com.sun.pdfview.RefImage
public class RefImage
A BufferedImage subclass that holds a strong reference to its graphics object. This means that the graphics will never go away as long as someone holds a reference to this image, and createGraphics() and getGraphics() can be called multiple times safely, and will always return the same graphics object.
