Detailed Description

representation for showing slices from a vtkImageData.

vtkImageSliceRepresentation is a representation for showing slices from an image dataset. Currently, it does not support composite datasets, however, we should be able to add such a support in future.

Member Function Documentation

static vtkImageSliceRepresentation* vtkImageSliceRepresentation::New ( ) [static]

Reimplemented from vtkDataRepresentation.

virtual const char* vtkImageSliceRepresentation::GetClassName ( ) [virtual]

Reimplemented from vtkPVDataRepresentation.

static int vtkImageSliceRepresentation::IsTypeOf ( const char * type ) [static]

Reimplemented from vtkPVDataRepresentation.

virtual int vtkImageSliceRepresentation::IsA ( const char * type ) [virtual]

Reimplemented from vtkPVDataRepresentation.

static vtkImageSliceRepresentation* vtkImageSliceRepresentation::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPVDataRepresentation.

void vtkImageSliceRepresentation::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Reimplemented from vtkPVDataRepresentation.

void vtkImageSliceRepresentation::SetColorAttributeType ( int type )

Methods to control scalar coloring. ColorAttributeType defines the attribute type.

void vtkImageSliceRepresentation::SetColorArrayName ( const char * name )

Pick the array to color with.

virtual int vtkImageSliceRepresentation::ProcessViewRequest	(	vtkInformationRequestKey *	request_type,
		vtkInformation *	inInfo,
		vtkInformation *	outInfo
	)		`[virtual]`

vtkAlgorithm::ProcessRequest() equivalent for rendering passes. This is typically called by the vtkView to request meta-data from the representations or ask them to perform certain tasks e.g. PrepareForRendering.

Reimplemented from vtkPVDataRepresentation.

virtual void vtkImageSliceRepresentation::MarkModified ( ) [virtual]

This needs to be called on all instances of vtkImageSliceRepresentation when the input is modified. This is essential since the geometry filter does not have any real-input on the client side which messes with the Update requests.

Reimplemented from vtkPVDataRepresentation.

virtual void vtkImageSliceRepresentation::SetVisibility ( bool val ) [virtual]

Get/Set the visibility for this representation. When the visibility of representation of false, all view passes are ignored. Overridden to propagate to the active representation.

Reimplemented from vtkPVDataRepresentation.

virtual void vtkImageSliceRepresentation::SetSlice ( unsigned int ) [virtual]

Get set the slice number to extract.

virtual unsigned int vtkImageSliceRepresentation::GetSlice ( ) [virtual]

Get set the slice number to extract.

virtual void vtkImageSliceRepresentation::SetSliceMode ( int ) [virtual]

Get/Set the direction in which to slice a 3D input data.

virtual int vtkImageSliceRepresentation::GetSliceMode ( ) [virtual]

Get/Set the direction in which to slice a 3D input data.

void vtkImageSliceRepresentation::SetOrientation	(	double	,
		double	,
		double
	)

void vtkImageSliceRepresentation::SetOrigin	(	double	,

void vtkImageSliceRepresentation::SetPickable ( int val )

void vtkImageSliceRepresentation::SetPosition	(	double	,

	)

void vtkImageSliceRepresentation::SetOpacity ( double val )

void vtkImageSliceRepresentation::SetLookupTable ( vtkScalarsToColors * val )

void vtkImageSliceRepresentation::SetMapScalars ( int val )

void vtkImageSliceRepresentation::SetUseXYPlane ( int val )

void vtkImageSliceRepresentation::UpdateSliceData ( vtkInformationVector ** ) [protected]

Extract the slice.

virtual int vtkImageSliceRepresentation::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)		`[protected, virtual]`

Fill input port information.

Reimplemented from vtkPassInputTypeAlgorithm.

virtual int vtkImageSliceRepresentation::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		`[protected, virtual]`

Subclasses should override this to connect inputs to the internal pipeline as necessary. Since most representations are "meta-filters" (i.e. filters containing other filters), you should create shallow copies of your input before connecting to the internal pipeline. The convenience method GetInternalOutputPort will create a cached shallow copy of a specified input for you. The related helper functions GetInternalAnnotationOutputPort, GetInternalSelectionOutputPort should be used to obtain a selection or annotation port whose selections are localized for a particular input data object.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkImageSliceRepresentation::AddToView ( vtkView * view ) [protected, virtual]

Adds the representation to the view. This is called from vtkView::AddRepresentation(). Subclasses should override this method. Returns true if the addition succeeds.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkImageSliceRepresentation::RemoveFromView ( vtkView * view ) [protected, virtual]

Removes the representation to the view. This is called from vtkView::RemoveRepresentation(). Subclasses should override this method. Returns true if the removal succeeds.

Reimplemented from vtkPVDataRepresentation.

virtual bool vtkImageSliceRepresentation::IsCached ( double cache_key ) [protected, virtual]

Overridden to check with the vtkPVCacheKeeper to see if the key is cached.

Reimplemented from vtkPVDataRepresentation.
