Hi Ullrich,
Now, off the pixel/color topic. rom the Quicktime format disccusion: is it possible to supersample (rather than subsample) an image? That is, to take two or more consequtive pixels in a row and pretend is just one pixel?
Regarding terminology: 'supersampling' is commonly understood as creating more sampling points than were originally available,
Right, that's my understading of supersampling.
whereas 'subsampling' reduces the number of sampling points (opposite to your use of the term).
GIL's subsample_view skips pixels (takes less sampling points) and I was thinking in doing sort of the opposite: take 2 or more pixels from the source image as if they were multiple samples from the same "point", that is, mapped into just one pixel in the target. That's why I referred to it as supersampling. Best Fernando Cacciola SciSoft http://fcacciola.50webs.com/
