Detailed Description

efficient description of an image stencil

vtkImageStencilData describes an image stencil in a manner which is efficient both in terms of speed and storage space. The stencil extents are stored for each x-row across the image (multiple extents per row if necessary) and can be retrieved via the GetNextExtent() method.

◆ PrintSelf()

void vtkImageStencilData::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 vtkDataObject.

◆ Initialize()

void vtkImageStencilData::Initialize ( )

Restore data object to initial state,.

Reimplemented from vtkDataObject.

◆ DeepCopy()

void vtkImageStencilData::DeepCopy ( vtkDataObject * o )

overridevirtual

Reimplemented from vtkDataObject.

◆ ShallowCopy()

void vtkImageStencilData::ShallowCopy ( vtkDataObject * src )

overridevirtual

Shallow and Deep copy.

These copy the data, but not any of the pipeline connections.

Reimplemented from vtkDataObject.

◆ InternalImageStencilDataCopy()

void vtkImageStencilData::InternalImageStencilDataCopy ( vtkImageStencilData * s )

◆ GetDataObjectType()

int vtkImageStencilData::GetDataObjectType ( )

inlineoverridevirtual

Get the data type as an integer (this will return VTK_DATA_OBJECT for now, maybe a proper type constant will be reserved later).

Reimplemented from vtkDataObject.

Definition at line 53 of file vtkImageStencilData.h.

◆ GetExtentType()

int vtkImageStencilData::GetExtentType ( )

inlineoverridevirtual

The extent type is 3D, just like vtkImageData.

Reimplemented from vtkDataObject.

Definition at line 58 of file vtkImageStencilData.h.

◆ GetNextExtent()

int vtkImageStencilData::GetNextExtent	(	int &	r1,
		int &	r2,
		int	xMin,
		int	xMax,
		int	yIdx,
		int	zIdx,
		int &	iter
	)

Given the total output x extent [xMin,xMax] and the current y, z indices, return each sub-extent [r1,r2] that lies within within the unclipped region in sequence.

A value of '0' is returned if no more sub-extents are available. The variable 'iter' must be initialized to zero before the first call, unless you want the complementary sub-extents in which case you must initialize 'iter' to -1. The variable 'iter' is used internally to keep track of which sub-extent should be returned next.

◆ IsInside()

int vtkImageStencilData::IsInside	(	int	xIdx,
		int	yIdx,
		int	zIdx
	)

Checks if an image index is inside the stencil.

Even though GetNextExtent and the vtkImageStencilIterator are faster if every voxel in the volume has to be checked, IsInside provides an efficient alternative for if just a single voxel has to be checked.

◆ InsertNextExtent()

void vtkImageStencilData::InsertNextExtent	(	int	r1,
		int	r2,
		int	yIdx,
		int	zIdx
	)

This method is used by vtkImageStencilDataSource to add an x sub extent [r1,r2] for the x row (yIdx,zIdx).

The specified sub extent must not intersect any other sub extents along the same x row. As well, r1 and r2 must both be within the total x extent [Extent[0],Extent[1]].

◆ InsertAndMergeExtent()

void vtkImageStencilData::InsertAndMergeExtent	(	int	r1,
		int	r2,
		int	yIdx,
		int	zIdx
	)

Similar to InsertNextExtent, except that the extent (r1,r2) at yIdx, zIdx is merged with other extents, (if any) on that row.

So a unique extent may not necessarily be added. For instance, if an extent [5,11] already exists adding an extent, [7,9] will not affect the stencil. Likewise adding [10, 13] will replace the existing extent with [5,13].

◆ RemoveExtent()

void vtkImageStencilData::RemoveExtent	(	int	r1,
		int	r2,
		int	yIdx,
		int	zIdx
	)

Remove the extent from (r1,r2) at yIdx, zIdx.
