All Implemented Interfaces:

public class SizedImageTag
extends javax.servlet.jsp.tagext.SimpleTagSupport

Implements the wm:sizedImage tag. Resizes image objects. If the aspect ratio (height:width) of the resized image is different than the source image, the image will be cropped from the top and bottom or left and right to avoid getting black bars. Returns the resized image object.

 < wm:sizedImage var="bulletSmall" image="${bullet}" width="20" height="20" />
