property ClipPolygon.X(Index as Long) as String
Specifies the x-position expression / value of the point, relative to the layer.

TypeDescription
Index as Long A Long expression that specifies the index of the point, whose x-coordinate is accessed. The Index parameter is zero-based, so it can be 0, 1, 2, ...  Points - 1
String A String value that specifies the x-position expression / value of the point, relative to the layer.
By default, the X property is empty, which indicates the value of 0 ( left side of the layer ). The X property is 0, if the expression is empty, missing or invalid. The Points property indicates the number of points that defines the polygon.

For instance:

This property supports the following keywords:

Also, this property supports all constants, operators and functions defined here.

The following screen shot shows properties of the clipping objects relative to the layer:

To define an polygonal clip region over the layer you can use any of the following properties:

To move the clipping region you can use any of the following properties:

If none of these properties are calling no clipping is applied to layer.

The InverseClip property inverses the current clipping region, so anything that was included in the clipping region will be excluded, and reverse.
