bitmaps display in acroread and evince (47.20 KB, image/png)

Description Marcus Granado 2007-06-04 18:37:02 UTC
It seems that this lack of functionality is affecting pdf viewers/backends such as poppler (see bug #5589):

See how this manifests itself visually:

The problem is present in latest cairo 1.4.6 / poppler 0.5.4 / evince 0.9.0.
Comment 1 Pablo Rodríguez 2007-07-15 06:16:13 UTC
Using cairo 1.4.10, poppler 0.5.9 and evince 0.9.2, I think I get even worse results (see atached image acrobatvsevince.png).

I hope it helps,

Comment 3 Pablo Rodríguez 2007-07-21 02:38:38 UTC
I guess the bug above was wrong reported, because the bug might have been introduced in poppler-0.5.9 (see bug 5589 for that).
