Show large shows image (1b, 3b, or 4b per pixel).
Also if you cklick right mouse button on any pixel it shows x,y RGB and HSV of that pixel.
Wery helpful, everybody must have this!

. I only had to add a single mask for digit '1' (there was also a '1' with a width of 4 instead of 5). Tomorow i will test a lot more stacks, cause today most of my work has been with this live result scraper viewer (see Screenshot). This way i can easily check if all stacks are recognized correctly during live play. Instead of gathering screenshot after screenshot and check afterwards.
