Bill: There are already two fast nonlinear resamplers implemented in GEGL: YAFR (gegl-sampler-yafr.c) and Nohalo-sharp (gegl-sampler-sharp.c). Both are a little slower than gegl-sampler-linear, but faster than gegl-sampler-bicubic. See the (informal) benchmarks at http://bugzilla.gnome.org/show_bug.cgi?id=566717 Code wise, you may want to have a look at the following: http://svn.gnome.org/viewvc/gegl/trunk/gegl/buffer/gegl-sampler-sharp.c?revision=2881&view=markup This is the lowest quality/fastest version of a scheme which, at higher quality levels, should compete advantageously will NEDI in the good looks department. Nohalo-sharp is (literally as we speak!) also being implemented in vips, and on the GPU (with DirectX). A not yet implemented variant of the scheme, Nohalo-Smooth, will look smoother (duh!). YAFR (Yet Another Fast Resampler) is likely to be made obsolete by the higher level nohalos. See: http://svn.gnome.org/viewvc/gegl/trunk/gegl/buffer/gegl-sampler-yafr.c?view=markup ------ I'd love manpower (GSoC?) to implement Nohalo-Smooth and/or either Nohalo at higher quality levels.
