baseline + font) and image XObject placements as THPDFPageElement records with bounding boxes
• SaveLoadedPagesAsImages multi-format export: BMP / JPEG / PNG raster plus EMF / WMF vector, one file per page, with configurable DPI, file-name prefix and JPEG quality
• GetLoadedPageMetafile vector render of one page to a TMetafile via the new THPDFPageRenderer.ExecuteToDC path, keeping text and vector paths scalable for print, clipboard and merge workflows

Version 2.325.3

Fixed

• Aggregating batch preflight reports no longer overflows the total-bytes count when a single input file is over 2 GB

Version 2.325.2

Fixed

• Saving a document over 2 GB with object streams enabled (UseObjectStreams) no longer writes a corrupted cross-reference stream; the object offsets and cross-reference stream position, previously narrowed to a 32-bit integer, are now carried as 64-bit values through the whole write

Version 2.325.1

Fixed

• Four recovery-only scans used when a damaged PDF cannot be parsed normally — object-stream decompression, object-stream discovery, and two reference-repair passes — no longer read a file over 2 GB into a truncated buffer; each now skips that fallback on such a file instead of scanning corrupted data

Version 2.325.0

Added

• EMF/WMF import now renders EMR_GRADIENTFILL rectangle gradients (GRADIENT_FILL_RECT_H / GRADIENT_FILL_RECT_V) as PDF Type 2 axial shading patterns, mapping each TRIVERTEX colour pair to an RegisterAxialGradient call and filling the rectangle with the resulting pattern; previously this record was a documented no-op, now Word/Excel/PowerPoint gradient rectangles in EMFs render with the correct left-to-right or top-to-bottom colour blend

Version 2.324.0

Added

• EMF/WMF import now parses EMR_GDICOMMENT comments, distinguishing Adobe PDF passthrough markers (0x416F4650 = "AoFP", MS-EMF §2.3.3) from other comment types. When the Adobe marker is present the comment payload is scanned for the pdfmark keyword and surfaced via debug logging so users can identify which EMF producers emit PostScript pdfmark fragments; other comment types remain no-ops. Both HotPDF and llPDFLib previously carried only an empty stub for this record

Version 2.323.0

Added

• EMF/WMF import now explicitly recognises EMR_GRADIENTFILL as a documented no-op (PDF Type 2/3 shading patterns could express gradient fills but viewer rendering is inconsistent and GDI's per-pixel Gouraud interpolation does not map cleanly); previously this record was silently dropped without a case-table entry

Version 2.322.0

Changed

• PFX-based signing now routes inputs of 64 MB or larger through a streaming chunked signer (HPDFCMSSignPDFStreamChunked) that scans for the /ByteRange + /Contents placeholders in 256 KB rolling reads, digests the two byte-range windows via HPDFCMSSHA256StreamRanges, then copies the input stream to the output stream while patching the placeholder bytes in flight, so peak memory stays bounded by the 256 KB buffer instead of the entire file size; smaller inputs keep the fast in-memory Pos() + Move() path unchanged

Version 2.321.0

Added

• Optional-content group usage dictionaries: SetOptionalContentGroupUsage attaches a /Usage entry to a registered OCG (PDF 1.7 §8.11.4.4 Table 100) so viewers auto-show/hide layers by context. Categories View / Print / Export write <Category>State = ON/OFF; Zoom writes a real-pair Min; Language / Creator write string values
• Outline subtree copy: THPDFDocOutlineObject.CopySubtree deep-clones the entire child subtree of a node under a new parent, propagating Title / Color / Bold / Italic / Opened while minting fresh object numbers and new destinations
• Outline topology helpers IsDescendant (cycle-safe predicate used by MoveTo) and MoveTo (re-parent a node, detaching from its old sibling chain and re-attaching as the last child of the new parent, with full /Prev / /Next / /First / /Last / /Count maintenance on every affected ancestor)

Version 2.320.0

Added

• Nested optional-content /Order tree: BeginOptionalContentOrderGroup / AddLayerToOptionalContentOrder / EndOptionalContentOrderGroup build a labelled, arbitrarily nested presentation tree (PDF 1.7 §8.11.4.3 /Order) so the layers panel can show hierarchical groupings like "Background [Lines Fills Images]" instead of the historical flat list. When none of the new helpers are called the previous flat /Order mirroring /OCGs is preserved byte-for-byte

Version 2.319.1

Fixed

• Loading a PDF whose embedded JBIG2 image uses the standard Huffman coding option (rather than the more common MQ arithmetic coding) no longer fails outright: the loader now retries with the alternate decoding engine before giving up, so such images load successfully regardless of which decoding engine is preferred

