Hi, All,

Here is a question on interpolation and resampling.
....
My questions are:

- what can be inferred about the nature of the interpolation method
employed given only the above information?
- on the resample circle image, the circle profile displays some 'saw
tooth' patterns. Is that an artifact/limitation of interpolation
scheme? Or it is expected?
- if you think there are artifacts in the resampled images, what could
be a possible solution or a better way to resample?

The interpolated images contain only black
and white, no gray. Perhaps the problem is
that your output images are binary when they
should be graytone.
