Re: [Gimp-developer] comparison of enlargements produced with two GIMP methods, three GEGL methods, and three candidate GEGL methods
In light of some feedback received, me and my students will be making major changes to three of the gegl methods, so you may want to wait until the comparisons are updated.

Re: [Gimp-developer] comparison of enlargements produced with two GIMP methods, three GEGL methods, and three candidate GEGL methods
To illustrate the effect of the samplers on images from the opposite end of the spectrum (text as opposed to natural), I have put together a similar comparison with a text image created with GIMP. It shows 9.73x 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 tar archive http://web.cs.laurentian.ca/nrobidoux/misc/textenlargementtests.tgz To know which method was used to produce each image (and get runtimes for the GEGL methods), read the KEY text file.

One thing I noticed when looking at these images is that the GEGL ops all create a black border at the bottom-right edges. Is that something you are aware of and expect to get fixed ?
