I can't seem to find a way to return the RGB value at a specific pixel. It's becoming quite a annoying, as I can set one. Am I just daft and am not seeing it, or is there a more arcane way of doing it?

Ah, I'm not sure. Just a random guess; maybe the same call that sets a pixel will get one if you don't specify a value? You come across that sort of thing in Perl modules occasionally. I've not used Image::Magick, but things like that certainly crop up, for example, in CGI.pm. Hope this helps!
