How to generate NON-transparent PDFs with PDFReactor?

Question

I'm using PDFReactor 5 in Java to generate PDF files. The generated files must conform to the PDF/A1-a standard which does not allow transparency.

I use the PDFA conformance mode in PDFReactor like so pdfReactor.setConformance(PDFreactor.CONFORMANCE_PDFA); but the validator at http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx says my generated files are not valid PDF/A1-a since they contain transparency.

Any idea how one can configure PDFReactor to generate an opaque document?

Answer 1

The way to generate is the one you used, so it's correct to set:

pdfReactor.setConformance(PDFreactor.CONFORMANCE_PDFA);

I have seen that pdfreactor5 generates pdf not fully compatible with the pdf-a specs (transparency and others).

Upgrade to pdfreactor6 .

After the upgrade my pdf was validated against http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
