Talk:Resize

Changes Feb 2016

I removed any references to VirtualDub resizer quality, pending more testing:

“BilinearResize uses standard bilinear filtering and is almost identical to VirtualDub's "precise bilinear" resizing option. It's only "almost" because VirtualDub's filter seems to get the scaling factor slightly wrong, with the result that pixels at the top and right of the image get either clipped or duplicated. (This error is noticeable when expanding the frame size by a factor or two or more, but insignificant otherwise, so I wouldn't worry too much about it.)

(Does anyone know the origin of this statement? The premise is not correct, as with standard mappings you must have duplicated or mirrored pixels around the border when enlarging. Looking at the sources and comparing outputs, VirtualDub 1.6 and Avisynth 2.5 appear to generate the same mappings. I wonder if this discrepancy has already been resolved. ? Avery)” ^[1]

The information was almost certainly out of date. As always, suggestions & criticism welcome.
