Class PivotingImageShaper

java.lang.Object
  edu.uci.ics.jung.visualization.PivotingImageShaper

public class PivotingImageShaper
extends Object

Provides factory methods that, given a BufferedImage, an Image, or the fileName of an image, will return a java.awt.Shape that is the contiguous traced outline of the opaque part of the image. This could be used to define an image for use in a Vertex, where the shape used for picking and edge-arrow placement follows the opaque part of an image that has a transparent background. The methods try to detect lines in order to minimize points in the path
