Detailed Description

Superclass of binary file readers.

vtkImageReader2 is a parent class for many VTK image readers. It was written to simplify the interface of vtkImageReader. It can also be used directly to read data without headers (raw). It is a good super class for streaming readers that do not require a mask or transform on the data. An example of reading a raw file is shown below:

 vtkSmartPointer<vtkImageReader2> reader =
  vtkSmartPointer<vtkImageReader2>::New();
reader->SetFilePrefix(argv[1]);
reader->SetDataExtent(0, 63, 0, 63, 1, 93);
reader->SetDataSpacing(3.2, 3.2, 1.5);
reader->SetDataOrigin(0.0, 0.0, 0.0);
reader->SetDataScalarTypeToUnsignedShort();
reader->SetDataByteOrderToLittleEndian();
reader->UpdateWholeExtent();

◆ PrintSelf()

void vtkImageReader2::PrintSelf	(	ostream &	os,
		vtkIndent	indent )

overridevirtual

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 vtkImageAlgorithm.

Reimplemented in vtkJPEGReader, vtkMedicalImageReader2, vtkMetaImageReader, vtkMINCImageReader, vtkMPIImageReader, vtkNIFTIImageReader, vtkNrrdReader, vtkOMETIFFReader, vtkOpenSlideReader, vtkPNGReader, vtkPNMReader, vtkPNrrdReader, vtkSLCReader, vtkTGAReader, and vtkTIFFReader.

◆ SetFileName()

virtual void vtkImageReader2::SetFileName ( const char * )

virtual

Specify file name for the image file.

If the data is stored in multiple files, then use SetFileNames or SetFilePrefix instead.

Reimplemented in vtkDICOMImageReader, and vtkMINCImageReader.

◆ vtkGetFilePathMacro() [1/4]

vtkImageReader2::vtkGetFilePathMacro ( FileName )

Specify file name for the image file.

If the data is stored in multiple files, then use SetFileNames or SetFilePrefix instead.

◆ SetFileNames()

virtual void vtkImageReader2::SetFileNames ( vtkStringArray * )

virtual

Specify a list of file names.

Each file must be a single slice, and each slice must be of the same size. The files must be in the correct order. Use SetFileName when reading a volume (multiple slice), since DataExtent will be modified after a SetFileNames call.

◆ GetFileNames()

virtual vtkStringArray * vtkImageReader2::GetFileNames ( )

virtual

Specify a list of file names.

Each file must be a single slice, and each slice must be of the same size. The files must be in the correct order. Use SetFileName when reading a volume (multiple slice), since DataExtent will be modified after a SetFileNames call.

◆ vtkSetFilePathMacro()

vtkImageReader2::vtkSetFilePathMacro ( FilePrefix )

Specify file prefix for the image file or files.

This can be used in place of SetFileName or SetFileNames if the filenames follow a specific naming pattern, but you must explicitly set the DataExtent so that the reader will know what range of slices to load.

◆ vtkGetFilePathMacro() [2/4]

vtkImageReader2::vtkGetFilePathMacro ( FilePrefix )

Specify file prefix for the image file or files.

This can be used in place of SetFileName or SetFileNames if the filenames follow a specific naming pattern, but you must explicitly set the DataExtent so that the reader will know what range of slices to load.

◆ SetFilePattern()

virtual void vtkImageReader2::SetFilePattern ( const char * )

virtual

The std::format or printf style format string used to build filename from FilePrefix and slice number.

◆ vtkGetFilePathMacro() [3/4]

vtkImageReader2::vtkGetFilePathMacro ( FilePattern )

The std::format or printf style format string used to build filename from FilePrefix and slice number.

◆ SetStream()

virtual void vtkImageReader2::SetStream ( vtkResourceStream * )

virtual

Specify stream to read from When both Stream and Filename or FilePattern are set, it's left to the implementation to determine which one is used.

◆ GetStream()

virtual vtkResourceStream * vtkImageReader2::GetStream ( )

virtual

Specify stream to read from When both Stream and Filename or FilePattern are set, it's left to the implementation to determine which one is used.

◆ SetMemoryBuffer()

virtual void vtkImageReader2::SetMemoryBuffer ( const void * )

virtual

Specify the in memory image buffer.

May be used by a reader to allow the reading of an image from memory instead of from file. This should be reworked to use vtkResourceStream instead

◆ GetMemoryBuffer()

virtual const void * vtkImageReader2::GetMemoryBuffer ( )

virtual

Specify the in memory image buffer.

May be used by a reader to allow the reading of an image from memory instead of from file. This should be reworked to use vtkResourceStream instead

virtual

Specify the in memory image buffer length.
