PdfXConformance property

이 API 항목은 식별자, 시그니처, 코드 블록, PDF 용어를 원래 형태로 유지합니다.

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

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

Possible values:

• pxcNone — the document carries no PDF/X markers.
• pxc1a — PDF/X-1a:2001 (ISO 15930-1) — CMYK + spot only, no transparency, PDF 1.3 / 1.4 base.
• pxc3 — PDF/X-3:2002 (ISO 15930-3) — adds RGB / Lab / ICC-managed color, no transparency, PDF 1.4 base.
• pxc4 — PDF/X-4:2010 (ISO 15930-7) — adds transparency, layers, JPEG2000, OpenType fonts, PDF 1.6 base.
• pxcUnknown — an XMP pdfxid marker is present but the version string is empty or doesn't match any of the recognised levels.

Use PdfXConformance for routing decisions in print workflows ("does this advertisement need preflight before submission?") and for surfacing a single status string in the UI. When the caller also needs to enumerate the specific issues that broke conformance, use ValidatePdfX instead so the parse runs only once.

• Returns pxcUnknown when Active is False.
• The property re-runs ValidatePdfX on every read — cache the value if you query it more than once per file.
• Conformance detection is structural (XMP marker presence + Info /GTS_PDFXVersion + OutputIntent existence). Content-level violations (unembedded fonts, transparency in PDF/X-1a / PDF/X-3, JavaScript, visible annotations, etc.) are NOT detected here. Pair with callas pdfaPilot or Ghent PDF Workgroup Output Suite for a full PDF/X preflight.
