This tool is used to perform a nonlinear resize (or "warp") of an image. By warping, you can resize an image such that the objects in the center of an image remain clear and undistorted, and distortion occurs near the edges of the image. This tool is useful for situations where you need to convert an image from one aspect ratio to another without cropping.
