Bug#801395: libgs9-common: Unable to produce a PDF/A on Debian 8

[Brian Potkin <claremont102@gmail.com>]

Package: libgs9-common
Version: 9.06~dfsg-2+deb8u1
Severity: wishlist


I used the sample command line at

  http://ghostscript.com/doc/current/Ps2pdf.htm#PDFA

and followed the advice given in

  http://bugs.ghostscript.com/show_bug.cgi?id=691448

to change the line

  /ICCProfile (ISO Coated sb.icc)   % Customize.

to

  /ICCProfile (/usr/share/color/icc/ghostscript/srgb.icc)   % Customize

The result is

  brian@desktop:~$ gs -dPDFA=1 -dBATCH -dNOPAUSE  -sDEVICE=pdfwrite -sColorConversionStrategy=/RGB -sOutputFile=out.pdf $HOME/PDFA_def.ps in.pdf

Then I replaced

  [/_objdef {icc_PDFA} /type /stream /OBJ pdfmark
  [{icc_PDFA} <</N systemdict /ProcessColorModel get /DeviceGray eq {1} {4} ifelse >> /PUT pdfmark
  [{icc_PDFA} ICCProfile (r) file /PUT pdfmark

in $HOME/PDFA_def.ps with the code from the corresponding section of the
PDFA_def.ps file in libgs9-common (9.16~dfsg-2). in.pdf is now processed
to out.pdf.

It would be nice if a point release of Debian 8 could incorporate this
fix. Or is it not possible or desirable to alter a package in stable in
such a way?

Regards,

Brian.
