PDFium VCL Component Funktioner

Core Komponents

• TPdf - Main PDF dokument handling komponent for opening, navigating, extracting tekst, and editing PDF dokuments
• TPdfView - Visual komponent for displaying and interacting with PDF sides
• TPdfReadingSession - Read-aloud orchestration komponent for host TTS engines and TPdfView word tracking
• TPdfThumbnailView - Scrollable thumbnail side panel for side navigation

Dokumentoperationer

• Dokumentindlæsning - Indlæs PDF-filer fra disk, hukommelsesstrømme, byte-arrays eller on-demand TStream-adaptere via LoadCustomDocument. PDFium læser blokke efter behov, så multi-GB-dokumenter og eksterne / databaseunderstøttede kilder ikke kræver en indledende kopi i hukommelsen
• Adgangskodebeskyttelse - Open password-protected PDF dokuments and report effective UserPermissions for the authenticated session
• Dokumentoprettelse - Build new PDF dokuments from scratch with CreateDocument, AddPage, AddText, AddImage, AddPicture, AddJpegImage, and CreatePath
• Dokumentgemning - Save modified dokuments with various options (incremental, remove security) and explicit PDF target versions from PDF 1.0 through PDF 1.7
• PDF/A-1b Output - SaveAsPdfA / SaveAsPdfAToStream efterbehandl basissave med en inkrementel opdatering, der indsætter en XMP-metadata-strøm, et sRGB ICC OutputIntent og et opdateret dokumentkatalog, så resultatet er PDF/A-1b-kompatibelt. Brugerdefinerede ICC-profiler understøttes via TPdfASaveOptions.IccProfileData
• PDF/A Validation - ValidatePdfA og den skrivebeskyttede PdfAConformance-egenskab scanner et åbent dokument for XMP pdfaid-markører, OutputIntent med indlejret ICC, tilstedeværelse af kryptering og rapporterer overensstemmelsesniveauet (pac1a, pac1b, pac2b, pac3b, pacNone eller pacUnknown) plus en liste over TPdfAValidationIssue-poster, der beskriver hvert fundet problem
• PDF Version Compliance Validator - When SaveAs targets PDF 1.0 through PDF 1.7 the writer rejects any dictionary entry, filter, annotation subtype, action type, font, color space, or encryption parameter introduced after the chosen target version (e.g. JBIG2Decode, MarkInfo, OutputIntents, AES / AES-256, Polygon / Caret / Watermark / Redact annotationer, JavaScript / Trans / SetState actions)
• Stream Komprimering - Automatic FlateDecode compression ensures all PDF streams are optimally compressed when saving; set Compressed := False to opt out for debug pipelines
• Dokumentsammenfletning - Import sides from other PDF dokuments
• Import af sidesubset - ImportPagesByIndex kopierer et eksplicit nulbaseret indeksarray fra et kildedokument, med InsertAt = 0 for at indsætte før side 1 eller InsertAt = PageCount for at føje til sidst. Send et tomt indeksarray for at importere hver kildeside
• N-up-komposition - ImportNPagesToOne returnerer en helt ny TPdf, hvis sider er NumX×NumY-kompositter af kildedokumentets sider, størrelsessat i PDF user units (1 unit = 1/72 in)
• Sideomrokering - MovePages reorders sides in place using a zero-based index array and a destination index for the first moved side
• Form XObject Page Reuse - CreateXObjectFromPage manufactures a reusable TPdfXObject handle from any side of another dokument; InsertFormObjectFromXObject indsætter ÉN kopi af den indpakkede side i den aktuelle side. Ideel til vandmærker, skabelonoverlays og "stempel én side på mange"-arbejdsgange. Det destination sideobjekt kan positioneres, skaleres og roteres via FPDFPageObj_SetMatrix and the TPdfMatrix helpers
• Sidehåndtering - Add, delete, and manipulate individual sides; AddPage(0, ...) inserts the very first side and activates it immediately
• Sidebokse - Læs og skriv MediaBox, CropBox, BleedBox, TrimBox og ArtBox på den aktuelle side
• Katalogsprog - Read and write the dokument language stored in the catalog /Lang entry
• Trailer File IDs - Læs permanente og skiftende trailer /ID-poster som binære bytes
• Dokumentets JavaScript-handlinger - Enumerate dokument-level JavaScript name-tree action names and scripts
• Tagged PDF Structure Tree - Inspect logical structure elements, accessibility tekst, language, marked-content IDs, and hierarchy for tagged PDF sides
• Fremviserpræferencer - Read PrintCopies, PrintPageRanges, PrintScaling, and PrintPaperHandling from the dokument's viewer-preference dictionary; saved PDFs default to a Fit Height first-side open action

