If you check the myorthohelp function that called it, you'll already see it is normalized to [0..1] coordinates. But there are some special cases (e.g. sometimes zoomx<>zoomy to get square pixels), vertical inversion etc where not everything is 0..1,0..1 I don't need 3D effects, this is a business app. For an (older) demo based on the code see http://forum.lazarus.freepascal.org/index.php/topic,30556.msg194484.html#msg194484 _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
