Icon misloaded by the Gimp (1.37 KB, image/x-ico)
2005-06-14 14:56 UTC, Ed Avis 		Details

Description Ed Avis 2005-06-14 14:55:13 UTC 
Version details: 2.2.7 Win32 build
Distribution/Version: Windows XP

The attached .ico file, when you load it into the Gimp, shows a black rectangle
as the top half of the image with some blue stuff below.  This is not correct;
when you view the file in most Windows applications (for example the image
preview in Windows Explorer, or Microsoft Visual Studio) the image is a blue
thing with no black rectangle at the top.  So this is a bug in the .ico input
converter.

Hmm, not sure where to attach the file, but see
<http://membled.com/work/bugs/gimp/misdisplayed.ico>.  You may note that its
display in Mozilla Firefox is different to that in the Gimp - hopefully no need
to start up Windows to verify this bug.

Icon misloaded by the Gimp

This should be a blue icon on a transparent background (and displays as such in
most programs).  But the Gimp misloads it and blacks out the top half of the
image.
Comment 2 Kevin Cozens 2005-06-14 15:52:24 UTC 
The image loads properly in Linux using the 2.2.6 and CVS versions of GIMP.
Comment 3 Ed Avis 2005-06-14 17:56:25 UTC 
Hmm, I found the misloading with both 2.2.2 and 2.2.7 on Windows.
Comment 4 Sven Neumann 2005-06-16 08:59:05 UTC 
Loads fine for me (on Linux).

The icon is recognized as a 8 bpp icon (and, according ot identify, is a image
with a rgba palette). The code in icoload.c seems to assign either A=0 or A=255
in this case.
