HPDFConvertHeadlessToPDFA4File

function HPDFConvertHeadlessToPDFA4File(Document: THPDFHeadlessDocument;
  const FileName: string; const Options: THPDFHeadlessArchivalOptions): THPDFHeadlessArchivalResult;

Rasterise the loaded pages into a fresh unencrypted PDF/A-4 file with actual XMP, document identifiers and an embedded sRGB output intent

The source graph remains unchanged, source/destination aliases are rejected, and bounded same-directory staging preserves the destination should failure or cancellation occur

Visible annotation appearances must be renderable; signed inputs require explicit invalidation permission, and text/vector preservation lies outside this raster API
