Package: ghostscript
Version: 8.70~dfsg-2
Severity: normal
Certain ps/eps files produced by python-matplotlib are not translated
properly to pdf by ps2pdf/eps2pdf. In particular, negative numbers as
labels on a color bar end up as two dashes in the pdf (as viewed by
both xpdf and evince). Xpdf also complains about the translated pdf
file. The original ps/eps files display perfectly with gv and evince.
This problem occurs only with ps2pdf/eps2pdf in squeeze. The lenny
versions of these scripts yield translations which present properly in
xpdf etc.
I am including a short python script which produces the ps and eps
files which exhibit the problem. Select the ps or eps output when the
matplotlib display window pops up and then translate the file to
pdf using ps2pdf or eps2pdf. I can provide the original ps and the
translated pdf files done on both lenny and squeeze if desired.
