Polar

Converts images from rectangular coordinates to polar coordinates, and vice versa.

Tip: This filter works well with layers containing horizontal or vertical lines, such as the Stripes or Checkerboard generators. A similar effect can be created with any image by adding the Line Screen or other related filters.
