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
