(note - not only acrobat, but also ghostscript understands the initial pdf format sufficiently to convert it in a pdf/a which displays correctly using MuPDF based viewers. So we are probably working around a MuPDF bug here. Anyway...)
@kaestli Does your PDF/A export with Acrobat maintain the same original quality and size of the file ?
I attempted to use ghostscript to convert it to PDF/A, but unfortunately, this process rasterizes the first page, making the text no longer searchable and selectable (see ria_report_ghostscript.pdf). Any clue ?
After investigation:
The problem has been resolved on the NAZ web page by rasterizing the entire page (PDF to PDF/A with ghostscript), which works for this use case, but not for consultation purposes
There is no easy solution to achieve consistent PDFs across all viewers. Similar issues have already been raised for these specific PDF viewers (Evince, MUPDF), but as mentioned, the workarounds are not straightforward.
Online consultation (HTML) is the recommended approach and the safest in terms of compatibility. If PDF consultation is needed, Adobe Acrobat, recent Mac document viewer, and browser viewers are the way to go. We should eventually advise users not to use Evince and MuPDF
Very accurate problem description from Philipp:
Acceptance Criteria
Pdfs generated using the
web-pdf-generator
application are already converted to the PDF/A standard and are correctly displayed using eg. the MuPDF viewer.
