public class: RenderableImageProducer [javadoc | source]
java.lang.Object
   java.awt.image.renderable.RenderableImageProducer

All Implemented Interfaces:
    Runnable, ImageProducer

An adapter class that implements ImageProducer to allow the asynchronous production of a RenderableImage. The size of the ImageConsumer is determined by the scale factor of the usr2dev transform in the RenderContext. If the RenderContext is null, the default rendering of the RenderableImage is used. This class implements an asynchronous production that produces the image in one thread at one resolution. This class may be subclassed to implement versions that will render the image using several threads. These threads could render either the same image at progressively better quality, or different sections of the image at a single resolution.
Field Summary
 RenderableImage rdblImage    The RenderableImage source for the producer. 
 RenderContext rc    The RenderContext to use for producing the image. 
 Vector ics    A Vector of image consumers. 
Constructor:
 public RenderableImageProducer(RenderableImage rdblImage,
    RenderContext rc) 
    Constructs a new RenderableImageProducer from a RenderableImage and a RenderContext.
    Parameters:
    rdblImage - the RenderableImage to be rendered.
    rc - the RenderContext to use for producing the pixels.

Method from java.awt.image.renderable.RenderableImageProducer Detail:
 public synchronized  void addConsumer(ImageConsumer ic) 
    Adds an ImageConsumer to the list of consumers interested in data for this image.
 public synchronized boolean isConsumer(ImageConsumer ic) 
    Determine if an ImageConsumer is on the list of consumers currently interested in data for this image.
 public synchronized  void removeConsumer(ImageConsumer ic) 
    Remove an ImageConsumer from the list of consumers interested in data for this image.
 public  void requestTopDownLeftRightResend(ImageConsumer ic) 
    Requests that a given ImageConsumer have the image data delivered one more time in top-down, left-right order.
 public  void run() 
    The runnable method for this class. This will produce an image using the current RenderableImage and RenderContext and send it to all the ImageConsumer currently registered with this class.
 public synchronized  void setRenderContext(RenderContext rc) 
    Sets a new RenderContext to use for the next startProduction() call.
 public synchronized  void startProduction(ImageConsumer ic) 
    Adds an ImageConsumer to the list of consumers interested in data for this image, and immediately starts delivery of the image data through the ImageConsumer interface.
