### 10.8. Polar Coords

#### Overview

This filter is found in Image>Filters/Distorts/Polar Coords

It gives a circular or a rectangular representation of your image with all the possible intermediates between both.

#### Options

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 controles 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.
