Examples of AImage

org.zkoss.image.AImage
Represents an image. Unlike java.awt.Image and javax.swing.ImageIcon, this class holds the raw image data, i.e., the original format, as opaque.
In other words, it is used to retrieve and store the opaque data as polymorphic thru the {@link org.zkoss.util.media.Media} interface.
To encode AWT image to an instance of {@link Image}, use {@link Images#encode}. @author tomyeh @see Images#encode
