Preview The result of your settings will appear in the Preview without affecting the image until you click on OK.
Circle Depth in Percent Slider and input box allow you to set the "circularity" of the transformation, from rectangle (0%) to
circle (100%).
Offset Angle This option controlles the angle the drawing will start from (0 - 359), and so turns it around the circle center.
Map Backwards When this option is checked, the drawing will start from the right instead of the left.
Map from Top If unchecked, the mapping will put the bottom row in the middle and the top row on the outside. If checked, it
will be the opposite.
To Polar If unchecked, the image will be circularly mapped into a rectangle (odd effect). If checked, the image will be mapped
into a circle.
