The Problem

Trying to convert an ordinary PDF file to PDF/A, I got the following error message after a short time:

...in getcolor raise ValueError(msg) ValueError: cannot add non-opaque RGBA color to RGB palette

I attached the error message and the stack trace in the relevant log output.

If you need more information, I will try to help.

Hey @bjoern-vh, could you please share a reproducible example so we can take a look at it?

bjoern-vh commented 1 month ago

Yes, of course. Here a single test page that throws that error message.

test.pdf

Thanks a lot in advance :+1:

sbplat commented 1 month ago

Here's the converted version of your pdf in case you need it. I'll push a fix for it now. test_PDFA.pdf

Frooodle commented 1 month ago

Will do another release tonight or tomorrow morning with this fix
