Help for POLARECT2

PURPOSE:
To convert images to polar coordinates and back.

METHOD:
In DIRECT mode:
output lines are radial profiles of fixed scale (1:1 pixel scale).
Lines always extend from 0 to 360 degrees in azimuth clockwise from the right.
In INVERSE mode:
Lines and samples are cartesian coordinates.

EXECUTION:
(Initial image is 400 by 400)
polarect2 inp=a out=b nl=100 ns=100 center=(200,200) 'direct
polarect2 inp=b out=c nl=400 ns=400 center=(200,200) 'inverse
