Detailed Description

Initiates streaming on image data.

To satisfy a request, this filter calls update on its input many times with smaller update extents. All processing up stream streams smaller pieces.

Member Function Documentation

vtkImageDataStreamer* vtkImageDataStreamer::New ( ) [static]

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

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

Reimplemented from vtkImageToImageFilter.
Reimplemented in vtkMemoryLimitImageDataStreamer.

int vtkImageDataStreamer::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 vtkImageToImageFilter.
Reimplemented in vtkMemoryLimitImageDataStreamer.

virtual int vtkImageDataStreamer::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 vtkImageToImageFilter.
Reimplemented in vtkMemoryLimitImageDataStreamer.

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

Reimplemented from vtkImageToImageFilter.
Reimplemented in vtkMemoryLimitImageDataStreamer.

void vtkImageDataStreamer::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 vtkImageToImageFilter.
Reimplemented in vtkMemoryLimitImageDataStreamer.

virtual void vtkImageDataStreamer::SetNumberOfStreamDivisions ( int ) [virtual]

Set how many pieces to divide the input into. void SetNumberOfStreamDivisions(int num); int GetNumberOfStreamDivisions();

virtual int vtkImageDataStreamer::GetNumberOfStreamDivisions ( ) [virtual]

Set how many pieces to divide the input into. void SetNumberOfStreamDivisions(int num); int GetNumberOfStreamDivisions();

virtual void vtkImageDataStreamer::Update ( ) [inline, virtual]

Bring object up-to-date before execution. Update() checks modified time against last execution time, and re-executes object if necessary.
Reimplemented from vtkSource.
Definition at line 63 of file vtkImageDataStreamer.h.
References vtkAlgorithm::Update().

virtual void vtkImageDataStreamer::UpdateWholeExtent ( ) [inline, virtual]

Like update, but make sure the update extent is the whole extent in the output.
Reimplemented from vtkSource.
Definition at line 64 of file vtkImageDataStreamer.h.
References vtkAlgorithm::UpdateWholeExtent().

virtual void vtkImageDataStreamer::SetExtentTranslator ( vtkExtentTranslator * ) [virtual]

Get the extent translator that will be used to split the requests

virtual vtkExtentTranslator* vtkImageDataStreamer::GetExtentTranslator ( ) [virtual]

Get the extent translator that will be used to split the requests

int vtkImageDataStreamer::ProcessRequest ( vtkInformation * ,

vtkInformationVector * ,

vtkInformationVector *

) [virtual]

Transform pipeline requests from executives into old-style pipeline calls. This works with the vtkStreamingDemandDrivenPipeline executive to maintain backward compatibility for filters written as subclasses of vtkSource.
Reimplemented from vtkSource.
Reimplemented in vtkMemoryLimitImageDataStreamer.

virtual int vtkImageDataStreamer::FillInputPortInformation ( int port,

vtkInformation * info

) [protected, virtual]

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

virtual int vtkImageDataStreamer::FillOutputPortInformation ( int port,

vtkInformation * info

) [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 vtkImageSource.
