Hi,
I have another question(sorry...) regarding when an ImageConsumer removes
itself from an ImageProducer. I have the following code frag:
public void frameCallback(String frame, int width, int height) {
System.out.println("Java: frameCallback received " + frame + " " +
width + " " + height);
if(theConsumer != null)
System.out.println("Consumer has not been removed");
byte frameB[];
frameB = new byte[width*height];
frame.getBytes(0, frame.length(), frameB, 0);
theConsumer.setPixels(0, 0, width, height,
parentFrame.getColorModel(), frameB, 0, width);
theConsumer.imageComplete(theConsumer.SINGLEFRAMEDONE);
}
If I put a test print in the removeConsumer method from my ImageProducer I
see that it is called to remove "theConsumer" after frameCallBack is called
for the first time. Any ideas?
I init my stream using a frame that I have created and its
createImage(ImageProducer) method. I then set the ImageProducer in motion
via a native method call and the native libs callback the above to
"hopefully" display frames.
Thanks.
