Hi Scott

You could use TARGA to export your data. There is an introduction to 
this format here :
http://astronomy.swin.edu.au/~pbourke/dataformats/tga/

I did write a piece of C++ some years ago that handled the 
reading/writing of TGA images, but I fear it's not terribly well 
coded... And it is badly commented, and in french... I could give a try 
at cleaning it up if you wish, but I think you'd be better off writing 
it yourself ;-) Anyway the format is rather easy to understand.

Hope this helps
