273358 - Copy & Paste does not respect transparency of GIF-images

Status: RESOLVED DUPLICATE of bug 249032

(Firefox :: Shell Integration, defect)

Description

[Gregor Rosenauer]

Copy&Pase of images does not work for GIF-images that use transparency (GIF87a).

When copying the image of the given URL to the clipboard (rightclick-menu->"Copy
Image") and pasting it anywhere, you always get a black background (the image at
the given URL is totally black as also the drawing itself is black).

I do not know the specifics of the Windows clipboard and how it handles images,
but if transparency is a problem, at least a white background should be used,
sothat the image appears as in the browser.

The image is taken from:
http://edocs.bea.com/manager/mgr20/intref/overview.htm

I tried this with 2 GIF-images and got the same result (black background).
PNG transparency seems to work.

InternetExplorer produces the expected result (even;-).

This bug still exists in the latest Firefox build. It's annoying, as IE does
this correctly.
