graphics modules needed for gif creating

<< < (3/4) > >>

andrea:
Thanks Parham.

Possibly netpbm is able to create gifs. Just reading the user documentation, here is the link:

http://netpbm.sourceforge.net/doc/

With the additional gifsicle utility one should even be able to create animated gifs, link:

Anybody knows one of these programs?

Well, see the problem is that the LZW compression format is copyrighted by someone still, and it's what GIF uses.  Anyone who wants to use gifs has to get the a-ok from the copyright holder.

Luckily, they usually let you (I'm saying this as a programmer, not a scripter... I mean for games, etc.) free of charge.  Further, the patent has ended in the United States, meaning you can use it now - as long as you keep your program with borders.

However, I don't expect to see imagegif working again just yet - and png was made SPECIFICALLY because of these licensing issues. (and also because alpha transparency is good..)

Spaceman-Spiff:
you can use imagemagick to make GIF files
http://www.imagemagick.org/

Aquilo:
but getting your host to install these and other libraries on the
server, thats the trick!
if they have GD already - PNG's are great!

andrea:
Thanks for the informations guys. Get a host who has all those libraries installed: GD2, netpbm, imagemagik.
