Package: ghostscript
Version: 9.04~dfsg-3
Severity: wishlist
Tags: patch

Dear Maintainer,

Along with the other ps2pdf* scripts, it would be very helpful to have a 
script to create PDF/A. Attached is an attempt at creating such a 
script.

Attachments:

1. ps2pdfa script, modelled on the others.

2. A patch file that makes minor changes to ps2pdfwr to allow ps2pdfa to 
provide an additional input file. It needs this in order to provide a 
PDFA_def file.

3. Two PDFA_def files: one for each of DeviceGrey and DeviceCMYK, based 
on /usr/share/ghostscript/9.04/lib/PDFA_def.ps. The only difference is 
that the /ICCProfile is set to one of 
/usr/share/ghostscript/9.04/iccprofiles/default_(grey|cmyk).icc

I have not done much sh programming, so there may be improvements that 
can be made.

It works, except for an error message which seems to be related to file 
permissions, but I can't figure out what is wrong. It works if I comment 
out the line in the PDFA_def file:

[{icc_PDFA} ICCProfile (r) file /PUT pdfmark

But with that line gone, I don't think it creates a valid PDF/A 
document.

Besides fixing this issue, there is one other todo. The title is 
supposed to be set in the PDFA_def file. I think doing this is beyond 
what I am comfortable doing in sh. Should I generate a tmpfile 
containing a customized PDFA_def with the title?

I would appreciate your assistance with this or your referral to a 
better forum to present this feature request.

Thank you,
Liam Morland

Thanks!  Upstream response:

For the time being I don't think it's worth carrying this as a
Debian-specific patch, so closing.

Please do keep us posted, though, and e.g. if several packages end up
needing this then we'll probably be happy to reconsider.  Or maybe
it's worth rearranging into an example for documentation.
