Description Raphaël Jacquot 2007-05-21 14:58:42 UTC 
instead of the colored pictures, we can only see useless black blocks
Comment 1 Jeff Muizelaar 2007-05-25 11:46:24 UTC 
I can't reproduce. What viewer are you using and what version of poppler?
Comment 2 Jeff Muizelaar 2007-05-25 12:01:08 UTC 
Nevermind I can reproduce. Looks like it might be a color space problem with the cairo backend.
Comment 3 Jeff Muizelaar 2007-05-25 13:28:23 UTC 
Looks like the problems is in GfxImageColorMap::GfxImageColorMap around line         3420 where we build the byte_lookup table. When doing so we severly overflow and probably don't build a useful table.
