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 controls 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

To polar
