Assembly:  Microsoft.Graphics.Canvas (in Microsoft.Graphics.Canvas.dll) Version: 0.0.0.0

	ICanvasBrush opacityBrush,
	CanvasGeometry clipGeometry,
	Matrix3x2 geometryTransform
)

Parameters

Return Value

Type: CanvasActiveLayer
Remarks

The layer affects all drawing until the returned CanvasActiveLayer object is closed. In C# this is typically done with a 'using' statement, or in C++/CX the 'delete' keyword.

Antialising mode of the clip geometry is determined by the value of the Antialiasing property when CreateLayer is called.

For more information about layers, see CanvasActiveLayer.
