Cubic seems to be giving much better results now. Thanks again Øyvind! I no longer feel it necessary to always switch to NoHalo. Thankyou thankyou thankyou! Much respect, -C On Mon, May 9, 2016 at 4:15 PM, Akkana Peck wrote: > > > On 07/05/16 15:38, Øyvind Kolås wrote: > > >> I've pushed code

Awesome! Thanks. :) It will be great to get a decent result from cubic again. -C On Sat, May 7, 2016 at 2:38 PM, Øyvind Kolås wrote: > On Wed, Apr 27, 2016 at 10:03 AM, C R wrote: > > I assume the reasoning behind using cubic as the default for all the > scale > > and transform tools is to cut

I suspect that it would make very little difference when downsampling, but maybe sigmoidization, as used in LoHalo, is not worth the computational cost. Very easy to modify the code: Remove the extended_sigmoidal and inverse_sigmoidal function definitions, and then replace these strings (which tr

Are there plans to fix the cubic interpolation so it doesn't toss away quite so much resolution? It seems to me it didn't do that quite so much before. -C On Fri, Apr 29, 2016 at 12:34 AM, Liam R. E. Quin wrote: > On Fri, 2016-04-29 at 00:59 +0200, Nicolas Robidoux wrote: > > Liam: > > > > Do

[Gimp-developer] Cubic Interpolation vs No Halo

2016-04-27 Thread C R
I assume the reasoning behind using cubic as the default for all the scale and transform tools is to cut back on the complaints of how slow GIMP is at the moment, but the quality loss in the current cubic interpolation algorithm is quite bad. Can we shift the default to No Halo or Lo Halo? Also, i
