Detailed Description

abstract class for mapping images to the screen

vtkImageMapper3D is a mapper that will draw a 2D image, or a slice of a 3D image. The slice plane can be set automatically follow the camera, so that it slices through the focal point and faces the camera.

Thanks:: Thanks to David Gobbi at the Seaman Family MR Centre and Dept. of Clinical Neurosciences, Foothills Medical Centre, Calgary, for providing this class.

static vtkTypeBool vtkImageMapper3D::IsTypeOf ( const char * type )

static

virtual vtkTypeBool vtkImageMapper3D::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkAbstractMapper3D.

Reimplemented in vtkImageResliceMapper, vtkImageSliceMapper, and vtkOpenGLImageSliceMapper.

static vtkImageMapper3D* vtkImageMapper3D::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkImageMapper3D::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkAbstractMapper3D.

Reimplemented in vtkImageResliceMapper, vtkImageSliceMapper, and vtkOpenGLImageSliceMapper.

vtkImageMapper3D* vtkImageMapper3D::NewInstance ( ) const

void vtkImageMapper3D::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkAbstractMapper3D.

Reimplemented in vtkImageResliceMapper, vtkImageSliceMapper, and vtkOpenGLImageSliceMapper.

virtual void vtkImageMapper3D::Render	(	vtkRenderer *	renderer,
		vtkImageSlice *	prop
	)

pure virtual

This should only be called by the renderer.

Implemented in vtkImageResliceMapper, vtkImageSliceMapper, and vtkOpenGLImageSliceMapper.

void vtkImageMapper3D::ReleaseGraphicsResources ( vtkWindow * )

overridepure virtual

Release any graphics resources that are being consumed by this mapper.

The parameter window is used to determine which graphic resources to release.

Reimplemented from vtkAbstractMapper.

Implemented in vtkImageResliceMapper, vtkImageSliceMapper, and vtkOpenGLImageSliceMapper.

void vtkImageMapper3D::SetInputData ( vtkImageData * input )

The input data for this mapper.

vtkImageData* vtkImageMapper3D::GetInput ( )

The input data for this mapper.

vtkDataSet* vtkImageMapper3D::GetDataSetInput ( )

The input data for this mapper.

vtkDataObject* vtkImageMapper3D::GetDataObjectInput ( )

The input data for this mapper.

virtual void vtkImageMapper3D::SetBorder ( vtkTypeBool )

virtual

Instead of displaying the image only out to the image bounds, include a half-voxel border around the image.

Within this border, the image values will be extrapolated rather than interpolated.

virtual void vtkImageMapper3D::BorderOn ( )

virtual

Instead of displaying the image only out to the image bounds, include a half-voxel border around the image.

Within this border, the image values will be extrapolated rather than interpolated.

virtual void vtkImageMapper3D::BorderOff ( )

virtual

Instead of displaying the image only out to the image bounds, include a half-voxel border around the image.

Within this border, the image values will be extrapolated rather than interpolated.

virtual vtkTypeBool vtkImageMapper3D::GetBorder ( )

virtual

Instead of displaying the image only out to the image bounds, include a half-voxel border around the image.

Within this border, the image values will be extrapolated rather than interpolated.

virtual void vtkImageMapper3D::SetBackground ( vtkTypeBool )

virtual

Instead of rendering only to the image border, render out to the viewport boundary with the background color.

The background color will be the lowest color on the lookup table that is being used for the image.

virtual void vtkImageMapper3D::BackgroundOn ( )

virtual

Instead of rendering only to the image border, render out to the viewport boundary with the background color.

The background color will be the lowest color on the lookup table that is being used for the image.

virtual void vtkImageMapper3D::BackgroundOff ( )

virtual

Instead of rendering only to the image border, render out to the viewport boundary with the background color.

The background color will be the lowest color on the lookup table that is being used for the image.

virtual vtkTypeBool vtkImageMapper3D::GetBackground ( )

virtual

Instead of rendering only to the image border, render out to the viewport boundary with the background color.

The background color will be the lowest color on the lookup table that is being used for the image.

virtual void vtkImageMapper3D::SetSliceAtFocalPoint ( vtkTypeBool )

virtual

Automatically set the slice position to the camera focal point.
