Class GVectorImage

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              vectorimage.GVectorImage

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class GVectorImage
extends javax.swing.JComponent

A GVectorImage is the graphical representation of the vector image defined by its underlying image source. Simply add it to a GUI to see it, or use getImage to obtain an image.
