PdfRConformance property

Esta entrada API conserva identificadores, firmas, bloques de código y términos PDF en su forma original.

Read-only PDF/R conformance level of the currently open document, without needing to call ValidatePdfR explicitly.

PdfRConformance is the lighter-weight counterpart to ValidatePdfR: it returns the detected conformance level directly without materialising the full issue list. The property is a thin wrapper that calls ValidatePdfR and returns the Conformance field, so the result is always the same value the validator would report.

Possible values:

• prcNone — the document carries no PDF/R version marker.
• prc1 — PDF/R-1 (ISO 23504-1:2020) marker %PDF-raster-x.y found in the file.
• prcUnknown — document is inactive or parsing failed.

Use PdfRConformance for routing decisions in document capture / archival workflows ("does this scan claim to be PDF/R?") and for surfacing a single status string in the UI. When the caller also needs to enumerate the specific issues that broke conformance, use ValidatePdfR instead so the parse runs only once.

• Returns prcUnknown when Active is False.
• The property re-runs ValidatePdfR on every read — cache the value if you query it more than once per file.
• Marker presence does not imply structural compliance. PDF/R has strict per-page Contents / MediaBox / filter / object-stream rules that PdfRConformance does NOT check. Use ValidatePdfR for the full file-format-level issue list and pair with a TWAIN Working Group PDF/R validator for content-level verification.