Tekstoperationer

• Tekstudtræk - Extract tekst from PDF sides with character-level precision via Text, TextInRectangle, indexed Character, CharacterRectangle, and CharacterOrigin properties
• Sentence-Level Reading Enheds - TPdf.ReadingEnheds, TPdf.DocumentReadingEnheds, TPdfView.ReadingEnheds and BuildReadingEnheds expose sentence-sized TPdfReadingEnhed records for synchronized TTS listen-reading
• Word-Level Reading Highlighting - TPdf.PageWordBoxes, TPdfView.PageWordBoxes, BuildWordBoxes, WordBoxIndexAtCharIndex, TPdfView.SelectWordBox, TPdfView.SelectWordSpan, TPdfView.TrackReadingWordAt, TPdfView.SetReadingWord, TPdfView.ClearReadingWord, ReadingWordColor, ReadingWordFollow Mapper en sidekarakterforskydning til den tilhørende TPdfWordBox, fremhæver den og returnerer ordindekset; fremhæver én TPdfWordBox som det aktuelle talte ord på TPdfView; rydder den aktuelle ordniveau-læsemarkør-overlejring på TPdfView; styrer overlejringens farve, der bruges til den aktuelle ordniveau-læsemarkør; styrer, om TPdfView ruller det aktuelle talte ord ind i visningen, mens læsningen følges
• Read-Aloud Session Orchestration - TPdfReadingSession, TPdfSpokenText, SpokenTextAppend, BuildSpokenTextFromWords, SpokenToPageChar og EstimateSpokenWordIndex koordinerer værts-TTS-motorer, talte chunks, tilbagekald af ordpositioner, estimeret tempo, håndtering af pause/genoptag og opdateringer af TPdfView's ordmarkør
• Text Search - Find tekst with case-sensitive, whole word, and consecutive søgning options using FindFirst, FindNext, FindPrevious
• Søgehøjmarkeringslag - TPdfView.HighlightSearchText scans the current view side and paints a real alpha-blended HighlightColor overlay over every match on each redraw, returning the match count ClearHighlight removes the overlay; navigating to a different side clears it automatically because matches are side-specific HighlightColor defaults to clYellow and is published so applications can theme it
• Character Egenskaber - Access font size, weight, angle, and positioning for individual characters with the CharacterAngle, CharacterFontSize, CharacterFontWeight, CharacterGenerated, CharacterIsHyphen, and CharacterMapError indexed properties
• Understøttelse af europæiske tegn - AddText automatically loads and caches the matching system TrueType font before creating a tekst object, so accented Czech, French, German, Spanish, Portuguese, Polish, and Turkish characters that PDFium's built-in standard fonts cannot represent now render correctly without any code change
• Teksttilføjelse - Add new tekst to PDF sides with custom fonts, colors, transparency, and rotation
• Positionering af tekstobjekt - Set per-character positions for existing tekst objects through SetTextPositions and TPdfSingleArray
• Skriftinformation - Retrieve font properties including family name, embedding status, italic angle, ascent / descent, and raw font data on a per-side-object basis

Annoteringsunderstøttelse

• Annotation Typer - Support for tekst, link, highlight, underline, strikeout, and many other annotation types
• Annotation Creation - Create new annotationer programmatically
• Annotation Editing - Rediger eksisterende annotationsegenskaber, herunder farve, gennemsigtighed og indhold
• Link Annotations - Håndter interne og eksterne links med handlingssupport

Formularunderstøttelse

• Voice Form-Filling Accessors - FocusedFormFieldValue, FocusedFormFieldName og FocusedFormFieldDetails på TPdf og TPdfView eksponerer den aktuelle logiske formularfeltværdi, navn og TPdfFormFieldInfo til tastatur- eller stemmestyret formularudfyldning
• Form Typer - Support for AcroForm and XFA formularer
• Form Fill - Interaktiv formularudfyldning med JavaScript-understøttelse
• V8 DLL Selection - Indstil EnableV8Engine før indlæsning for at bruge pdfium.v8.dll fra den tilsvarende DLLs\Win32- eller DLLs\Win64-mappe og anmod om tilgængelighed for V8/XFA-hjælperen via V8FeaturesAvailable, XfaBStrHelpersAvailable og GetRecommendedV8Flags
• Field Access - Læs og skriv formularfeltværdier efter indeks eller position
• Field Information - Få adgang til felttype, flag, navn og andre egenskaber
• Field Flags - Opdater AcroForm-feltflag efter indeks eller placering gennem SetFormFieldFlags / SetFormFieldFlagsAt, inklusive skrivebeskyttede, påkrævede, adgangskode- og multi-valg-flag
• Form Flattening - GenerateFormAppearances regenererer /AP appearance stream for hver formularwidget på hver side, og FlattenPage / FlattenAllPages bake annotationer and form fields into static side content (non-editable)
• Form Widget Tekstmarkering & Undo / Redo - On the focused AcroForm widget the view exposes GetSelectedFormText (currently selected tekst), SelectAllFormText (select every character), and FormUndo / FormRedo / FormCanUndo / FormCanRedo (styr PDFiums redigeringshistorik pr. widget). Alle seks kortslutter sikkert, når visningen er inaktiv, eller ingen widget er fokuseret

