It looks like you are applying the transform in the wrong direction... > To compute a transformed coordinate (x', y') I simply multiply > (x, y, 1) by the transformation matrix that GIMP shows In that case, I think that the transformation converts the destination coordinate to the corresponding source coordinate. -- David Hodson -- this night wounds time _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
