Rahul: > exact area box filtering with sides no less than the input image's > inter-pixel distance This was a bit terse: Exact area box filtering with a square box with diameter equal to the inter-pixel distance is exactly bilinear interpolation. So, it's only when the sides are larger than the scheme is not bilinear. nicolas _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
