THotPDF.ValidatePDFX6 Method

Runs bounded PDF/X-6, PDF/X-6p, or PDF/X-6n validation over the current producer or loaded object graph without mutating the document

名前	目的
`Options`	Selects the profile, traversal budgets, and independently switchable validation groups
`Issues`	Receives stable structured diagnostics in traversal order

戻り値

Returns True only when no x6isError diagnostic remains

使用上の注意

THPDFPDFX6ValidationOptions.Default selects px6Automatic, x6rsResolvedErrata2025, a 1,000,000-object budget, a 1,024-issue budget, 64 MiB of decoded data, 4,000,000 content tokens, and all validation groups

Field	Purpose
`Profile`	Uses `THPDFPDFX6Profile` to select automatic, complete, external, or N-colourant validation
`RuleSet`	Selects ISO 15930-9:2020 as published or with resolved errata through 2025-11-11
`MaxObjects`	Bounds indirect and reachable-object traversal
`MaxIssues`	Bounds retained diagnostics and emits a stable limit issue when exhausted
`MaxDecodedBytes`	Bounds cumulative decoded ICC profile and content-stream bytes plus bounded JPX header input
`MaxContentTokens`	Bounds cumulative parsed operators, operands and nested array work items before unbounded arrays can form
`CheckOutputIntents`	Checks effective Catalog or page output intents and embedded or external profiles
`CheckPageBoxes`	Checks inherited MediaBox and CropBox plus direct BleedBox, TrimBox, and ArtBox geometry
`CheckExchangeConstraints`	Checks actions, forms, graphics state, XObjects, optional presentation data, and related exchange restrictions
`CheckEmbeddedFonts`	Checks embedded font programs and Type 0 descendants
`CheckAnnotations`	Checks annotation subtype, flags, and fixed normal appearances
`CheckPaintedColourSpaces`	Interprets actual path, text, image, shading, pattern, glyph, soft-mask, and appearance paints and validates their effective colour spaces
`CheckOverprint`	Checks stroking and nonstroking overprint state, mode 1 applicability, and combined-paint interactions
`CheckTransparency`	Checks alpha, blend modes, transparency groups, soft masks, and combined fill-and-stroke compositing

THPDFPDFX6IssueSeverity distinguishes warnings from errors
Each THPDFPDFX6ValidationIssue carries a stable code, clause, rule set, rule revision, object path, object number, zero-based page index, and message
THPDFPDFX6ValidationIssues preserves deterministic discovery order for repeatable CI output
The THPDFComplianceFindings overload maps the same pass to the shared PDF/X-6 finding profile without extra graph traversal
Page-level output intents override Catalog scope as required by PDF 2.0
Content, ICC, JPX header and Type 3 structure work are cached by object identity, while context-sensitive graphics state is evaluated independently for every invocation
Validation is non-mutating and fails closed when object, issue, decoded-byte, token, recursion, or graphics-state-stack limits are exhausted
