This command converts an image from Cartesian (rectangular) coordinates to polar coordinates or vice versa. Rectangular coordinates use the form (x, y) where ‘x’ and ‘y’ are the horizontal and vertical distances from the origin, respectively. Polar coordinates are in the form (r, E) where ‘r’ is the distance from the origin to the point and ‘E’ is the angle of the line the point makes with the positive x-axis. Polar coordinates use a grid made of concentric circles around the origin, along with lines that are rays radiating outward from the origin.
This command considers the positions of the image’s pixels as values in a polar coordinate system. Then it converts all the pixels in a line of the image into a circle around the center of the image.
This command does not support signed data images.
