Look, I already told you to use a normalized Lanczos 3 kernel. If you need convincing,
1. Download a free demo copy of my software at

2. Examine the results of Lanczos 3 subpixel shifts by using Geom>Rotate Arbitrary Angle and/or Shift.
Was this adequate, "yes" or "no"?
aruzinsky, I tried your software and it worked great for doing a sub-pixel shift. In my code, I need shift an image by sub-pixel increments of 1/2 pixel, 1/4 pixel, 1/8 pixel, etc. to the right and down. Could you help by pointing me to a reference on
how to create the correct kernels, and how to apply them? Thanks, Scott
