Hi,

Does anyone has experience to use one thread to do Scanning acquire process and another thread for post-processing on the scanned image data? The reason why we need to do this is that we do not want our kodak scanner to slow down (or even pause) for awaiting the completion of image processing after page acquired, I know that the page acquired method is asynchronous, but it seems that the scanner sometimes slow down after a large batch of
pages scanned (the scan batch is not completed at that time).

I found that even I use one thread for image processing, if the workload of this thread is high, it will still affect the thread for scanning.

Does anyone provide me a solution for this?

Thanks for your kind attention,
Raymond

Raymond,
You can lower the priority of the thread that does image processing by assigning a value to its Priority property. You can also make it consume less time by frequently calling its Sleep method to make it yield and pass control to other threads.
