bool itk::MGHImageIO::CanReadFile ( const char * FileNameToRead )

overridevirtual

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

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.

bool itk::MGHImageIO::CanWriteFile ( const char * FileNameToWrite )

overridevirtual

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

Parameters

FileNameToWrite The name of the file to test for writing.

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

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

Implements itk::ImageIOBase.

void itk::MGHImageIO::CloseFile ( )

private

virtual::itk::LightObject::Pointer itk::MGHImageIO::CreateAnother ( ) 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.

unsigned int itk::MGHImageIO::GetComponentSize ( ) const

overrideprivatevirtual

Compute the size (in bytes) of the components of a pixel. For example, and RGB pixel of unsigned char would have a component size of 1 byte. This method can be invoked only after the component type is set.

Reimplemented from itk::ImageIOBase.

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

virtual

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

std::string itk::MGHImageIO::GetOrientation ( itk::Matrix< double > directions )

private

bool itk::MGHImageIO::IsCompressedFilename ( const std::string fname )

private

check if a filename is for a compressed file

static Pointer itk::MGHImageIO::New ( )

static

Method for creation through the object factory.

void itk::MGHImageIO::OpenFile ( )

private

void itk::MGHImageIO::PermuteFrameValues	(	const void *	buffer,
		char *	tempmemory
	)

private

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

overrideprotectedvirtual

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::ImageIOBase.

void itk::MGHImageIO::Read ( void * buffer )

overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

void itk::MGHImageIO::ReadImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.

void itk::MGHImageIO::ReadVolumeHeader ( )

void itk::MGHImageIO::Write ( const void * buffer )

overridevirtual

Implements itk::ImageIOBase.

void itk::MGHImageIO::WriteData ( const void * buffer )

private

void itk::MGHImageIO::WriteHeader ( )

private

examines the direction cosines and creates encapsulation data

void itk::MGHImageIO::WriteImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.
