And does it use cubic , linear, or sinc, or another algorithm for the scale?
Is it possible to scale down with this same accuracy?
So far i am pleased with the 2x enlarge results. Nicely done. If i could get these results with scale down i would be happy, happy. :)
It doesn't use interpolation/color-blending methods. Actually it will not change the colors in the palette. For example, if you have an image which uses only 16 colors, the upscaled image will also use 16 colors only. I might add a few algorithms that use color-blending in the future.
