Topic: Bicubic spline bug/NEDI
first thank you for developing this great image processing software for years.
I've found a bug which might be there since version 1.31(?). At least on 64bit systems (Win7, Debian) bicubic spline resize is damaging images. It introduces some weird lines to them. It should be fixed sometime.
Btw. haven't you been thinking about implementing NEDI? (google: new edge directed interpolation - alexey lukin). His demo scales up in quality comparable with the most expensive resizing software.
I know about Fractal Interpolation/Xin Li but I'm not sure if it is the same.
Enjoy the rest of your holiday!
