All Implemented Interfaces:
RichComponent
public class ReflectedImageLabel
extends JLabel

A RichComponent which takes the supplied image, adds on 50% to the height of the image and draws a graduated alpha-blended reflection below the top aligned original image. The text (set by setRichText()) is drawn dynamically over the reflection, below the original image.

Authors:
nigel

private AlphaComposite alphaComposite

The desired alpha composite
private BufferedImage bufferedImage

The image with reflection
private static Font reference

A font used for reference purposes when evaluating the size of the rendered component
private String text

Creates a new instance, setting the width and the height that may be used by the RichContainer
ReflectedImageLabel(String imageURL, String text, int width, int height)

Creates a new instance, using the image specified in the URL string, the prefered dimensions and sets the Rich text as well
