| Methods Summary |
|---|
| public void | addConsumer(java.awt.image.ImageConsumer ic)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.
|
| public boolean | isConsumer(java.awt.image.ImageConsumer ic)Determines if a specified ImageConsumer
object is currently registered with this
ImageProducer as one of its consumers.
|
| public void | removeConsumer(java.awt.image.ImageConsumer ic)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.
|
| public void | requestTopDownLeftRightResend(java.awt.image.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. 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();
|
| public void | startProduction(java.awt.image.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. This method differs
from the addConsumer method in that a reproduction of
the image data should be triggered as soon as possible.
