Criação e validação PDF/X-6

HotPDF supports complete, externally profiled, and N-colourant PDF/X-6 exchange workflows over PDF 2.0

Profiles

`PDFXCompliance`	`THPDFPDFX6Profile`	Output profile
`'X-6'`	`px6Complete`	Embedded ICC profile through `DestOutputProfile`
`'X-6p'`	`px6External`	External gray, RGB, or CMYK ICC profile through `DestOutputProfileRef`
`'X-6n'`	`px6NChannel`	External N-colourant profile plus matching `ColorantTable`
Detected from the document	`px6Automatic`	Uses the producer setting or loaded XMP identification

Complete profile example

PDF.Version := pdf20;
PDF.PDFXCompliance := 'X-6';
PDF.Title := 'Press-ready artwork';
PDF.Trapped := 'False';
PDF.BeginDoc;
PDF.CurrentPage.SetTrimBox(0, 0,
  PDF.CurrentPage.Width, PDF.CurrentPage.Height);
PDF.AddPDFXOutputIntent('CGATS TR 001',
  'Document printing condition', ICCStream, 4, 'DeviceCMYK');
PDF.EndDoc;

EndDoc runs fail-closed validation for all three PDF/X-6 profiles before serialization

Output-intent scope

AddPDFXOutputIntent adds one embedded Catalog-level profile for the complete profile
AddPDFX6PageOutputIntent adds an embedded profile to one page
AddPDFX6ExternalOutputIntent adds an external profile reference at Catalog scope with PageIndex=-1 or at page scope with a zero-based index
A page-level OutputIntents array overrides the Catalog array for that page
Each effective scope must contain exactly one PDF/X intent

Page boxes

The validator resolves inherited MediaBox e CropBox, checks direct BleedBox, TrimBox, and ArtBox values, and requires exactly one finished-page box per page

Every rectangle must contain four finite ordered coordinates
CropBox, BleedBox, and the finished-page box must stay inside MediaBox
TrimBox e ArtBox are mutually exclusive

Exchange constraints

One bounded graph traversal checks the profile identification and exchange structures while deduplicating shared resources by object identity

PDF 2.0 header, XMP profile marker, dates, title, trapped state, trailer ID, and absence of encryption
Action types, action chains, destination arrays, AcroForm state, and field additional actions
Printable visible annotations with fixed normal appearances and no PrinterMark or TrapNet subtype
Embedded font programs, Type 0 descendants, graphics-state value types and ranges, and resource XObjects
Disallowed page production-step data and alternate-presentation or viewer-preference Catalog data

Structured diagnostics

ValidatePDFX6 devolve THPDFPDFX6ValidationIssues, an array of THPDFPDFX6ValidationIssue records whose THPDFPDFX6IssueSeverity identifies warnings and errors

Each issue includes a stable code, standard clause, object path, object number, zero-based page index, and message

THPDFPDFX6ValidationOptions independently bounds objects and issues and can isolate output-intent, page-box, exchange, font, or annotation checks
