RMagick gives you a drawing API into an in-memory image,
which you can save to a file in numerous formats. You can
also access the pixel array and map them to a Pixbuf to
display in a ruby-gtk application. This approach might be
more suitable than TkCanvas if your main goal is to generate
image files (rather than display images).
