Method Details

addConsumer

public void addConsumer(ImageConsumer pConsumer)

Specified by:

addConsumer in interface ImageProducer

removeConsumer

public void removeConsumer(ImageConsumer pConsumer)

Specified by:

removeConsumer in interface ImageProducer

requestTopDownLeftRightResend

public void requestTopDownLeftRightResend(ImageConsumer pConsumer)

This implementation silently ignores this instruction. If pixel data is not in TDLR order by default, subclasses must override this method.

Specified by:

requestTopDownLeftRightResend in interface ImageProducer

Parameters:

pConsumer - the consumer that requested the resend
