I am posting this for a friend who is currently without acces to usenet. I will forward any posted reply, or e-mail replies. The person has their e-mail at the end. #################################################################### I am looking for an IDL procedure, or a FORTRAN or C program that can be linked to IDL, which would rotate images using a cubic interpolation algorithm. More generally, I would be looking for an emulation of POLY_2D that would include a cubic interpolation option. Our group has found (using a mainframe) that rotation with cubic interpolation significantly reduces the smearing that can occur when using the bilinear algorithm. There is, of course, a significant increase in computation time, but workstations are now powerful enough that this can be an interactive option.