Version 2.319.0

Changed

• EMF/WMF import now applies a centralised InPath gate at the ExecuteRecord entry: while a path bracket is open (BeginPath seen, EndPath/AbortPath not yet reached) only path-construction records (line/curve/polygon/move/close/end/abort plus the coordinate-system and DC-state records) reach their handlers; text and bitmap records that previously leaked into the open path are now dropped centrally, mirroring llPDFLib's entry-point guard and eliminating a class of malformed-PDF bugs from stray records inside a path bracket

Version 2.318.0

Added

• Optional-content radio-button groups: new RegisterOptionalContentRadioGroup declares mutually exclusive layer sets whose members turn each other off (PDF 1.7 §8.11.4.3 /RBGroups); typical use is single-choice layer panels like "Draft / Review / Final"

Version 2.317.0

Added

• THPDFDocOutlineObject.InsertBefore / InsertAfter splice a new sibling into the existing outline doubly-linked list at an arbitrary position, complementing the existing AddChild (append) and AddChildFirst (prepend) helpers so outline trees can be built in any order without detaching and re-attaching nodes
• EMF/WMF import now explicitly recognises the ICM/palette family (EMR_SETBRUSHORGEX, EMR_SELECTPALETTE, EMR_SETCOLORADJUSTMENT, EMR_SETICMMODE, EMR_CREATECOLORSPACE, EMR_SETCOLORSPACE, EMR_DELETECOLORSPACE, EMR_GDICOMMENT) and the no-PDF-mapping family (EMR_FRAMERGN, EMR_INVERTRGN, EMR_PAINTRGN, EMR_FLATTENPATH, EMR_WIDENPATH, EMR_SETMETARGN, EMR_OFFSETCLIPRGN, EMR_PLGBLT, EMR_POLYTEXTOUTA, EMR_POLYTEXTOUTW), forwarding to the GDI reference DC where applicable without emitting to the PDF content stream; previously these records were silently dropped, now they are documented and kept consistent with the GDI side

Version 2.316.0

Added

• New JBIG2Benchmark demo generates four PDFs from the same three-page synthetic scan, one per THPDFJBIG2Options configuration (per-image lossless, per-image LossyLevel=5, cross-page accumulated globals, rectangle symbol extraction), printing each output size so the trade-offs between the v2.310.0 scan-friendly defaults, the v2.314.0 cross-page accumulator, and the extraction modes can be compared directly

Version 2.315.0

Changed

• The cross-page accumulated JBIG2 dictionary now auto-batches: once the running glyph-width total crosses 131071 pixels the current dictionary is frozen, emitted as one /JBIG2Globals stream, and the accumulator is reset, so the next batch starts a fresh globals stream. Mirrors llPDFLib's TotalWidth-based spilling and keeps individual globals streams at a size readers handle efficiently on very large scan runs

Version 2.314.0

Added

• Cross-page accumulated JBIG2 symbol dictionary: opt in with THPDFJBIG2Options.AccumulateGlobalsAcrossPages := True (alongside the existing UseSymbolDictionary + UseGlobalSegments + native fallback switches) and consecutive 1-bit icJBIG2 images share one growing in-memory symbol dictionary and one /JBIG2Globals indirect stream, instead of each image emitting its own dictionary. New THPDFJBIG2SymbolDictionary holds the persistent glyph set with the same lossy / lossless matching the per-image encoder uses; new smoke_jbig2_accum_decode verifies two pages of different glyph layouts share a single globals object reference and decode back to the source pixels bit-for-bit

Version 2.313.0

Added

• JBIG2 global-segment streams produced by the native symbol-dictionary encoder are now content-addressed at the document level via THPDFJBIG2GlobalsPool, so images that yield byte-identical globals share one /JBIG2Globals indirect stream instead of each emitting their own; new smoke_jbig2_globals_multi smoke covers three pages of identical glyphs collapsing onto a single shared globals stream

Version 2.312.0

Added

• EMF/WMF import now covers EMR_SCALEVIEWPORTEXTEX, EMR_SCALEWINDOWEXTEX, EMR_EXCLUDECLIPRECT, EMR_CREATEDIBPATTERNBRUSHPT, EMR_SETMITERLIMIT, EMR_SETTEXTJUSTIFICATION, and EMR_SETROP2, closing the seven-record gap with llPDFLib so EMF streams emitted by older GDI toolchains no longer silently drop those records; SETMITERLIMIT and SETROP2 take effect immediately, while the others store state for a later render-side hookup without perturbing current coordinate or clip output

