Class MagickProducer
- ImageProducer
public class MagickProducer
implements ImageProducer
This class implements the ImageProducer class.
It reads the pixels off a MagickImage and sends
the pixels to the specified ImageConsumer.
void | addConsumer(ImageConsumer consumer)- This method is used to register an ImageConsumer with the
ImageProducer for access to the image data during a later
reconstruction of the Image.
|
boolean | isConsumer(ImageConsumer consumer)- This method determines if a given ImageConsumer object is
currently registered with this ImageProducer as one of its
consumers.
|
void | removeConsumer(ImageConsumer consumer)- This method removes the given ImageConsumer object from the
list of consumers currently registered to receive image data.
|
void | requestTopDownLeftRightResend(ImageConsumer consumer)- This method is used by an ImageConsumer to request 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(ImageConsumer consumer)- This method both registers the given 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 may have already been registered
with the producer.

MagickProducer
public MagickProducer(MagickImage image)
Constructor.
image - the MagickImage to produce an Image from
addConsumer
public void addConsumer(ImageConsumer consumer)
This method is used to register an ImageConsumer with the
ImageProducer for access to the image data during a later
reconstruction of the Image.
consumer - to register with the producer
isConsumer
public boolean isConsumer(ImageConsumer consumer)
This method determines if a given ImageConsumer object is
currently registered with this ImageProducer as one of its
consumers.
consumer - to consumer to register with the producer
removeConsumer
public void removeConsumer(ImageConsumer consumer)
This method removes the given 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.
consumer - the consumer to check for registration
requestTopDownLeftRightResend
public void requestTopDownLeftRightResend(ImageConsumer consumer)
This method is used by an ImageConsumer to request 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.
consumer - the consumer to register before producing the image
startProduction
public void startProduction(ImageConsumer consumer)
This method both registers the given 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 may have already been registered
with the producer.
consumer - to be registered before producing the image
