The code above doesn't work straight off, but I've managed to get it running (I don't know perl) and now have a working script. Am doing some tweaking and will post my version up when that's done.

[ubuntu-uk] bulk graphics processing problem
hi all, I need several series of numbered icons, from about 1 to 111 in different colours. There must be a way of automating this through the command line using imagemagick, but I haven't found a way of doing so, and my google - fu is giving very poor returns today. Any one got any ideas?