Billedoperationer

• Image Extraction - Extract bitmaps from PDF sides with the indexed Bitmap property; iterate BitmapCount to save every billede to disk
• JPEG Insertion - AddJpegImage tager en TStream med rå JPEG-bytes og indlejrer billedet som et /DCTDecode XObject uden omkodning
• Picture Support - AddPicture accepterer et TPicture-objekt med automatisk formatkonvertering gennem de registrerede VCL-/LCL-grafikklasser
• Direct Image Insertion - AddImage(FileName) genkender ethvert format, der er registreret med VCL- eller LCL-grafikenhederne (BMP, PNG via PngImage, JPG, ...) og deler AddPicture-pipelinen AddImage(TBitmap) skips the TPicture intermediary, which simplifies callers that already hold a TBitmap from rendering or batch generation work
• Image ICC Profile - Image side objects expose their embedded ICC profile data when present (binding for FPDFImageObj_GetIccProfileDataDecoded)
• Thumbnail Generation - Generate current-side thumbnail bitmaps via the Thumbnail property or render any one-based side through TPdf.RenderPageThumbnail without changing PageNumber

Helper Enheds

• Async Infrastructure - FPdfAsync eksponerer IPdfCancellationToken / IPdfCancellationTokenSource for samarbejdende annuller-fra-brugergrænsefladen-semantik, en genanvendelig PdfNoCancellationToken-singleton og en letvægts TPdfFuture<T>-hjælper, der kører en worker på en baggrundstråd og sender en TPdfFutureResult<T>-konvolut tilbage til hovedtråden, der skelner mellem tilfælde af succes, annullering og fiasko
• Stream Adapter - TPdfStreamAdapter bygger bro over en Pascal TStream til PDFiums FPDF_FILEACCESS-callbacks, så LoadCustomDocument læser blokke on-demand i stedet for at buffere hele PDF'en i hukommelsen
• Matrix Composition - FPdfMatrix wraps PDFium's FS_MATRIX with an OO API for Translate, Scale, Rotate, HorizontalFlip, VerticalFlip, CentralFlip, Skew, and Multiply Multiply snapshots the six matrix elements before computing the new row values, avoiding the alternative-Pascal-implementation pitfall where earlier elements get overwritten during the same call and produce incorrect compositions
• Cancellable Progressive Rendering - TPdf.RenderPageProgressive drives PDFium's FPDF_RenderPageBitmap_Start + RenderPage_Continue loop and polls an IPdfCancellationToken between iterations via the IFSDK_PAUSE callback so long high-DPI renders can abort mid-page instead of blocking until completion. Returns a TPdfProgressiveStatus of prsDone, prsCancelled, or prsFailed
• Zero-Copy Render Path - RenderPage / RenderTile / RenderPageProgressive write PDFium output directly into the destination TBitmap's DIB buffer instead of staging through an internal buffer, saving one width × height × 4 bytes memory copy per render - most noticeable at high DPI (thumbnail panels, print-quality export, batch export). A per-scanline fallback path is preserved when the destination DIB cannot be wrapped safely
• Low-Vision Bitmap Transformularer - InvertPdfBitmap, GrayscalePdfBitmap and DuotonePdfBitmap transform rendered 32-bit TBitmap pixels in place for inverted, grayscale, or two-colour low-vision views
• Live Svagsynet visninging - TPdfView.Options supports reInvert and reNightDuotone, with NightDuotoneInk and NightDuotonePaper controlling the live night palette before overlays are painted

Tegneoperationer

• Path Drawing - Opret stier med linjer, Bezier-kurver og lukkede former
• Object Removal - Remove side objects and regenerate side content from TPdf or TPdfView
• Fill and Stroke - Konfigurer udfyldningstilstand (fill), farver, gennemsigtighed og stregegenskaber (stroke)
• Blend Modes - Understøttelse af forskellige PDF-blendtilstande
• Line Styles - Konfigurer linjeafslutning (line cap), linjesamling (line join) og stregtykkelse (stroke width)

