compatibility "1.3" writes a %PDF-1.3 file (its XMP metadata says 1.3 too) without transparency: a copy of the document is flattened first with flattenerPreset (stored with PDF presets; empty is High Resolution) and the flattener options over it, see-through image pixels counting as transparency and rasterized areas clipped to their regions so no soft mask is needed. Page groups are left out and the writer refuses a file that would still have transparency. PDF/X-1a and PDF/X-3 share this path (their version is now PDF 1.3; 1.4 is still accepted and written as 1.3), and with it the preset, the header and metadata code and the transparency check. Passwords at PDF 1.3 encrypt with 40-bit RC4 (revision 2). The Save PDF dialog lists PDF 1.3 and picks the flattener preset under Advanced. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |
