Description:
------------
I submitted this to the maintainer of GD and he said 
that there is a patch for this coming in GD 2.16. It is 
a somewhat obvious bug, so I won't waste time coding up 
examples (if you still want examples, say so...).

In gd.c (ext/gd/libgd/gd.c) line 258 says "ad = im-
>blue[i] - a;" but it should say "ad = im->alpha[i] - 
a;".

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
