Description Patrick Pletscher 2006-03-08 05:01:33 UTC

See the attached files. They both render fine in gtk-splash-test, but don't show
some elements in gtk-cairo-test.

I think they both suffer from the same problem (however I'm not entirely sure).
The bugs were originally reported against evince
(http://bugzilla.gnome.org/show_bug.cgi?id=173143 and
http://bugzilla.gnome.org/show_bug.cgi?id=159494), but we think that this bug is
a poppler-bug.

It is maybe related to poppler bug
https://bugs.freedesktop.org/show_bug.cgi?id=4330, but there gradients get
displayed (although in a awkward fashion). Here the elements don't get displayed
at all...

The problem with cube image is that CairoOutputDevice does not implement
drawMaskedImage.

Comment 4 Jeff Muizelaar 2006-04-12 16:49:21 UTC

Drawing of the 3 cubes pdf is now fixed in cvs. I am making a gamble that the 
red dots problem is really #5561. Changes to fix #5561 are available at:

 git://git.cairographics.org/~jrmuizel/cairo dashing

Note, I haven't actually tested that the red dots problem is the same as #5561.

Comment 5 Jeff Muizelaar 2006-04-13 09:46:25 UTC

The red dot problem isn't exactly #5561. Instead it is a problem with cairo's 
rendering of zero length lines.

Comment 6 Jeff Muizelaar 2006-09-20 17:21:49 UTC

This should be fixed with cairo 1.2.4
