ImageProducer| Constructor and Description |
|---|
FilteredImageSource(ImageProducer orig,
ImageFilter imgf)
Constructs an ImageProducer object from an existing ImageProducer
and a filter object.
|
| Modifier and Type | Method and Description |
|---|---|
void |
addConsumer(ImageConsumer ic)
Adds the specified
ImageConsumer
to the list of consumers interested in data for the filtered image. |
boolean |
isConsumer(ImageConsumer ic)
Determines whether an ImageConsumer is on the list of consumers
currently interested in data for this image.
|
void |
removeConsumer(ImageConsumer ic)
Removes 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 |
startProduction(ImageConsumer ic)
Starts production of the filtered image.

Component.createImage(java.awt.image.ImageProducer)public void addConsumer(ImageConsumer ic)
ImageConsumer
to the list of consumers interested in data for the filtered image.
An instance of the original ImageFilter
is created
(using the filter's getFilterInstance method)
to manipulate the image data
for the specified ImageConsumer.
The newly created filter instance
is then passed to the addConsumer method
of the original ImageProducer.
This method is public as a side effect
of this class implementing
the ImageProducer interface.
It should not be called from user code,
and its behavior if called from user code is unspecified.
