public interface ImageProducer
Modifier and Type | Method | Description |
---|---|---|
void |
addConsumer |
Registers an ImageConsumer with the ImageProducer for access to the image data during a later reconstruction of the Image . |
boolean |
isConsumer |
Determines if a specified ImageConsumer object is currently registered with this ImageProducer as one of its consumers. |
void |
removeConsumer |
Removes the specified ImageConsumer object from the list of consumers currently registered to receive image data. |
void |
requestTopDownLeftRightResend |
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 |
startProduction |
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. |
void addConsumer(ImageConsumer ic)
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.ic
- the specified ImageConsumer
boolean isConsumer(ImageConsumer ic)
ImageConsumer
object is currently registered with this ImageProducer
as one of its consumers.ic
- the specified ImageConsumer
true
if the specified ImageConsumer
is registered with this ImageProducer
; false
otherwise.void removeConsumer(ImageConsumer ic)
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.ic
- the specified ImageConsumer
void startProduction(ImageConsumer ic)
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.ic
- the specified ImageConsumer
void requestTopDownLeftRightResend(ImageConsumer ic)
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();
ic
- the specified ImageConsumer
