Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.awt.Image`	`produceImage(int width, int height)`	Images are useful for doing double buffering.
`java.awt.Image`	`produceImage(java.awt.image.ImageProducer producer)`	`getGraphics()` on the returned image will fail; in other words the returned image is good for rendering and not so good for drawing onto.
`void`	`requestUpdate()`	This method triggers a call to `update(Graphics)` on a corresponding `AbstractCanvas`.

- Method Detail
  - produceImage
```
java.awt.Image produceImage(int width,
                            int height)
```
    Images are useful for doing double buffering. The returned image can be rendered and it can be drawn into by way of getGraphics().
  - produceImage
```
java.awt.Image produceImage(java.awt.image.ImageProducer producer)
```
    getGraphics() on the returned image will fail; in other words the returned image is good for rendering and not so good for drawing onto.
  - requestUpdate
```
void requestUpdate()
            throws java.lang.IllegalMonitorStateException
```
    This method triggers a call to update(Graphics) on a corresponding AbstractCanvas. This method blocks until the update() method finishes. By agreement, this method shall only be called by a corresponding AbstractCanvas, and only by the thread invoking AbstractCanvas.run().
    
    Throws:
    
    java.lang.IllegalMonitorStateException - if a second thread calls this method.
