From: gg@xxxxxxxxxxx Thanks for your ideas. If you want to play around with Lanczos, you might benefit by looking over the enhancement requests and bug reports relating to it: Bug 162250 ? Feature Request: Better image scaling algorithms. http://bugzilla.gnome.org/show_bug.cgi?id=162250 Bug 343576 ? Lanczos resize not "the best" http://bugzilla.gnome.org/show_bug.cgi?id=343576 Bug 167956 ? scaling image causes an offset, particularly with Lanczos http://bugzilla.gnome.org/show_bug.cgi?id=167956 Bug 355178 ? transformation tools with Lanczos interpolation brighten the result http://bugzilla.gnome.org/show_bug.cgi?id=355178 The Lanczos algorithm does not use a 3x3 matrix. The code for Lanczos lives in two places: app/paint-funcs/scale-funcs.c -- for the "scale image" and "scale layer" commands app/core/gimpdrawable-transform.c -- for the transform tools As Sven pointed out, this code has been changing pretty rapidly in an effort to make it robust enough for inclusion in the upcoming 2.4 release, so it would be best to look at cvs HEAD if you want to avoid seeing things that are already obsolete. -- Bill ______________ ______________ ______________ ______________ Sent via the CNPRC Email system at primate.ucdavis.edu _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
