OCR Code adding Threading base Queuing per Yesterdays Logic
So this is amazing and was very much needed. I adopted our Threading Based Queuing code to integrate with Tesseract OCR to chuck out a HUGE WORKLOAD of processing. With the updated code a User can simply select multiple High Detailed images to render and then walk away, The Images are then all translated at …

In the example below I created 10 threads, Everytime Mod 3 = 0 is true, that thread …
