Well i think it should works well! In fact i use libplot to "export" a chemical structure formula from ram memory to (primarly) a postscript file. Postscript is the preferred format because it integrates well with latex and some scientific magazine are happy to get the image for a paper in postscript... I was looking around at the documentation of cairo and it have a postscript and PNG backend...that's exactly what i need! Moreover i think i can remap the libplot's functions my application call with the cairo's ones easily as i use a singleton for a "plotter" object that is used by the rendering function...so i think i can just make the singleton a cairo's surface pointer ...what i find frustrating is that the pango documentation appear a little bit dispersive. I think this will require a lot of work however! :-( Bye! C. _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