Digitale signaturer

• Signature Detection - Detect and enumerate digital signatures in PDF dokuments
• Signature Information - Få adgang til signaturindhold, byteområde, underfilter, årsag og tidspunkt
• MDP Permissions - Query dokument modification detection and prevention permissions

Understøttelse af vedhæftede filer

• Attachment Access - Read, create, modify, and delete embedded file vedhæftnings
• Attachment Names - Access vedhæftning filenames
• Attachment Typer - Read embedded file MIME subtype values when present

Navigation

• Bookmarks - Navigate dokument bookmarks with hierarchical support via the Bookmarks array, BookmarkChildren, HasBookmarkChildren, and BookmarkFrom traversal helpers
• Named Destinations - Få adgang til navngivne destinationer efter indeks eller navn gennem Destination, DestinationByName og DestinationCount
• Page Labels - Retrieve side labels for each side via PageLabel; useful when dokuments use Roman numerals for front matter
• Web Links - Detect and navigate web links on sides with WebLink, WebLinkCount, and TPdfView.WebLinkAtPos
• Link Annotations - Access link annotationer with action and destination information through LinkAnnotation, LinkAnnotationCount, and TPdfView.LinkAnnotationAtPos
• Sikker håndtering af linkklik - TPdfView raises OnAnnotationLinkClick / OnWebLinkClick events before automatic goto / URI handling, with launch actions disabled by default. Link click detection runs only when the gesture is a click rather than a drag, using a fresh MouseDown anchor so panning gestures still flow through the existing scroll path unchanged

Gengivelse

• Rendering i høj kvalitet - Render sides to device contekst, bitmap, or tile through RenderPage / RenderTile, with zero-copy direct writes into the destination DIB buffer
• Cancellable Progressive Rendering - RenderPageProgressive drives PDFium's progressive loop and polls an IPdfCancellationToken between iterations, returning prsDone, prsCancelled, or prsFailed. The bitmap holds the partial work done so far when cancelled
• Render Options - LCD tekst optimization (reLcd), annotationer (reAnnotations), grayscale, and udskrivning mode flags
• Skia Hooks - Low-level bindinger for FPDF_RenderPageSkia og FPDF_FFLDrawSkia er tilgængelige, når kalder-koden leverer et eksternt SkCanvas (afhænger af medfølgende DLL-eksporter)
• Print Mode Selection - Set EMF, tekst-only, PostScript, pass-through, billede-mask, and Type 42 PDFium print modes via SetPdfPrintMode with TPdfPrintMode
• Asynkront lag - TPdfView kan vise et valgfrit indlæsnings-overlay, mens programejede arbejdere gengiver med separate TPdf-instansers
• Page Rotation - Understøttelse for 0-, 90-, 180- og 270-graders rotation (ro0, ro90, ro180, ro270)
• Transparency Detection - Transparent property reports whether any object on the current side has transparency, including blend modes and partial alpha

Visning (TPdfView)

