SetPDFXMode

Compliance

Description

Selects the PDF/X conformance mode the writer enforces while a document is authored (ISO 15930)

Syntax

Delphi

Function SetPDFXMode(NewMode: Integer): Integer;

Parameters

NewMode	1 selects PDF/X-1a:2003, 2 selects PDF/X-3:2003, 3 selects PDF/X-4, 4 selects PDF/X-6 complete exchange, 5 selects PDF/X-6p process-colour partial exchange and 6 selects PDF/X-6n n-colourant partial exchange

Return value

1 when the mode was selected, 0 for an invalid mode, a loaded document (the mode applies to newly created documents only) or a save version explicitly locked above the part base

Remarks

The mode writes the pdfxid XMP edition identification, configures the relevant output-intent workflow, declares /Trapped and bases the save version on the part: PDF 1.4 for X-1a and X-3, PDF 1.6 for X-4 and PDF 2.0 for the PDF/X-6 family

PDF/X-6 complete exchange uses the bundled sRGB profile by default so the embedded ICC payload and its three-component declaration agree; use LoadOutputIntentProfile to supply another Gray, RGB or CMYK print profile

PDF/X-6p and PDF/X-6n do not create an embedded profile; call SetOutputIntentProfileReference with a process-colour or n-colourant ICC file and one or more retrievable URIs before saving

The PDF/X-6 family may also use page-level output intents created with SetPageOutputIntent; an explicit page intent takes precedence over the document intent, and preflight requires every page to resolve to one of them

Authoring-time gates reject DeviceRGB and ICCBased colour spaces under X-1a, transparency and optional content outside X-4, document-level JavaScript, file attachments, encryption, LZWDecode images and non-embedded fonts in every mode

PDF/X-6 permits JavaScript only when a user directly activates a Link annotation, limits named actions to page navigation, and rejects unsafe actions such as Launch, ResetForm, ImportData, Hide and SetOCGState

At save time every page receives a TrimBox (defaulting to its MediaBox), annotation Print, Hidden, Invisible, NoView and ToggleNoView flags are normalised, the AcroForm NeedAppearances flag is set to false and the trapping state is declared

PDF/X-6 preflight also validates fixed annotation appearances, button appearance states, AcroForm and signature widgets, XFA and NeedsRendering exclusions, action chains and catalog, page, screen, widget and field action restrictions
