CDXBnds::CDXBnds

---

CDXBnds Class

Constructs an uninitialized CDXBnds object.

Syntax

CDXBnds();

Return Value

No return value.

Remarks

The default constructor sets the object to DXBT_DISCRETE and calls the SetEmpty method.

See Also

CDXBnds::SetEmpty

CDXBnds::CDXBnds( BOOL bInit )

---

CDXBnds Class

Constructs and conditionally initializes the data object.

Syntax

CDXBnds(
	 BOOL bInit 
);

Parameters

bInit

[in] TRUE specifies that the object should be set to empty. FALSE specifies that no initialization action should be taken.

Return Value

No return value.

Remarks

Initializing with FALSE improves performance, if you know the next operation will be used to set the bounds (for example, by calling the IDXSurfaceModifier::SetBounds method).

CDXBnds::CDXBnds( const DXBNDS &Other )

---

CDXBnds Class

Copies the specified bounds and converts the type, if necessary.

Syntax

CDXBnds(
	const DXBNDS &Other 
);

Parameters

Other

[in] DXBNDS structure to use for initialization.

Return Value

No return value.

Remarks

If Other is not of the same union type as the template class, the constructor converts it. For example, Other can be DXBT_CONTINUOUS, and the template can be DXBT_DISCRETE.

CDXBnds::CDXBnds( const CDXB_C &Other )

---

CDXBnds Class

Creates a CDXBnds object by copying an existing object.

Syntax

CDXBnds(
	const CDXB_C &Other 
);

Parameters

Other

[in] Bounds class to use for initialization.

Return Value

No return value.

CDXBnds::CDXBnds( const RECT &Rect )

---

CDXBnds Class

Initializes the data object, using the specified rectangle to set the x and y bounds.

Syntax

CDXBnds(
	const RECT &Rect 
);

Parameters

Rect

[in] Rectangle to use for initialization.

Return Value

No return value.

Remarks

The minimum values for the z and t dimensions are set to zero. The maximum values are set to one.

CDXBnds::CDXBnds( TYPE Width, TYPE Height)

---

CDXBnds Class

Initializes the data object, using the specified width and height to set the x and y bounds.

Syntax

CDXBnds(
	TYPE Width,
	TYPE Height
);

Parameters

Width

[in] Width of the x-dimension.

Height

[in] Width of the y-dimension.

Return Value

No return value.

Remarks

The minimum values for all dimensions are set to zero. The maximum values for z and t are set to one.

CDXBnds::CDXBnds( IDXSurface *pSurface, HRESULT &hr )

---

CDXBnds Class

Initializes the data object with the bounds of the specified surface.

Syntax

CDXBnds(
	IDXSurface *pSurface,
	HRESULT &hr
);

Parameters

pSurface

[in] Pointer to a surface from which to acquire the bounds.

hr

[out] HRESULT return code from calling the IDXSurface::GetBounds method.

Return Value

See the return codes for IDXSurface::GetBounds.

CDXBnds::CDXBnds( IDirect3DRMMeshBuilder3 *pMesh, HRESULT &hr )

---

CDXBnds Class

Initializes the data object with the bounds of the specified Direct3DRMMeshBuilder3 object.

Syntax

CDXBnds(
	IDirect3DRMMeshBuilder3 *pMesh,
	HRESULT &hr
);

Parameters

pMesh

[in] Pointer to a mesh from which to acquire the bounds.

hr

[out] HRESULT return code from calling the IDirect3DRMMeshBuilder3::GetBox method.

Return Value

See the return codes for IDirect3DRMMeshBuilder3::GetBox.

CDXBnds::CDXBnds( const CDXV_C &VecPoint )

---

CDXBnds Class

Creates a CDXBnds object from a CDXVec object.

Syntax

CDXBnds(
	const CDXV_C &VecPoint 
);

Parameters

VecPoint

[in] Vector class to use for initialization.

Return Value

No return value.

CDXBnds::Copy( const DXBNDS &Other )

---

CDXBnds Class

Copies the specified bounds and converts the type, if necessary.

Syntax

Copy(
	const DXBNDS &Other 
);

Parameters

Other

[in] DXBNDS structure to use for initialization.

Return Value

No return value.

Remarks

If Other is not of the same union type as the template class, the constructor converts. For example, Other can be DXBT_CONTINUOUS and the template can be DXBT_DISCRETE.

CDXBnds::Copy( const CDXB_C &Other )

---

CDXBnds Class

Performs a simple copy operation.

Syntax

Copy(
	const CDXB_C &Other 
);

Parameters

Other

[in] Bounds class to use for initialization.

Return Value

No return value.
