(Apologises if you already received this email - it didn't show up in
the archives, so I subscribed to the list and am resending now.)
I hope this is the right mailing list for this kind of questions; it
seemed like the best match I could find on
I'm wondering about ghostscript's support of PDF/A.
According to bug #690046 "Ghostscript doesn't produce valid PDF/A-1B
files", there's now a patch to make ghostscript support PDF/A-1B. I
saw in 8.64's "changes.html" that this patch is in the latest release.
Does this mean that ghostscript 8.64 will always generate valid
PDF/A-1B PDF's, if used with the commandline params seen in bug
gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite \\
-sOutputFile=MY_OUTPUT_FILE_TO_BE_IN_PDFA.pdf -c .setpdfwrite \\
-dCompatibilityLevel=1.5 -r600 \\
-dEmbedAllFonts=true -dSubsetFonts=true -dMaxSubsetPct=100 \\
-dAutoFilterColorImages=false -dAutoFilterGrayImages=false \\
-dDownsampleGrayImages=false -dDownsampleMonoImages=false \\
-dProcessColorModel=/DeviceCMYK -dUseCIEColor \\
There are several other commandline examples in this bug, but they
don't look at lot like this one - is there one which is more correct?
Are there any params which will *always* be correct, no matter what
the original postscript file looks like, or are there any params which
depend on the original postscript file?
Further, while my understanding of PDF/A is rather limited, it seems
to me like A-1B is only a subset of A-1A. Any plans to support
PDF/A-1A in ghostscript? If so, is there an ETA for this?
Sorry about all the questions...
Many thanks and best regards,
