Quite possibly - fltk provides methods to create "offscreen" render contexts, which I use a fair bit in my app with fltk-1.1.9 to buffer complex scenes so I don't have to re-render the full scene all the time. So you could use such a context, and do all your drawing there. You would then need to get a handle to this and recover the "coloured in" pixel data - this is where you'd have to add some of your own code. A particualr problem is that the pixels will be "coloured in" in whatever order the local rendering context thinks is appropriate, which might not match the remote system, so you might need a bit of RGB <-> BGR swapping or similar...
