HotPDF Component do tworzenia i edycji PDF w Delphi

Natywne tworzenie i edycja PDF dla Delphi i C++Builder

HotPDF to komponent PDF Delphi i C++Builder z kodem źródłowym dla aplikacji, które muszą bezpośrednio z kodu VCL tworzyć, edytować, zabezpieczać, podpisywać, weryfikować i składać dokumenty PDF. Podstawowy przepływ autorski nie wymaga zewnętrznego runtime PDF i jest przeznaczony dla oprogramowania Windows tworzonego w RAD Studio.

Use HotPDF when your application needs programmatic page drawing, Unicode text output, font embedding and subsetting, forms, annotations, image import, PDF merge/edit operations, encryption, digital signatures, standards-aware output, and lightweight preflight automation from one native API surface.

HotPDF supports RAD Studio XE5 through RAD Studio 13.1 Florence for Delphi and C++Builder, including Win32, Win64, and Win64x workflows.

Główne możliwości

• Create new PDFs, add pages, draw text and vector graphics, register reusable Form XObjects, place images, and save to files or caller-owned streams.
• Load existing PDFs, inspect page boxes, search bookmark destinations, copy pages, insert pages, extract pages, reorder pages, delete pages, merge documents, stamp or watermark content, and update document information.
• Add hyperlinks, named destinations, outlines, file attachments, comments, popups, highlight annotations, free-text annotations, redaction annotations, watermark annotations, page thumbnails, layers, page transitions, and viewer preferences.
• Create AcroForm fields, generated appearance streams, signature fields, multi-line and comb text fields, rich-text field values, XFA packet containers, form-field trigger wrappers, and multiple Unicode fonts in the AcroForm resource dictionary where the selected standard profile allows them.
• Inspect, update, rename, remove, or flatten fields in loaded AcroForm documents before saving an edited copy.
• Embed and subset TrueType, Type 1 PFB, OpenType-CFF, and CID-keyed CFF fonts for compact multilingual output, including CJK-heavy documents.
• Generate Unicode text, right-to-left text, vertical text, supplementary-plane characters such as emoji, Arabic / Persian / Urdu shaping, Latin standard ligatures, Devanagari reordering, and OpenType GSUB-based glyph output with matching /CIDToGIDMap, /W, and /ToUnicode integration.
• Import JPEG, bitmap, TIFF, JPEG2000, JBIG2, WMF, and EMF content, with zlib-ng Flate compression and libjpeg-turbo backed JPEG handling.
• Protect documents with passwords, AES-128, AES-256, PDF 2.0 AES-256 R6, public-key recipient encryption, and permission flags.
• Sign PDFs with in-process PFX / PKCS#12 support and PAdES B-B, B-T, B-LT, and B-LTA workflows including RFC 3161 timestamps and DSS / VRI dictionaries.
• Twórz raporty preflight w formacie tekstowym, JSON i HTML, stosuj profile i presety preflight, agreguj wyniki batch, osadzaj dowody raportu w PDF, porównuj raporty i wykonuj ukierunkowaną walidację PDF/VT.
• Use optional PDF backends for FastReport, QuickReport, ReportBuilder, and DevExpress ExpressPrinting when existing report layouts should emit through HotPDF.

Standaarden, ondertekening en validatieworkflows

HotPDF supports standards-aware PDF generation workflows for PDF/A-1, PDF/A-2, PDF/A-3, PDF/X-1a, PDF/X-3, PDF/X-4, and PDF/UA-1. It also includes preflight and focused PDF/VT validation helpers for review and automation workflows. The component exposes profile-specific switches and guards so calls that would break the selected profile can fail early instead of silently writing a non-conformant PDF.

Przepływ pracy	HotPDF support	Odpowiedzialność autora
PDF/A-1, PDF/A-2, PDF/A-3	PDFACompliance, XMP pdfaid metadata, OutputIntent support, font-embedding enforcement, JavaScript/encryption/annotation/profile guards, and PDF/A-2A / PDF/A-3A smoke outputs validated with veraPDF.	Choose the target level, provide real ICC OutputIntent data, set title/language, embed appropriate fonts, and avoid content outside the selected archival profile.
PDF/UA-1	PDFUACompliance, Tagged PDF root, pdfuaid metadata, /Lang, DisplayDocTitle, structure elements, marked content, role mapping, ParentTree wiring, alternate text and ActualText helpers.	Build meaningful document structure, reading order, heading hierarchy, list/table semantics, and alternative descriptions for real content.
PDF/X-1a, PDF/X-3, PDF/X-4	PDFXCompliance, OutputIntent support, prepress profile guards, and restrictions for interactive or non-print-safe features.	Provide print-appropriate color management, page boxes, and production settings for the chosen prepress workflow.
PDF/VT validation	ValidatePDFVT checks XMP PDF/VT identification, metadata namespace, modification-date consistency, PDF/X base markers, OutputIntent, catalog DPartRoot structure, loadable pages, and page-level DPart coverage.	Use it to audit incoming or produced files; authoring the full variable-data production intent remains the caller's responsibility.

PDF/A Level A enables the Tagged PDF foundation required by the archival profile. It does not automatically advertise PDF/UA-1; HotPDF emits the PDF/UA identity only when PDFUACompliance is explicitly enabled.

Preflight APIs can produce text, JSON, and HTML reports, filter output through saved profiles or built-in presets, aggregate batch results, embed report evidence in a review copy, compare reports, and convert reports into a veraPDF-style structure for downstream tooling.

Aanvullende functiedekking

• OpenType GSUB LookupType 1-8 support, script/language feature selection, Latin standard ligatures, Arabic / Persian / Urdu shaping, Devanagari reordering, and PUA synthetic codepoint emission for font-specific glyphs.
• XFA packet container support, AcroForm /AA trigger wrappers, multiple Unicode fonts in AcroForm /DR, and generated CID-font appearance streams.
• Incremental update saving, multi-signature workflows, signature placeholders, in-process CMS SignedData generation, and long-term validation dictionaries.
• Loaded-document helpers for page-box inspection, bookmark destination lookup, AcroForm field inspection, field value updates, field renaming, field removal, and form flattening.
• Pomocnicze funkcje ładowania, zapisu, walidacji, scalania i porównywania profili preflight, agregacji batch, walidacji raportów osadzonych, osadzania raportów XMP, ukierunkowanej walidacji PDF/VT i ostrożnej naprawy na podstawie raportów preflight.
• PDF 1.3 through PDF 1.7 feature gates, selected PDF 2.0 encryption support, object streams, XRef streams, OutputIntents, transparency groups, soft masks, patterns, shadings, and prepress ExtGState controls.

Wanneer kiest u HotPDF

• Choose HotPDF when your application creates or edits PDF documents and you want a Delphi/C++Builder source-code component rather than a separate PDF service.
• Choose PDFium Component when your primary requirement is PDF rendering, viewing, page rasterization, text extraction, and interactive viewer UI integration.
• Choose the broader Delphi PDF Library package when you need a different API surface for legacy PDFlibPas-style workflows.
