public abstract void onImageReleased (ImageWriter writer)
Callback that is called when an input Image is released back to
ImageWriter after the data consumption.
The client can use this callback to be notified that an input Image
has been consumed and released by the downstream consumer. More
specifically, this callback will be fired for below cases:
The application dequeues an input Image via the
dequeueInputImage() method,
uses it, and then queues it back to this ImageWriter via the
queueInputImage() method. After
the downstream consumer uses and releases this image to this
ImageWriter, this callback will be fired. This image will be
available to be dequeued after this callback.
The application obtains an Image from some other component (e.g.
an ImageReader), uses it, and then queues it to this
ImageWriter via queueInputImage().
After the downstream consumer uses and releases this image to this
ImageWriter, this callback will be fired.
| Parameters |

writer |
ImageWriter: the ImageWriter the callback is associated with. |
