Shane Bryzak commented on JBSEAM-865:
-------------------------------------

I suppose I'd better add some more info :)

To configure a custom captcha image generator, configure the captchaImage component in components.xml like this:

<component name="org.jboss.seam.captcha.captchaImage" service="#{customCaptcha.service}"/>

Then create a method somewhere in your project that returns your customised ImageCaptchaService :

@Name("customCaptcha")
public class CustomCaptcha
{
   public ImageCaptchaService getService()
   {
      BasicGimpyEngine customCaptcha = new BasicGimpyEngine();
      GimpyFactory factory = new GimpyFactory(
            new RandomWordGenerator("ABCDEFGHIJKLMNOPQRSTUVWXYZ23456789"), 
            new ComposedWordToImage(new RandomFontGenerator(new Integer(15), 
                  new Integer(15)), new UniColorBackgroundGenerator(new Integer(150), 
                        new Integer(30)), new RandomTextPaster(new Integer(4), 
                              new Integer(7), Color.BLACK)));
      GimpyFactory[] factories = {factory};
      customCaptcha.setFactories(factories);
      
      return new DefaultManageableImageCaptchaService(
                   new FastHashMapCaptchaStore(),
                   customCaptcha,
                   180,
                   120000,
                   75000);      
   }
}


You can see this in action in the seamspace example.
