Class SVGImageFilter

java.lang.Object
  java.awt.image.ImageFilter
      cwi.SVGGraphics.SVGImageFilter

All Implemented Interfaces:

java.lang.Cloneable, java.awt.image.ImageConsumer

public class SVGImageFilter

extends java.awt.image.ImageFilter

A simple image filter, which adds a "url" property to the image object. Otherwise the image is not changed.

A possible and simple use of the filter is as follows:

     import java.awt.image.*;
     ...
     ImageFilter addProperty = new SVGImageFilter("The.URL.of.the.image");
     FilteredImageSource imageSource = new FilteredImageSource(oldImg.getSource(),addProperty); 
     Image newImg = Toolkit.getDefaultToolkit().createImage(imageSource);
 

The class also includes two static methods which simply include these lines, and can be used as a simple tool.
