Are there other FLTK allows to draw to an offscreen buffer. glDrawPixels() or if you need shaders, then better glTexImage2d and friends can bring them into OpenGL. Search for fl_create_offscreen(), fl_begin_offscreen, fl_read_image, fl_end_offscreen. Some not so self contained code for a rough idea[1]. kind regards Kai-Uwe [1] http://www.oyranos.org/scm?p=oyranos.git;a=blob;f=src/examples/image_display/Oy_Fl_Group.h;h=0e0cfd77759f198fd8bf7f7c3fb63009870750e3;hb=HEAD#l196 _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
