Detailed Description

Read nrrd files file system.

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

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 vtkImageReader.

Reimplemented in vtkPNrrdReader.

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 in vtkPNrrdReader.

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageReader.

◆ RequestData()

int vtkNrrdReader::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

This is called in response to a REQUEST_DATA request from the executive.

Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.
