If you mean the round corners for rectangle select you can study the implementation of gimp_channel_combine_ellipse_rect() here: http://git.gnome.org/cgit/gimp/tree/app/core/gimpchannel-combine.c#n202 It's not based on general super-sampling or antialiasing/smoothing techniques, instead it's based on trigonometry and the geometry for each individual pixel. / Martin -- My GIMP Blog: http://www.chromecode.com/ _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
