What I have done before is saved the bitmap to disk and then used the netpbm tools, called from within lua, to convert the bitmap to some other form. Netpbm is a free set of command line tools for performing just about any graphics format conversion. You can download it at http://sourceforge.net/projects/netpbm/`
