Thanks a lot for forwarding my email to the boost GIL list. I will check it
out.
What I meant by conversion, however was primarily converting an image to
negative and greyscale. As you may already know, the two pf them are pretty
similar and OpenMP has shown how incredibly fast the process can be using
more threads. I just feel GIL would benefit a lot from using parallel
programming.
