Detailed Description

Class that defines how to read HDF5 file format. HDF5 IMAGE FILE FORMAT - As much information as I can determine from sourceforge.net/projects/HDF5lib.

Author: Kent Williams

HDF5 paths for elements in file

N is dimension of image
\/ITKVersion ITK Library Version string
\/HDFVersion HDF Version String
\/ITKImage Root Image Group
\/ITKImage\/<name> name is arbitrary, but to parallel Transform I/O keep an image in a subgroup. The idea is to parallel transform file structure.
\/ITKImage\/<name>\/Origin N-D point double
\/ITKImage\/<name>\/Directions N N-vectors double
\/ITKImage\/<name>\/Spacing N-vector double
\/ITKImage\/<name>\/Dimensions N-vector itk::SizeValueType
\/ITKImage\/<name>\/VoxelType String representing voxel type. This can be inferred from the VoxelData type info, but it makes the file more user friendly with respect to HDF5 viewers.
\/ITKImage\/<name>\/VoxelData multi-dim array of voxel data in the case of non-scalar voxel type, keep voxel components together, to make loading possible without
\/ITKImage\/<name>\/MetaData Group for storing metadata from MetaDataDictionary
\/ITKImage\/<name>\/MetaData\/<item-name> Dataset containing data for item-name in the MetaDataDictionary re-arrangement.

Member Function Documentation

virtual bool itk::HDF5ImageIO::CanReadFile ( const char * FileNameToRead )

virtual

Determine if the file can be read with this ImageIO implementation.

Author: Hans J Johnson

Parameters

FileNameToRead The name of the file to test for reading.

Postcondition: Sets classes ImageIOBase::m_FileName variable to be FileNameToWrite

Returns: Returns true if this ImageIO can read the file specified.

Implements itk::ImageIOBase.

virtual bool itk::HDF5ImageIO::CanWriteFile ( const char * FileNameToWrite )

virtual

Determine if the file can be written with this ImageIO implementation.

Parameters

FileNameToWrite The name of the file to test for writing.

Author: Hans J. Johnson

Postcondition: Sets classes ImageIOBase::m_FileName variable to be FileNameToWrite

Returns: Returns true if this ImageIO can write the file specified.

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::HDF5ImageIO::CreateAnother ( void ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightProcessObject.

virtual SizeType itk::HDF5ImageIO::GetHeaderSize ( void ) const

protectedvirtual

Returns the size of the header in the file.

Implements itk::StreamingImageIOBase.

virtual const char* itk::HDF5ImageIO::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::StreamingImageIOBase.

static Pointer itk::HDF5ImageIO::New ( )

static

void itk::HDF5ImageIO::operator= ( const Self & )

private

void itk::HDF5ImageIO::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const

protectedvirtual

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 itk::StreamingImageIOBase.

virtual void itk::HDF5ImageIO::Read ( void * buffer )

virtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

std::vector<std::vector<double> > itk::HDF5ImageIO::ReadDirections ( const std::string & path )

virtual void itk::HDF5ImageIO::ReadImageInformation ( )