• Viser Modes - dmSingleContinuous, dmTwoPageContinuous, and dmTwoPageContinuousWithCover (the cover side stands alone, then continues with two-side spreads). The unit-level ComputeSpreadPages helper exposes the spread-side math without instantiating a viewer
• Fit-tilstand - FitMode chooses how the side sits in the viewport: pfmNone (manual zoom), pfmActualSize (100%), pfmFitPage (whole side fits in the viewport), and pfmFitWidth (side width matches viewport width). The active fit mode is re-applied automatically on Resize and when the current side changes; setting Zoom directly cancels the active fit mode (FitMode reverts to pfmNone), matching the standard PDF viewer convention
• Zoomkontrol - Variable zoom with PageZoom, PageWidthZoom, PageHeightZoom, and ActualSizeZoom per-side helpers
• Sidefarve - PageColor kobler den gengivne PDF-sides baggrund fra det omgivende kontrolelements Color. Default is clWhite, so PDF sides now render as paper-white regardless of the host application's theme. Dark-mode viewers can keep the scroll area dark while leaving the actual PDF side white (or any color the application picks)
• Interactive Tekstmarkering - End-user drag-to-select tekst on PDF sides, with hit-test auto-switching between selection and pan: clicking on a character starts a selection drag, clicking on whitespace pans. Double-click selects the word, triple-click selects the line, Ctrl+A selects the side (both sides in spread mode), Ctrl+C copies as CF_UNICODETEXT, Shift+arrows extend selection, hover over tekst switches the cursor to crIBeam, and dragging into a viewer edge auto-scrolls the side. New published SelectionColor and OnSelectionChange; new public HasSelection, SelectedText, SelectionCharCount, ClearSelection, SelectAll, CopySelectionToClipboard. Spread display modes select across both visible sides with CR/LF joining. A default right-click Copy popup is auto-attached when the host has not assigned its own PopupMenu. Gated by the v1.17.0 AllowUserTextSelection flag for kiosk hosts
• Koordinatmapping - Convert between viewer device coordinates and PDF side coordinates with DeviceToPage / PageToDevice, including overloads that take a TRect and return a TPdfRectangle
• Tekstmarkering og hit testing - Resolve characters under viewer points with CharacterIndexAtPos and paint tekst selection highlights via PaintSelection
• Mus og tastatur - Full input device support with mouse drag scrolling, PgUp / PgDn / Ctrl+Hjem / Ctrl+End shortcuts, and wheel-up / wheel-down side navigation. Ctrl+wheel is reserved for application zoom and skipped by the navigation handler
• Låsning af brugerinput - AllowUserPageChange controls keyboard side shortcuts, ChangePageOnMouseScrolling controls wheel side jumps, and AllowUserTextSelection controls mouse / keyboard tekst-selection input. All three default to True; flip them False to lock down kiosks, preview panes, or read-only embeddings without subclassing
• Asynkront renderingslag - AsyncRendering, LoadingText, and LoadingColor draw a small "Loading..." indicator over the rendered side so applications using their own worker for long renders share a consistent visual affordance. Defaults preserve existing behavior TPdf now serializes render and side-unload calls per instance; applications still own worker dispatch and must avoid mutating a dokument while a render is in flight
• Sikker håndtering af linkklik - LinkOptions is a published set that controls automatic behavior for the four PDF link action types: loAutoGoto (side jump), loAutoOpenURI (ShellExecute), loAutoLaunch (ShellExecute), and loAutoEmbeddedGoto (reserved). Defaults enable loAutoGoto and loAutoOpenURI only; loAutoLaunch and loAutoEmbeddedGoto stay off so a stray click cannot run an arbitrary program OnAnnotationLinkClick and OnWebLinkClick udløses før enhver automatisk handling og lader programmet markere hændelsen som Handled eller omdirigere den
• Formularinteraktion - Interactive form editing within the viewer, plus the v1.23.0 selection / Undo / Redo helpers
• Visuel styling - PageShadowSize, PageShadowColor, and PageBorderColor paint an optional drop shadow under the side rectangle and a one-pixel border around it; SmoothScroll now animates line/side scrollbar commands in timer-driven segments while thumb tracking remains immediate
• Miniaturenavigation - TPdfThumbnailView (unit FPdfThumbnail) renders one side thumbnail per row in a scrollable side panel with hover and selection highlighting plus click-to-go navigation. Designed to sit next to a TPdfView. Egenskaber: Pdf, CurrentPageIndex, ThumbnailWidth, ThumbnailHeight, TextColor, HoverColor, SelectionColor, BorderColor; event: OnPageClick

Komprimering

• Automatic Komprimering - When the Compressed når egenskaben er True (standard), sikres det, at alle PDF-strømme er FlateDecode-komprimerede ved gemning
• Efterbehandling - The compression engine scans saved PDF data and compresses any uncompressed streams using zlib maximum compression
• Genopbygning af krydsreference - Automatically rebuilds the xref table when stream compression changes byte offsets
• Nul overhead - If all streams are already compressed, the data passes through without modification

Sikkerhed

• Understøttelse af adgangskode - Open password-protected PDF dokuments
• Permissions - Read dokument and user permissions; the SecurityAudit demo combines permissions, attachments, document JavaScript, URI / Launch links, signatures, XFA, and V8 availability into a read-only risk surface with TXT / JSON report save and TXT copy actions
• Sikkerhed Removal - Save dokuments with security removed (when authorized)

Udskrivning

• Udskrivningstilstande - Choose between EMF, tekst-only, PostScript Level 2 / 3, PostScript pass-through, EMF billede-mask, and Type 42 print modes through the global SetPdfPrintMode function
• Fremviserpræferencer - Surface dokument author intent through PrintCopies, PrintPageRanges (one-based side ranges), PrintScaling, and PrintPaperHandling; SetPdfPrintPaperHandlingDevMode maps the duplex hint into Windows DEVMODE.dmDuplex
• N-up Udskrivning - The Delphi, C++Builder, and Lazarus PrintPreferences demos show N-up sheet composition (1 / 2 / 4 / 9 pages per sheet) with odd / even page filtering, grayscale rendering, optional 1-pixel cell borders, PDF author print preferences, and duplex intent mapping via SetPdfPrintPaperHandlingDevMode
