Description:
------------
I've made a few tweaks to GD to get it to support partial 
palette transparency better.

The (now fixed) problem was that if a partial transparency 
palette image was copied over any background, the palette 
image became opaque.

Which are you trying to solve?

Please post a link to script to reproduce your problem, with the expected image and what you get.

I've upped an example at:
http://pricepages.org/temp/grad.zip

Included is the source image, test script, and two output 
files. The test composites the source image grad.png (a 
alpha gradient) onto a blank white canvas.

test.orig.png is what the output should currently look like.

test.patch.png is how it looks after the patch.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.

Ok I got the problem. I did not use your patch, it modifies the wrong of the code, breaking other features. However thanks you to have tried :)

Fixed in 5.2 and HEAD.
