PdfEConformance property

此 API 條目保留識別符號、簽名、程式碼塊和 PDF 術語的原始形式。

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

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

Possible values:

• pecNone — the document carries no PDF/E markers.
• pec1 — PDF/E-1 (ISO 24517-1:2008) identifier pdfe:ISO_PDFEVersion with a non-empty value was found in the XMP metadata stream.
• pecUnknown — an XMP pdfe marker is present but the value is empty / unrecognised, or the document is inactive.

Use PdfEConformance for routing decisions in engineering workflows ("does this drawing need to go through the PDF/E promotion pipeline?") and for surfacing a single status string in the UI. When the caller also needs to enumerate the specific issues that broke conformance, use ValidatePdfE instead so the parse runs only once.

• Returns pecUnknown when Active is False.
• The property re-runs ValidatePdfE on every read — cache the value if you query it more than once per file.
• Conformance detection is structural (XMP marker presence + Info /ISO_PDFEVersion entry). It does not catch content-level violations such as unembedded fonts, prohibited XObject types, or XFA forms. Pair with callas pdfaPilot or axesPDF for a full PDF/E validator.
