Detailed Description

Read nrrd files efficiently from parallel file systems (and reasonably well elsewhere).

vtkPNrrdReader is a subclass of vtkNrrdReader that will read Nrrd format header information of the image before reading the data. This means that the reader will automatically set information like file dimensions.

Bug:: There are several limitations on what type of nrrd files we can read. This reader only supports nrrd files in raw format. Other encodings like ascii and hex will result in errors. When reading in detached headers, this only supports reading one file that is detached.

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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkNrrdReader.

virtual void vtkPNrrdReader::PrintSelf	(	ostream &	os,

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 vtkNrrdReader.

virtual vtkMultiProcessController* vtkPNrrdReader::GetController ( )

virtual

Get/set the multi process controller to use for coordinated reads. By default, set to the global controller.

virtual void vtkPNrrdReader::SetController ( vtkMultiProcessController * )

virtual

Get/set the multi process controller to use for coordinated reads. By default, set to the global controller.

virtual int vtkPNrrdReader::ReadHeader ( )

protectedvirtual

Reimplemented from vtkNrrdReader.

virtual int vtkPNrrdReader::ReadHeader ( vtkCharArray * headerBuffer )

protectedvirtual

Reimplemented from vtkNrrdReader.

int vtkPNrrdReader::GetDataScalarTypeSize ( )

protected

Returns the size, in bytes of the scalar data type (GetDataScalarType).

virtual void vtkPNrrdReader::PartitionController ( const int extent[6] )

protectedvirtual

Break up the controller based on the files each process reads. Each group comprises the processes that read the same files in the same order. this->GroupedController is set to the group for the current process.

virtual unsigned long vtkPNrrdReader::GetHeaderSize ( vtkMPIOpaqueFileHandle & file )

protectedvirtual

Get the header size of the given open file. This should be used in liu of the GetHeaderSize methods of the superclass.

virtual void vtkPNrrdReader::SetupFileView	(	vtkMPIOpaqueFileHandle &	file,
		const int	extent[6]
	)

protectedvirtual

Set up a "view" on the open file that will allow you to read the 2D or 3D subarray from the file in one read. Once you call this method, the file will look as if it contains only the data the local process needs to read in.

virtual void vtkPNrrdReader::ReadSlice	(	int	slice,
		const int	extent[6],
		void *	buffer
	)

protectedvirtual

Given a slice of the data, open the appropriate file, read the data into given buffer, and close the file. For three dimensional data, always use "slice" 0. Make sure the GroupedController is properly created before calling this using the PartitionController method.

virtual void vtkPNrrdReader::TransformData ( vtkImageData * data )

protectedvirtual

Transform the data from the order read from a file to the order to place in the output data (as defined by the transform).

void vtkPNrrdReader::SetGroupedController ( vtkMultiProcessController * )

protected

A group of processes that are reading the same file (as determined by PartitionController.

virtual void vtkPNrrdReader::ExecuteDataWithInformation	(	vtkDataObject *	output,
		vtkInformation *	outInfo
	)

protectedvirtual

This is a convenience method that is implemented in many subclasses instead of RequestData. It is called by RequestData.

Reimplemented from vtkImageReader.
