CD2DGradientBrush::~CD2DGradientBrush

The destructor. Called when a D2D gradient brush object is being destroyed.

virtual ~CD2DGradientBrush();

CD2DGradientBrush::CD2DGradientBrush

Constructs a CD2DGradientBrush object.

CD2DGradientBrush(
    CRenderTarget* pParentTarget,
    const D2D1_GRADIENT_STOP* gradientStops,
    UINT gradientStopsCount,
    D2D1_GAMMA colorInterpolationGamma = D2D1_GAMMA_2_2,
    D2D1_EXTEND_MODE extendMode = D2D1_EXTEND_MODE_CLAMP,
    CD2DBrushProperties* pBrushProperties = NULL,
    BOOL bAutoDestroy = TRUE);

Parameters

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.

colorInterpolationGamma
The space in which color interpolation between the gradient stops is performed.

extendMode
The behavior of the gradient outside the [0,1] normalized range.

pBrushProperties
A pointer to the opacity and transformation of a brush.

bAutoDestroy
Indicates that the object will be destroyed by owner (pParentTarget).

CD2DGradientBrush::Destroy

Destroys a CD2DGradientBrush object.

virtual void Destroy();

CD2DGradientBrush::m_arGradientStops

Array of the D2D1_GRADIENT_STOP structures.

CArray<D2D1_GRADIENT_STOP, D2D1_GRADIENT_STOP> m_arGradientStops;

CD2DGradientBrush::m_colorInterpolationGamma

The space in which color interpolation between the gradient stops is performed.

D2D1_GAMMA m_colorInterpolationGamma;

CD2DGradientBrush::m_extendMode

The behavior of the gradient outside the [0,1] normalized range.

D2D1_EXTEND_MODE m_extendMode;

CD2DGradientBrush::m_pGradientStops

A pointer to an array of D2D1_GRADIENT_STOP structures.

ID2D1GradientStopCollection* m_pGradientStops;
