[bug-gs] colours & encapsulated eps files

[David Pike]

Hi all.

This may or may not be a bug.  The situation I'm in is that I have a
latex document with an encapsulated postscript diagram.  The eps file
has colours and appears to use the CMYK format for them.

AFPL ghostscript/ps2pdf 7.04 converts the .ps file generated by latex
and dvips to a pretty PDF file with no problem.

AFPL ghostscript/ps2pdf 8.53, however, produces a PDF file in which
the colours in the diagram appear to have faded or lost their lustre.
I've tried specifying a number of options for ps2pdf to try to get
the desired effect (ie to keep the colours as they were in the
original postscript file) but I am having no luck.  Sample files
that illustrate what I'm experiencing are available at:

http://www.math.mun.ca/~dapike/trial.pdf  (this is from 8.53)

If this isn't a bug that developed sometime after 7.04, then any
comments or suggestions about how to preserve the colours would
be appreciated.  

Thanks,

- David.
