The Polar tool lets you transform the input image from Cartesian coordinates to Polar coordinates or vice versa. When using Polar to Cartesian, the effect stretches a round object so that it appears to straighten out. When using Cartesian to Polar, the effect bends an image around its center so that it appears round.
An option menu is used to choose if the transformation is from Cartesian to Polar or Polar to Cartesian.

The Polar to Rectangular tool has the following parameters:
| Use: | To: |
|---|---|
| Mode | To switch between Polar to Cartesian and Cartesian to Polar (default is Cartesian to Polar). |
| Offset | Rotate the result of the Cartesian to Polar conversion and offset the result of the Polar to Cartesian conversion. The value is expressed as an angle that represent a circular offset in Cartesian To Polar and an horizontal offset Polar to Cartesian mode. |
