Is this the right link - "Display Arbitrary Data as an Image"? I don't understand, what this should tell me, because my problem is to get the Fl_Offscreen image array and I didn't found Fl_Offscreen mentioned at all: >>./FL/win32.H:134:typedef HBITMAP Fl_Offscreen; >>./FL/x.H:95:typedef ulong Fl_Offscreen; There is a HBITMAP and ulong, how can I use this to get the image array? It's the part "just read back and repack". ;o) _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
