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.
