On Region Change - ABBYY Documentation

When it is launched

The script runs before a region is modified in the image window.

If the AllowChangeRegion.Value property is set to true, the region is changed after the script executes.
If the AllowChangeRegion.Value property is set to false, the region is not changed.

By default, the value of the AllowChangeRegion parameter is true.
