Similarly, if you set the width field to "value*2", it means that the width of the clipping region is twice the clip's value or the Gauge.Value property, so when the value changes, the width of the clipping region changes accordingly. The interpretation of the clip's value depends on how you use it in the expressions for defining the clipping region. By default, the value field is null, which means that it is not linked to any expression and does not affect the clipping region.

The value field is mapped to the LayerClip.Value property, which means that the following statements are equivalent:

oClip.Options = {value: 50}
oClip.SetOptions({value: 50})
