Detailed Description

helper class for clipping images

vtkImageStencilSource is a helper class for vtkImageToImageFilter classes. Given a clipping object such as a vtkImplicitFunction, it will set up a list of clipping extents for each x-row through the image data. The extents for each x-row can be retrieved via the GetNextExtent() method after the extent lists have been built with the BuildExtents() method. For large images, using clipping extents is much more memory efficient (and slightly more time-efficient) than building a mask. This class can be subclassed to allow clipping with objects other than vtkImplicitFunction.

Member Function Documentation

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

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

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

Reimplemented from vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

static int vtkImageStencilSource::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 vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

virtual int vtkImageStencilSource::IsA (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

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

Reimplemented from vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

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

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 vtkAlgorithm. Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

void vtkImageStencilSource::SetOutput (  vtkImageStencilData *  output  )

Get or set the output for this source.

vtkImageStencilData* vtkImageStencilSource::GetOutput (   )

virtual int vtkImageStencilSource::ProcessRequest (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [virtual]

see vtkAlgorithm for details Reimplemented from vtkAlgorithm.

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

Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil.

virtual int vtkImageStencilSource::RequestInformation (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [inline, protected, virtual]

Reimplemented in vtkPolyDataToImageStencil, vtkImageToImageStencil, and vtkImplicitFunctionToImageStencil. Definition at line 66 of file vtkImageStencilSource.h.

virtual int vtkImageStencilSource::RequestUpdateExtent (  vtkInformation *  , vtkInformationVector **  , vtkInformationVector *  )  [inline, protected, virtual]

Reimplemented in vtkImageToImageStencil. Definition at line 68 of file vtkImageStencilSource.h.

vtkImageStencilData* vtkImageStencilSource::AllocateOutputData (  vtkDataObject *  out, int *  updateExt )  [protected]

virtual int vtkImageStencilSource::FillOutputPortInformation (  int  , vtkInformation *  )  [protected, virtual]

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle. Reimplemented from vtkAlgorithm.
