INP
1 input image
OUT
1 Output image.
Image has NL lines and NS samples.
In DIRECT mode each line is a radial profile from the
center (left) to the edge of the image (right). Line 1 is zero degrees azimuth.
NL
Number of output lines.
You always get 360 degrees of azimuth for any value of NL.
NS
Number output samples.
The radial scale is fixed for a 1:1 aspect ratio. So if you set ns=100 you
only get the first 100 radial samples.
CENTER
Center (line,sample)
Specifies the center of the polar coordinate transformation in the cartesian
image.
MODE
Specifies the projection type:
Direct or Inverse
Direct means cartesian to polar
Inverse means polar to cartesian
RESAMP
Whether to interpolate or not.
Interp means to use bilinear interpolation.
Nointerp means to use nearest neighbor