Version 2.311.0

Added

• HPDFCMSSHA256StreamRanges now digests the two PDF /ByteRange windows straight from a TStream in 256 KB chunks, so multi-GB signed PDFs can be hashed without first copying the whole file into an AnsiString; closes the gap with llPDFLib's stream-based CalcHash, which the existing in-memory HPDFCMSSHA256ByteRanges could not match for very large inputs

Version 2.310.0

Changed

• THPDFJBIG2Options now defaults to scan-friendly settings (LossyLevel = 5, RemoveIsolatedBlackPixels = True, BlackDotSize = 3) so 1-bit scanned images compress much smaller out of the box; set LossyLevel = 0 or Lossless = True to restore strict lossless matching

Performance

• xref table growth is now geometric (small documents +N, larger documents +25%) instead of reallocating the dynamic array on every indirect object, removing the O(n²) cost that dominated loading and building large PDFs with many objects

Version 2.309.4

Added

• Added THPDFDocOutlineObject.AddChildFirst so generated outline nodes can prepend a child item before existing siblings while preserving the saved outline order

Version 2.309.3

Added

• Added pmUseOC to THPDFPageMode so generated documents can request the optional-content layers panel with catalog /PageMode /UseOC

Version 2.309.2

Added

• Added title-string overloads for THPDFPage.AddTextAnnotation so generated text annotations can write the PDF /T title or author entry while preserving the existing icon, color, and open-state arguments

Version 2.309.1

Fixed

• Clearing THotPDF.OutputStream by assigning nil now restores normal FileName output instead of leaving the document in stream-output mode

Version 2.309.0

Fixed

• EMF/WMF import now honors EMR_EXTSELECTCLIPRGN region modes for copy, intersect, and exclude clipping while keeping EMR_SETWORLDTRANSFORM, EMR_MODIFYWORLDTRANSFORM, and EMR_SETPIXELV covered by non-GUI regression tests

Version 2.308.0

Added

• FastReport add-on design-time registration now ships as frxHotPDFDesign, placing TfrxHotPDFExport on the FastReport VCL palette while keeping the existing runtime unit and Register entry point available for compatibility

Version 2.307.0

Added

• SignPDFWithPFX now parses legacy PKCS#12 PBE-SHA1-3DES encrypted PFX files in addition to PBES2 AES-256-CBC profiles

Version 2.306.0

Changed

• Repeated calls that add the same encoded image now reuse the existing PDF image XObject while preserving distinct output for different JPEG quality settings and mask relationships

Version 2.305.0

Added

• TfrxHotPDFExport.PageRange now lets FastReport exports opt in to one-based page filtering such as 1,3-5 while reusing HotPDF's shared page-range parser

Version 2.304.0

Fixed

• XFA-to-AcroForm table flattening now lets all-growable single auto columns inherit the table content width, so fields without their own w still receive a measurable width and preserve row spacing

Version 2.303.0

Fixed

• XFA-to-AcroForm table flattening now lets growable text cells inherit fixed columnWidths values when they omit their own w, so row heights are measured and following rows stay separated

Version 2.302.0

Fixed

• XFA-to-AcroForm flattening now measures growable text fields inside nested layout="tb" and wrapped layout="lr-tb" flows, and table rows now keep growable text-cell height when positioning following fields

Version 2.301.0

Fixed

• XFA-to-AcroForm flattening now keeps text fields in layout="tb" and layout="lr-tb" flow containers when they omit an explicit h height, measuring their wrapped content height instead of skipping them as unsupported growable layout

Version 2.300.0

Fixed

• THotPDF.ExtractObjectFromStream now returns the parsed dictionary for materialized object-stream members and no longer fabricates raw-data diagnostic keys when callers inspect loaded PDF 1.5+ object streams

Version 2.299.0

Added

• THotPDF.DecompressAllObjectStreams is now public and forces loaded PDFs that used object streams to save with compact objects materialized as normal indirect objects instead of copying the source object-stream layout

Version 2.298.0

Fixed

• AcroForm field creation now rejects duplicate root field names for both new documents and loaded-document editing while preserving the valid shared-parent workflow for radio button groups

Version 2.297.0

Added

• TDBGridHotPDFExportOptions and the TDBGridHotPDFExport component now expose PDFACompliance and PDFXCompliance so DBGrid table exports can opt in to the same HotPDF standards-conformance gates used by direct document generation

