I have created 6.11x enlargements with two GIMP methods, three GEGL methods, and three candidate GEGL methods for which patches are provided in https://bugzilla.gnome.org/show_bug.cgi?id=619314 The enlargements, named a.png to h.png, are found in the 15M tar archive http://web.cs.laurentian.ca/nrobidoux/misc/catenlargementtests.tgz To know which method was used to produce each image, read the KEY text file. One of the three candidate methods is very fast. The total runtime for the creation of the enlargement with upsmooth is only 15% more than with bilinear. Only one of the three candidate methods is slower than GEGL bicubic (upsharp, by 30%). Nicolas Robidoux PS Warning: the upsize, upsmooth and upsharp samplers already in GEGL are prototypes of the methods showcased in the above enlargement test. _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
