Description Dmitri A. Sergatskov 2004-06-17 02:41:12 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)
Gecko/20031114

Description of problem:
eog cannot display transparent png images. The background is checkered
black/gray. I cannot verify that image is 100% conformant PNG
(it is created by gnuplot 4.0), but mozilla and "display" (from
ImageMagic) display it correctly.   
I suspect this is fault in one of the libraries since
kview and GQview fail as well. 

Version-Release number of selected component (if applicable):
eog 2.4.0

How reproducible:
Always

Steps to Reproduce:
1.Save the image from URL to the disk
2.open it in eog
3.
    

Actual Results:  Background is checkered black/gray.

Expected Results:  Transparent background

Comment 2 Peter van Egdom 2004-06-18 21:16:14 UTC
This is not a bug, but a feature. Both "eog" (and, for example, the
Gimp) use the checkered black/grey background to display the
transparant part of the picture. In "eog" you can use the preferences
screen to specify what to do with the transparant part of the picture.