Version 2.296.0

Added

• TQRHotPDFExportFilter and TdxHotPDFExportOptions now expose PDFACompliance and PDFXCompliance so QuickReport and DevExpress exports can opt in to the same HotPDF standards-conformance gates used by direct document generation

Version 2.295.0

Added

• TfrxHotPDFExport and TppHotPDFDevice now expose PDFACompliance and PDFXCompliance so report exports can opt in to the same HotPDF standards-conformance gates used by direct document generation

Version 2.294.0

Added

• Form XObject and tiling pattern canvas builders now let callers compose reusable resources through typed drawing helpers before registering them for page reuse
• THPDFExtGStateOptions now lets one ExtGState combine transparency, blend mode, line width, line cap, line join, and miter limit settings

Version 2.293.0

Added

• Native JBIG2 encoding now supports symbol-dictionary compression with optional shared global dictionaries, rectangle and image-only extraction modes, lossy pixel-difference guards, and PDF/A fallback to CCITT where JBIG2 is not permitted
• EMF/WMF rendering now handles TransparentBlt and MaskBlt bitmap records through PDF image mask and transparency paths
• FastReport and ReportBuilder native export modes now cover more object-level output, including styled memo/rich text, barcode, picture, vector shape, line, clipping, frame, dash, and URL annotation paths
• The HugeFileBenchmark demos now report working-set and peak-working-set metrics, support an opt-in memory limit, and keep generated work files separate from report output
• The Delphi PDFOptimize demo now documents producer-side compression choices for content streams, object streams, JPEG quality, CCITT, and JBIG2 output

Fixed

• Demo coverage checks now include English-baseline demo READMEs, map consolidated C++Builder samples to their actual files, and keep GUI demos disabled by default in routine test runs

Version 2.292.32

Added

• EMF/WMF hatch brushes now map to PDF tiling patterns so imported CAD drawings and reports can preserve hatch texture instead of flattening those fills to solid color

Fixed

• Loaded-document dictionary edits now mark objects dirty so SaveLoadedDocument rewrites changed PDFs instead of copying the original source after outline and object-tree edits
• Loaded outline removal now relinks sibling bookmarks, and non-rotated underline and strikeout text decorations now emit filled rectangle operators

Version 2.292.31

Added

• THPDFEmfOptions.ShowNullBrush now lets EMF/WMF rendering expose null-brush fills for diagnostic and CAD-style import workflows while preserving unfilled null brushes by default

Version 2.292.30

Added

• THPDFEmfOptions.CanvasOver now lets page Canvas replay place existing PDF content above the parsed Canvas metafile while the default keeps the current Canvas-on-top order

Version 2.292.29

Added

• THPDFEmfOptions.Redraw now lets EMF/WMF callers keep the default temporary redraw path or opt out and parse the original metafile directly

Version 2.292.28

Added

• THPDFEmfOptions.UseFrame now lets EMF/WMF rendering clip imported output to the EMF header frame for metafiles that rely on declared frame bounds

Version 2.292.27

Added

• THPDFEmfOptions.ShowNullPen now lets EMF/WMF rendering expose null-pen outlines for diagnostic and CAD-style import workflows while preserving invisible null pens by default

Version 2.292.26

Added

• THotPDF.SetFormFieldTooltip now lets applications assign AcroForm /TU field hints by field name for widgets created through the existing Add... field methods

Version 2.292.25

Fixed

• TfrxHotPDFExport native-object mode now preserves TfrxPictureView clipping and frame rendering when picture views are written directly as HotPDF image XObjects

Version 2.292.24

Added

• TfrxHotPDFExport native-object mode now maps supported horizontal one-dimensional FastReport barcode views directly to HotPDF barcode operators, while keeping human-readable text, checksum generation, supplemental text, rotation, colored bars, and unsupported symbologies on the existing fallback path

Version 2.292.23

Added

• TppHotPDFDevice native draw-command mode now maps supported one-dimensional ReportBuilder barcode draw commands directly to HotPDF barcode operators, while preserving the enhanced-metafile fallback for commands that need human-readable text, add-on codes, check-digit calculation, colored bars, rotation, or unsupported postal symbologies

Version 2.292.22

Fixed

• Automatic PDF viewer launch can now be suppressed in non-interactive runs with HOTPDF_SUPPRESS_AUTO_LAUNCH=1, and the bundled test and smoke runners enable that guard by default so non-GUI regression runs do not open viewer windows

Version 2.292.21

Added

• THPDFPage.ShowMetafileEx now has a per-call THPDFEmfOptions overload, letting callers override EMF/WMF rendering settings for one metafile draw while preserving document-level defaults
