v1.10.0
Added
- PDF/A-1 conformance (ISO 19005-1, PDF 1.4-based), levels 1b and 1a via
enablePdfA(PdfALevel::A1B)/A1A. Emits a%PDF-1.4header and forbids transparency entirely - an alpha PNG, an SVG with opacity below 1.0, or an SVG mask/filter is rejected with a clear error. veraPDF-validated. - PDF/A-4 conformance (ISO 19005-4, PDF 2.0-based) via
enablePdfA(PdfALevel::A4), plus theA4Fflavour for embedded files (e.g. Factur-X / ZUGFeRD). Emits a%PDF-2.0header, identifies viapdfaid:rev, and omits the deprecated/Infodictionary. veraPDF-validated.
With PDF/A-1, the library now supports the full PDF/A family - parts 1, 2, 3, and 4 are all veraPDF-conformant.
