public class Map_LogPolar_Demo
extends Object
implements PlugInFilter, MouseListener, JavaDocHelp

ImageJ plugin demonstrating the use of 2D log-polar mapping. Two mapping types are available (Version1, Version2). See Sec. 21.1.6 of [1] for details and examples. The plugin works interactively. Once started, the current mouse position specifies the transformation's center point. A new image with radius/angle coordinates is opened and continuously updated, until the plugin is terminated. The circular source grid is displayed as a graphic overlay.
