If you use just 133.00%, the result will be the wrong dimensions and so, uncomparable. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hi, in what way do you mean the results are analogous to lancsoz? Could you perhaps compare results of your plugin with the comparitive results on the kingfisher head shot? http://svenfoo.org/scaletest/133-9.html http://svenfoo.org/scaletest/133Z8g.png http://svenfoo.org/scaletest/133C8g.png and/or the pixel graphic: http://svenfoo.org/scaletest/133-8.html http://svenfoo.org/scaletest/133Z8g.png http://svenfoo.org/scaletest/133C8g.png these two images scaled to 133% seemed to be the best cases in that test group for differentiating cubic and lancsoz. It would be interesting to see your plugin results next to those tests. The originals are provided on those html pages. regards. -- ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
