CD2DBrush
Header: afxrendertarget.h
The destructor. Called when a D2D brush object is being destroyed.
virtual ~CD2DBrush();
Attaches existing resource interface to the object.
void Attach(ID2D1Brush* pResource);pResource
Existing resource interface. Cannot be NULL.
Constructs a CD2DBrush object.
CD2DBrush(
CRenderTarget* pParentTarget,
CD2DBrushProperties* pBrushProperties = NULL,
BOOL bAutoDestroy = TRUE);
pParentTarget
A pointer to the render target.
pBrushProperties
A pointer to the opacity and transformation of a brush.
bAutoDestroy
Indicates that the object will be destroyed by owner (pParentTarget).
Destroys a CD2DBrush object.
virtual void Destroy();
Detaches resource interface from the object.
ID2D1Brush* Detach();
Pointer to detached resource interface.
Returns ID2D1Brush interface
ID2D1Brush* Get();
Pointer to an ID2D1Brush interface or NULL if object is not initialized yet.
Gets the degree of opacity of this brush
FLOAT GetOpacity() const;
A value between zero and 1 that indicates the opacity of the brush. This value is a constant multiplier that linearly scales the alpha value of all pixels filled by the brush. The opacity values are clamped in the range 0 to 1 before they are multiplied together.
Gets the current transform of the render target
void GetTransform(D2D1_MATRIX_3X2_F* transform) const;transform
When this returns, contains the current transform of the render target. This parameter is passed uninitialized.
Checks resource validity
virtual BOOL IsValid() const;
TRUE if resource is valid; otherwise FALSE.
Stores a pointer to an ID2D1Brush object.
ID2D1Brush* m_pBrush;
Brush properties.
CD2DBrushProperties* m_pBrushProperties;
Returns ID2D1Brush interface
operator ID2D1Brush*();
Pointer to an ID2D1Brush interface or NULL if object is not initialized yet.
Sets the degree of opacity of this brush
void SetOpacity(FLOAT opacity);opacity
A value between zero and 1 that indicates the opacity of the brush. This value is a constant multiplier that linearly scales the alpha value of all pixels filled by the brush. The opacity values are clamped in the range 0 to 1 before they are multiplied together.
Applies the specified transform to the render target, replacing the existing transformation. All subsequent drawing operations occur in the transformed space.
void SetTransform(const D2D1_MATRIX_3X2_F* transform);transform
The transform to apply to the render target
