I am reading. Quartz uses floating point numbers to calculate lines. The plastic scheme is composed by drawing a bunch of lines so that they overlap and draw the resulting object. What you (and me too) are seeing is an imprecision that made one line move a bit to the right, which would not matter in integer math, but generates this artefact if using floating point. Patching coordinates in the plastic box drawing code will temporarily fix this, but better would be some pixel-exact drawing on all platforms (or using pixmaps instead of drawing lines and arcs). ---- http://robowerk.com/ _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
