java.lang.Object | +--java.awt.image.renderable.RenderableImageProducer
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.
Constructor Summary | |
RenderableImageProducer(RenderableImage rdblImage,
RenderContext rc)
Constructs a new RenderableImageProducer from a RenderableImage and a RenderContext. |
Method Summary | |
void |
addConsumer(ImageConsumer ic)
Adds an ImageConsumer to the list of consumers interested in data for this image. |
boolean |
isConsumer(ImageConsumer ic)
Determine if an ImageConsumer is on the list of consumers currently interested in data for this image. |
void |
removeConsumer(ImageConsumer ic)
Remove an ImageConsumer from the list of consumers interested in data for this image. |
void |
requestTopDownLeftRightResend(ImageConsumer ic)
Requests that a given ImageConsumer have the image data delivered one more time in top-down, left-right order. |
void |
run()
The runnable method for this class. |
void |
setRenderContext(RenderContext rc)
Sets a new RenderContext to use for the next startProduction() call. |
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. |
