Hello Aspose,
there’s a Maven project attached, which kind of inverts or blackens the source PDF (provided in src/main/resources). Please add a license file to src/main resources and run the main class BlackDoc. It iterates over the members of the PdfFormat enum and produces an out-*.pdf file for each one whose name starts with “PDF_A”.
Thanks in advance, best regards,
Otto
