long ago I came to
this page where was explained the flaws of average scaling methods. So when I wanted high quality resizes Id choose float point based resizing in Photoshop, although narrowing the options to bilinear. Now that there are wonderful resizers in avisynth and some plugins work in float point (smoothadjust,dfttest), wouldn't it be possible to implement this?
PD: didn't want to dig grave the splineresize thread.
