I've recently built "animation" into the "zimg" program, which normally uses
gd for its output. Before writing the generated image into .gif/.png file,
it is dumping the bitmap into ppm or pgm (ascii) file, which can be
transformed to a movie via animate or convert.

BTW:
	set term gif {animated {delay msec}}
