Subject: image creation

Hi...

Im pondering how to best create an image from a Ruby script.
1) a x*y size String comes to mind
   easy manipulation
2) dump it out to a .pgm file
3) call pgm2jpg, pgm2png or something like that
4) serve link to file

For small images a "keep in memory" and call libjpg directly approach
comes to mind, for large images maybe via mmap?

Anyone ever did such things, pointer to example code?

thanks,
Martin
