public class ReflectionBehavior
extends org.apache.wicket.behavior.Behavior

Behavior for adding reflections to an image. Uses reflection.js (v1.6), licensed under a MIT license.

Add this behavior to your image to generate a reflection. You can change the height and opacity of the reflection using the provided setters.

Ultimately the markup you attach this behavior to must be an image, but it need not be a Wicket Image component, a markup container will suffice, provided the tag is an img-tag.

You can also use this class to generate add and remove reflection scriptlets for use in Ajax request targets or any other place you want. All you need to do is ensure the reflection.js is added to the head of the document. You can use the REFLECTION_JS resource reference for that.

The reflection.js library and more documentation can be found here http://cow.neondragon.net/stuff/reflection/
