Description Jonathan Underwood 2009-01-19 15:03:05 UTC 
Description of problem:
If I take a pdf file which has some transparency in it and use pdftops to convert it to a postscript file, I lose the parts of the image with transparency. Same thing happens if I print to a ps file with evince (which is presumably using the same libpoppler code). Test files attached below.

Version-Release number of selected component (if applicable):
poppler-glib-0.8.7-1.fc10.x86_64
poppler-0.8.7-1.fc10.x86_64
poppler-utils-0.8.7-1.fc10.x86_64
poppler-qt4-0.8.7-1.fc10.x86_64


How reproducible:
Everytime

Steps to Reproduce:
1.pdftops FranckCondon.pdf
2.
3.
  
Actual results:
FranckCondon.ps doesn't contain the background grid

Expected results:
FranckCondon.ps should contain the background grid

Additional info:
FranckCondon.pdf was created in inkscape and exported to pdf using the cairo backend.
