Remarks

CGLayers can be hardware accelerated and developers are encouraged to use this instead of CGBitmaps for off-screen rendering operations.

To create CGLayers, use the Create(CGContext, CGSize) method.

Once you create a CGLayer, you extract the CGContext instance by accessing the Context property.

Properties

Context	Returns the graphics context associated with this layer.
Handle	Handle (pointer) to the unmanaged object representation.
Size	The size of the CGLayer

Methods

Create(CGContext, CGSize)	Creates a new CGLayer object with the specified graphics context and size
Dispose()	Releases the resources used by the CGLayer object.
Dispose(Boolean)	Releases the resources used by the CGLayer object.
Finalize()	Finalizer for the CGLayer object
