It is possible yet with the libgd.org's gd. However the code I wrote
for the php's libgd can be easily ported to any C application (or
scripts for that matter). You can find it in php's cvs (or source
releases):

http://cvs.php.net/viewvc.cgi/php-src/ext/gd/libgd/gd.c

See the end of the file. It is was imagefilter and imageconvolution use.
