Thanks imm for responding.I must admit, that was my original guess too, that since such high level drawing is hardly ever needed it would be bloating FLTK if you would have implemented.Congratulations to you guys for such great anti-bloat mentality and for keeping FLTK small and fast as it's supossed to be! And yes, of course I will use FLTK for the GUI part(widgets only).I just wanted to know if it would have been a waste of my time to implement those drawing functions on my own or where you guys planning to implement them directly in FLTK.But now I know. You say that I shouldn't implement them on my own, but neither use FLTK's own, instead I should use Cairo or AGG or even OpenGL.Now I don't know about OpenGL since it's vector graphics though I know it has some raster capabilities too, but my editor is a raster editor just like Krita or Gimp.I will look into those libraries. Thank you again for clarifying things so now I now what I have to do. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
