public class JCIconCreator

extends Object

JCIconCreator creates image icons from String arrays. The format is similar to XPixMap (XPM) format files. For example:

     JCIconCreator im = new JCIconCreator(3, 2);
     im.setColor('G', Color.green);
     im.setColor('x', Color.orange);
     String[] pixels = { " .G", "G x" };
     im.setPixels(pixels);
     ImageIcon icon = im.getIcon();
