Description mlissner 2009-05-10 19:22:25 UTC 
When thumbnails are generated, they should have white backgrounds by default as
opposed to transparency. This is important because not all file managers use
white backgrounds nor should they be required to substitute a background color
for thumbnails. 

I originally filed this bug in gnome-do, which has a black background. Since
most of my OOo thumbnails are for documents with black text, this means that
their thumbnails are almost invariably impossible to see.

The original bug is here: https://bugs.launchpad.net/do/+bug/374388

I'll attach a screenshot of the issue as well.

The spec for thumbnails can be found here, but it doesn't speak to the issue:

Thank you for the patch. I have just integrated it in fwk116 cws.

mav->tm: Please verify the issue. To verify it you can for example store a
document with the cws office, unzip it and open "Thumbnails/thumbnail.png" image
with gimp ( or any other application that recognizes transparent background ).
