I'd probably render the whole lot in an fl_offscreen, to be honest, then in the display widget's draw method, I'd use fl_copy_offscreen(int x, int y, int w, int h, Fl_Offscreen osrc, int srcx, int srcy) to copy the interesting parts of the offscreen onto the display. > I planned to cut the tileset into > several images and then put them into buttons.

I'm not sure I'd bother with Fl_Image, though it can probably work for you: Here are a couple of howtos that might help you manipulate the image data. http://www.fltk.org/articles.php?L466 http://www.fltk.org/articles.php?L468 SELEX Galileo Ltd Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
