Image Streamer Cross-Process

• Initializing the ImageStreamer Module as a Producer
• Initializing the ImageStreamer Module as a Consumer

In addition to using the ImageStreamer module in a single process, you can also use it across multiple processes.

To utilize the ImageStreamer Cross-Process module, specify the ImageStreamer as either PRODUCER or CONSUMER
at initialization before streaming the image. For details on how to create and convert an image, please refer to
Image Creation and Conversion. All other details are left out of this tutorial for simplicity.

Initializing the ImageStreamer Module as a Producer

// Process 1:
dwImageStreamer_initializeCrossProcess(..., PRODUCER);
while(true)
{
    // CODE: Get an image to stream
    dwImageStreamer_producerSend(...);
    dwImageStreamer_producerReturn(TIMEOUT);
}
dwImageStreamer_release(...);

Initializing the ImageStreamer Module as a Consumer

// Process 2:
dwImageStreamer_initializeCrossProcess(..., CONSUMER);
while(true)
{
    dwImageStreamer_consumerReceive(TIMEOUT);
    // CODE: Use the streamed image
    dwImageStreamer_consumerReturn(...);
}
dwImageStreamer_release(...);
