Nope, due to patent issues we can not add it.

Hello ,

I've got a patch (originally ported from old version GD) which adds GIF write support to bundled libGD. Is there any chance to accept it to core ?
I've been testing it for quite long time with 4_3 and HEAD and it works ok for me.

Hello Derick,

DR> Nope, due to patent issues we can not add it.
Action of the patent on GIF was not expired ?

http://lpf.ai.mit.edu/Patents/Gif/Gif.html
The United States LZW patent expired on June 20th, 2003..
According to Unisys, the counterpart Canadian patent expires July 7, 2004, the counterpart patents in the
United Kingdom, France, Germany and Italy expire June 18, 2004, and the Japanese counterpart patents expire June 20, 2004.

It's not July 7th yet, is it?

The patent expires on June 18th of this year so just under a month and 
it can be added again.

Err..

Just saw the rest of the thread so I hope its going to be added again as 
of the last patent expiry, or could the patch possibly appear in the 
documentation until the last one expires?

Scott
