Remarks

A CogCircularAnnulusSection or CogEllipticalAnnulusSection that specifies the region to be unwrapped.

The tool unwraps the specified region of the input image so that the x-axis of the transformed image always corresponds to the angular direction of the region and the y-axis of the transformed image always corresponds to the radial direction of the region.

The values of the RadialScale and AngleSpan properties determine the relationship between the x-axis and y-axis in the output image and increasing and decreasing radius and angle in the input region. as shown in this table.
