ANA.BW
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 BW
You can do this with your own preferred window - just change the STW.

' If you use the value of "0", it will internally be used 383

ENR.
Here you can see the picture before and after the operation, using the Threshhold of 383 and a threshold of 128.
2. Use BW with no Parameters
In this case the default values are taken, means "0" as the Source and Target IR, and &H17f (383 dec.) as threshold.

Remarks
This command is not optimized, it may take up to several seconds for large pictures.
For a Window with size 1140x1410 i needed 36867812 Ticks (Speedtable using DMP.1), this is 2.3 Seconds on my computer, as my system can process 16000000 Ticks in one second.
