    Last Windows versions to have pixel art icons were Windows 2000/Me. Only leftovers remained in XP and later. You might like BeOS icons. They all have a distinct corner perspective though.

    Gamma correction is mostly irrelevant and superceded by color management, which can account for more differences in the transfer curve and primary colors. Usually a foreign monitor will produce...

    It appears to be straightforward maximum deviation of any of the color components. I tried it on a set of primary color gradients, and a tolerance of 64 to white replaced one quarter of the image,...

    What I meant to say is that one can't rely on a JFIF marker or text string to detect the start of a JPEG file, as it is optional and could occur later in the data or not at all. The IV optimization...

    The basic color reduction method is indeed bad, it adds 240 for white. "Best color quality" is very slow, but selected 255,255,254 and 3,2,3, which are very close to white/black. The new "best"...
