of them except Bilinear and Nearest Neighbor are reasonably good,
Lanczos and Spline family are even better, the Lanczos family is
The larger kernel sizes (larger numbers) preserve small details better,
especially after several interpolation steps. Jim Watters extended the
original Dersch test: http://photocreations.ca/interpolator/
However, the large kernel have disadvantages too, especially for
graphical structures: http://wiki.panotools.org/Interpolation
It is worth noting that all PTGui internal interpolators are
anti-aliased now. There isn't a need to choose a different interpolator
for downsizing anymore.
