void	addConsumer(ImageConsumer ic) Registers an ImageConsumer with the ImageProducer for access to the image data during a later reconstruction of the Image.
protected void	computeRow(int y, int[] row) Overriden method from SyntheticImage

protected boolean	isStatic()
void	nextFrame()
void	nextFrame(int param)
void	removeConsumer(ImageConsumer ic) Removes the specified ImageConsumer object from the list of consumers currently registered to receive image data.
void	requestTopDownLeftRightResend(ImageConsumer ic) Requests, on behalf of the ImageConsumer, that the ImageProducer attempt to resend the image data one more time in TOPDOWNLEFTRIGHT order so that higher quality conversion algorithms which depend on receiving pixels in order can be used to produce a better output version of the image.

void	setValues(int type, float h, float s, float b)
void	startProduction(ImageConsumer ic) Registers the specified ImageConsumer object as a consumer and starts an immediate reconstruction of the image data which will then be delivered to this consumer and any other consumer which might have already been registered with the producer.

isStatic

protected boolean isStatic()

Overrides:

isStatic in class SyntheticImage

nextFrame

public void nextFrame()

addConsumer

public void addConsumer(ImageConsumer ic)

Description copied from interface: ImageProducer

Registers an ImageConsumer with the ImageProducer for access to the image data during a later reconstruction of the Image. The ImageProducer may, at its discretion, start delivering the image data to the consumer using the ImageConsumer interface immediately, or when the next available image reconstruction is triggered by a call to the startProduction method.

Specified by:

addConsumer in interface ImageProducer

Overrides:

addConsumer in class SyntheticImage

getRGBForLocation

private int getRGBForLocation(int x,
                              int y)

getHSBForLocation

public void getHSBForLocation(int x,
                              int y,
                              float[] hsbArray)

computeRow

protected void computeRow(int y,
                          int[] row)

Overriden method from SyntheticImage

Overrides:

computeRow in class SyntheticImage

isConsumer

public boolean isConsumer(ImageConsumer ic)

Description copied from interface: ImageProducer

Determines if a specified ImageConsumer object is currently registered with this ImageProducer as one of its consumers.

Specified by:

isConsumer in interface ImageProducer

Parameters:

ic - the specified ImageConsumer

Returns:

true if the specified ImageConsumer is registered with this ImageProducer; false otherwise.

removeConsumer

public void removeConsumer(ImageConsumer ic)

Description copied from interface: ImageProducer

Removes the specified ImageConsumer object from the list of consumers currently registered to receive image data. It is not considered an error to remove a consumer that is not currently registered. The ImageProducer should stop sending data to this consumer as soon as is feasible.

Specified by:

removeConsumer in interface ImageProducer

Parameters:

ic - the specified ImageConsumer

startProduction

public void startProduction(ImageConsumer ic)

Description copied from interface: ImageProducer

Registers the specified ImageConsumer object as a consumer and starts an immediate reconstruction of the image data which will then be delivered to this consumer and any other consumer which might have already been registered with the producer. This method differs from the addConsumer method in that a reproduction of the image data should be triggered as soon as possible.

Specified by:

startProduction in interface ImageProducer

Parameters:

ic - the specified ImageConsumer

See Also:

ImageProducer.addConsumer(java.awt.image.ImageConsumer)

nextFrame

public void nextFrame(int param)

requestTopDownLeftRightResend

public void requestTopDownLeftRightResend(ImageConsumer ic)

Description copied from interface: ImageProducer

Requests, on behalf of the ImageConsumer, that the ImageProducer attempt to resend the image data one more time in TOPDOWNLEFTRIGHT order so that higher quality conversion algorithms which depend on receiving pixels in order can be used to produce a better output version of the image. The ImageProducer is free to ignore this call if it cannot resend the data in that order. If the data can be resent, the ImageProducer should respond by executing the following minimum set of ImageConsumer method calls:

	ic.setHints(TOPDOWNLEFTRIGHT | < otherhints >);
	ic.setPixels(...);	// As many times as needed
	ic.imageComplete();
 

Specified by:

requestTopDownLeftRightResend in interface ImageProducer

Parameters:

ic - the specified ImageConsumer

ImageConsumer.setHints(int)
