CD2DLayer(
CRenderTarget* pParentTarget,
BOOL bAutoDestroy = TRUE);
Parameters
pParentTarget
A pointer to the render target.
bAutoDestroy
Indicates that the object will be destroyed by owner (pParentTarget).
CD2DLayer::Create

ID2D1Layer* Get();
Return Value
Pointer to an ID2D1Layer interface or NULL if object is not initialized yet.
CD2DLayer::GetSize
Returns the size of the render target in device-independent pixels
CD2DSizeF GetSize() const;
Return Value
The current size of the render target in device-independent pixels
CD2DLayer::IsValid
Checks resource validity
virtual BOOL IsValid() const;
Return Value
TRUE if resource is valid; otherwise FALSE.

ID2D1Layer* m_pLayer;
CD2DLayer::operator ID2D1Layer*
Returns ID2D1Layer interface
operator ID2D1Layer* ();
Return Value
Pointer to an ID2D1Layer interface or NULL if object is not initialized yet.
