THotPDF Advanced Published Properties

이 page는 별도 topic page가 없는 newer 또는 workflow-specific THotPDF published property를 모읍니다. 이 property들은 component surface의 일부이며, 적용 가능한 경우 Delphi, C++Builder 또는 Object Inspector에서 assign할 수 있습니다

Encryption and Version Control

Property	Type	Default	설명
`UseAES256R6`	`Boolean`	`false`	Selects the PDF 2.0 R=6 AES-256 security-handler algorithm when CryptKeyLength is `aes256`. Leave it off for the broader Acrobat 9+ R=5 compatibility path; turn it on for workflows that require the R=6 algorithm
`StrictVersionLock`	`Boolean`	`false`	Controls feature version gating. With the default value, HotPDF can raise Version automatically when a feature needs a newer PDF version. When set to `true`, feature methods that would require a newer PDF version refuse to emit instead of promoting the file

Metadata, Tagged PDF, and Standards

Property	Type	Default	설명
`EnableXMPMetadata`	`Boolean`	`false`	Writes a PDF 1.4+ XMP `/Metadata` stream during EndDoc. The generated packet is built from the document information fields unless `CustomXMP` supplies a caller-authored packet
`CustomXMP`	`AnsiString`	empty	Provides a verbatim XMP packet for the Catalog metadata stream. Use it only when `EnableXMPMetadata` is enabled or when a conformance property enables XMP output automatically
`Lang`	`AnsiString`	empty	Sets the Catalog `/Lang` natural-language tag, such as `en-US`, `de`, or `zh-CN`. It is also used by PDF/UA and tagged-PDF workflows
`EnableTaggedPDF`	`Boolean`	`false`	Enables the tagged-PDF wrapper entries, including `/MarkInfo` and `/StructTreeRoot`. Actual semantic content still comes from structure-element and marked-content calls such as AddStructureElement and page marked-content helpers
`PDFUACompliance`	`Boolean`	`false`	Turns on HotPDF's high-level PDF/UA-1 producer-side defaults, including tagged PDF, XMP metadata, a document language default, and display-title viewer preference handling
`PDFACompliance`	`AnsiString`	empty	Selects PDF/A conformance handling. Supported values include `A`, `B`, `2A`, `2B`, `2U`, `3A`, `3B`, and `3U`. Empty disables PDF/A enforcement
`PDFXCompliance`	`AnsiString`	empty	Selects PDF/X prepress handling. Supported values are `X-1a`, `X-3`, and `X-4`. The property enables matching metadata, version requirements, encryption restrictions, and `Trapped` validation
`Trapped`	`AnsiString`	empty	Writes the PDF/X DocInfo trapped state. Use `True`, `False`, or `Unknown` when `PDFXCompliance` is enabled

Compression and Copy Handling

Property	Type	Default	설명
`CompressionLevel`	`TPDFCompressionLevel`	`clDefault`	Selects the zlib-backed Flate compression level used by enhanced compression paths. Valid values are `clNone`, `clFastest`, `clDefault`, and `clMaximum`
`EnableStructuredContent`	`Boolean`	`true`	version-manager enhanced mode이(가) 현재 PDF 버전에 대해 구조화된 콘텐츠 지원을 활성화 상태로 유지할지 여부를 제어합니다. 이전 문서 모드에서는 자동으로 끌 수 있습니다.
`EnableTransparency`	`Boolean`	`true`	Controls whether transparency-capable output paths stay enabled for the current document mode and PDF version
`EnableOptionalContent`	`Boolean`	`false`	Controls optional-content support for PDF 1.5+ workflows. Version switching can update it through the document feature manager
`DecompressForCopy`	`Boolean`	`true`	When copying from loaded documents, allows HotPDF to decompress source object streams as needed so page-copy and extraction operations can materialize reusable objects
`OriginallyCompressed`	`Boolean`	`false`	Read-only flag set by the loader when source content was originally compressed and had to be decompressed for copy or analysis

Document Information

Property	Type	Default	설명
`Information`	`Boolean`	`true`	Controls whether HotPDF writes the document information dictionary during save. Page extraction and split workflows turn it off on generated output documents when they need a content-only copy

PDF/A Default Color Spaces

RegisterDefaultColorSpace - Maps DefaultGray, DefaultRGB, or DefaultCMYK to an ICCBased color space registered by RegisterICCProfile, so Device color use can be made explicit before PDF/A color checks

UsedDeviceGray, UsedDeviceRGB, UsedDeviceCMYK - document를 build하는 동안 DeviceGray, DeviceRGB 또는 DeviceCMYK content가 사용되었는지 보여주는 read-only flag입니다

Text shaping and compact font output

ShapingFeatures documents the current GSUB/GPOS shaping flags, including typographic feature flags, figure-style flags, complex-script preprocess flags, sfKerning, sfMarkPositioning, sfTibetanShaping, sfMongolianShaping, and sfIndicGSUB

SimpleLatinFonts documents the compact Base14 / WinAnsi path for printable ASCII text

script shaping preprocess methods는 AutoShapeNko, AutoShapeAdlam, AutoShapeHanifiRohingya 및 Thai/Lao, Hebrew, Javanese, Tai Viet, Meetei Mayek, Khmer, Myanmar preprocess flag를 다룹니다. GPOS page는 이제 contextual 및 vertical kerning과 mark-to-ligature placement를 다룹니다

Runtime State

AutoShapeArabic은 text output 전에 producer-side Arabic shaping을 enable합니다. IsHaveSimpleText와 IsEncrypted는 current 또는 loaded document의 simple-text 및 encryption state를 노출합니다

Prepress and Graphics-State Helpers

RegisterSoftMaskState, RegisterTransferFunctionState, RegisterHalftoneType1, RegisterHalftoneState, and RegisterPrintControlState register specialised ExtGState or halftone resources for transparency, transfer-function, screening, overprint, stroke-adjustment, rendering-intent, and flatness workflows

OutputIntent Helpers

AddPDFAOutputIntent와 AddPDFXOutputIntent는 PDF/A 및 PDF/X production을 위한 ICC profile registration과 Catalog /OutputIntents creation을 감쌉니다. 해당 compliance property가 enabled일 때는 EndDoc 전에 사용하십시오

Type 3 Font Glyphs

RegisterType3Font는 caller-defined Type 3 font resource를 만들고 AddType3Glyph는 개별 glyph content stream을 추가합니다. Text를 쓰기 전에 THPDFPage.SetType3Font로 page에서 resource를 선택하십시오

PDF/A Convenience and Associated Files

PDFAConformanceLevel, IsPDFA1Strict, and IsPDFA2OrLater expose the active PDF/A part and conformance branch for caller logic. EnsurePDFAImplementationLimits checks PDF/A-2 and PDF/A-3 implementation limits for metadata strings, /Lang, and page boxes before EndDoc. AddPDFA3AssociatedFile attaches PDF/A-3 Annex E associated files with /AFRelationship; AddFacturXAssociatedFile adds the Factur-X invoice XML, EmbeddedFiles name-tree entry, and XMP metadata for PDF/A-3 invoice workflows; FacturXWarnings reports non-fatal supporting-attachment warnings for those workflows; AddXAdESAssociatedFile embeds caller-generated XAdES XML as an associated file for XAdES-in-PDF workflows
