Detailed Description

efficient description of an image stencil

Date:: 2002/11/12 19:21:02

Revision:: 1.8

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.

Member Function Documentation

vtkImageStencilData* vtkImageStencilData::New ( ) [static]

Reimplemented from vtkDataObject.

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

Reimplemented from vtkDataObject.

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

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkDataObject.

For legacy compatibility. Do not use.
Reimplemented from vtkDataObject.

void vtkImageStencilData::Initialize ( ) [virtual]

void vtkImageStencilData::DeepCopy ( vtkDataObject * o ) [virtual]

void vtkImageStencilData::InternalImageStencilDataCopy ( vtkImageStencilData * s )

int vtkImageStencilData::GetDataObjectType ( ) [inline, virtual]

Reimplemented from vtkDataObject.
Definition at line 66 of file vtkImageStencilData.h.
References VTK_DATA_OBJECT.

int vtkImageStencilData::GetExtentType ( ) [inline, virtual]

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.

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]].

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Propagate the update back up the pipeline, and perform the actual work of updating on the way down. When the propagate arrives at a port, block and wait for the asynchronous update to finish on the other side. This propagation may early terminate based on the PipelineMTime.
Reimplemented from vtkDataObject.

void vtkImageStencilData::TriggerAsynchronousUpdate ( ) [virtual]

WARNING: INTERNAL METHOD - NOT FOR GENERAL USE. THIS METHOD IS PART OF THE PIPELINE UPDATE FUNCTIONALITY. Propagate back up the pipeline for ports and trigger the update on the other side of the port to allow for asynchronous parallel processing in the pipeline. This propagation may early terminate based on the PipelineMTime.
