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

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.

X, Y

These polar coordinates are active only if the “Choose middle” option is unchecked.

Choose middle

Checked by default: origin center is at the middle of the layer. If unchecked, you can modify X and Y parameters to position the origin center.
