That's obviouly wrong. The only difference between this file in my ancient patch and this verion is the function name, the comment, the #include, and some whitespace. After 11 years (that makes me feel old), I don't remember whether any of the code is based on code from the Gimp or if it was rewritten from scratch after working out the algorithm. The trickiest bit resembles the macro INT_MULT defined in app/paint_funcs.c.[1] The credit from that file is: * The GIMP -- an image manipulation program * Copyright (C) 1995 Spencer Kimball and Peter Mattis [1] ftp://ftp.gimp.org/pub/gimp/v1.1/old/v1.1.24/gimp-1.1.24.tar.bz2 -- To unsubscribe, send mail to [email protected].
