Header: afxrendertarget.h
The destructor. Called when a D2D radial gradient brush object is being destroyed.
virtual ~CD2DRadialGradientBrush();
Attaches existing resource interface to the object
void Attach(ID2D1RadialGradientBrush* pResource);pResource
Existing resource interface. Cannot be NULL
Constructs a CD2DLinearGradientBrush object.

pParentTarget
A pointer to the render target.
gradientStops
A pointer to an array of D2D1_GRADIENT_STOP structures.
gradientStopsCount
A value greater than or equal to 1 that specifies the number of gradient stops in the gradientStops array.
RadialGradientBrushProperties
The center, gradient origin offset, and x-radius and y-radius of the brush's gradient.
colorInterpolationGamma
