PdfVTConformance property

この API エントリでは識別子、シグネチャ、コードブロック、PDF 用語を元の表記のまま保持します。

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

PdfVTConformance is the lighter-weight counterpart to ValidatePdfVT: it returns the detected conformance level directly without materialising the full issue list.

Possible values:

• pvcNone — the document carries no PDF/VT markers.
• pvc1 — PDF/VT-1 (ISO 16612-2:2010, single-file, PDF/X-4 base).
• pvc2 — PDF/VT-2 (ISO 16612-2:2010, file-set, PDF/X-4 / X-4p / X-5g / X-5pg base).
• pvcUnknown — an XMP pdfvtid marker is present but the version string is unrecognised, or the document is inactive.

Use PdfVTConformance for routing decisions in variable-data print workflows ("does this batch need DPart augmentation?") and for surfacing a single status string in the UI. When the caller also needs to enumerate the specific issues that broke conformance, use ValidatePdfVT instead.

• Returns pvcUnknown when Active is False.
• The property re-runs ValidatePdfVT on every read — cache the value if you query it more than once per file.
• Marker presence does not imply structural compliance. PDF/VT additionally requires a /DPartRoot Document Part Hierarchy (§6.5) and full PDF/X-4 content-level rules; neither is checked here.
