Manolo, In case it helps, there's a very handy explanation of why the half- pixel thing makes sense in an anti-aliased context, in the Cairo docs. I know quartz is not cairo, of course, but the reasons hold true... I think it is probably a FAQ, as it is not intuitive for people used to a pixel based rendering scheme. _______________________________________________ fltk-dev mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk-dev
