By default, the SweepAngle property is empty, which indicates 0 degree. The SweepAngle property is 0 degree, if empty, missing or invalid.

For instance:

• "-45", 45 degree anti-clockwise
• "90", 90 degree clockwise
• "value" specifies that the angle is equal with the clip's Value property
• "value / 100 * 360" results the percent Value from 360 degree

This property supports the following keywords:

• value keyword specifies the clip's value pointed by the clip's Value property
• width or lwidth keywords, indicates the width in pixels of the layer
• height or lheight keywords, indicates the height in pixels of the layer

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 elliptical clip region over the layer you can use any of the following properties:

• CenterX, Specifies the x-position / expression of the center of the clip, relative to the layer.
• CenterY, Specifies the y-position / expression of the center of the clip, relative to the layer.
• RadiusX, Specifies the x-radius value / expression of the clip, relative to the layer.
• RadiusY, Specifies the y-radius value / expression of the clip, relative to the layer.
• StartAngle, Specifies the starting angle in degrees relative to the y-axis.
• SweepAngle, Specifies the sweep angle in degrees relative to the starting angle.

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

• OffsetX, Specifies the x-offset expression / value of the clip, relative to the layer.
• OffsetY, Specifies the y-offset expression / value of the clip, relative to the layer.

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.
