Kathy, not really sure how to resample in PSP.  I have heard about resampling as opposed to resizing but I'm not sure how it works.

In PSPXI, I have a RESAMPLE tick in the Resize option popup.  I can resample by:
Bicubic
Bilinear
Pixel Resize
smart size
Weighted average.

I don't understand what the difference is for these.  Would one of these be similar to what you are describing?
