ANA.TriColor
Convert an Image-Register (IR) to Black and White using an specified threshold
Intention
This command will convert the Content of an IR directly into an B/W Image using only 2 Colours: Black and White.
The difference between Black and White is made along a user specified threshold that can vary from 1 - all White - to 768 (all Black).
Using a value of 0 will internally use the optimum value of 383.
1. Capture Screenshot of open Browser and convert it to Three Colors
Here i have used a Color-Threshold of "0" that will evaluate to the default value of &H808080
You can do this with your own preferred window - just change the STW.

Here you can see the picture before and after the operation, using the Threshhold of &H808080 and a threshold of &HF0F0F0 the 4th picture has a Threshold of &HF010F0 and the last picture has a Threshold of &H1010F0.
2. Due to the used technology, there is no difference whether you use &H1010F0 or &HF01010
The Values are not sorted to RGB but play a role all together.

Remarks
This command is not optimized, it may take up to several seconds for large pictures.
For a Window with size 1140x1410 i needed 40572261 Ticks (Speedtable using DMP.1), this is 2.5 Seconds on my computer, as my system can process 16000000 Ticks in one second.
