bool itk::MetaImageIO::CanReadFile ( const char * )

overridevirtual

Determine the file type. Returns true if this ImageIO can read the file specified.

Implements itk::ImageIOBase.

bool itk::MetaImageIO::CanStreamRead ( )

inlineoverridevirtual

Determine if the ImageIO can stream reading from this file. Only time cannot stream read/write is if compression is used. CanRead must be called prior to this function.

Reimplemented from itk::ImageIOBase.

Definition at line 127 of file itkMetaImageIO.h.

bool itk::MetaImageIO::CanStreamWrite ( )

inlineoverridevirtual

Determine if the ImageIO can stream writing to this file. Only time cannot stream read/write is if compression is used. Assumes file passes a CanRead call and its pixels are of the same type as the template of the writer. Can verify by first calling CanRead and then CanStreamRead prior to calling CanStreamWrite.

Reimplemented from itk::ImageIOBase.

Definition at line 142 of file itkMetaImageIO.h.

bool itk::MetaImageIO::CanWriteFile ( const char * )

overridevirtual

Determine the file type. Returns true if this ImageIO can write the file specified.

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::MetaImageIO::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.

ImageIORegion itk::MetaImageIO::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requested ) const

overridevirtual

Method for supporting streaming. Given a requested region, calculate what could be the region that we can read from the file. This is called the streamable region, which will be smaller than the LargestPossibleRegion and greater or equal to the RequestedRegion

Reimplemented from itk::ImageIOBase.

unsigned int itk::MetaImageIO::GetActualNumberOfSplitsForWriting	(	unsigned int	numberOfRequestedSplits,
		const ImageIORegion &	pasteRegion,
		const ImageIORegion &	largestPossibleRegion
	)

overridevirtual

Before this method is called all the configuration will be done, that is Streaming/PasteRegion/Compression/Filename etc If pasting is being used the number of requested splits is for that region not the largest. The derived ImageIO class should verify that the file is capable of being written with this configuration. If pasted is enabled and is not support or does not work with the file, then an excepetion should be thrown.

The default implementation depends on CanStreamWrite. If false then 1 is returned (unless pasting is indicated), so that the whole file will be updated in one region. If true then its assumed that any arbitrary region can be written to any file. So the users request will be respected. If a derived class has more restictive conditions then they should be checked

Reimplemented from itk::ImageIOBase.

static unsigned int itk::MetaImageIO::GetDefaultDoublePrecision ( )

static

Set the default precision when writing out the MetaImage header. MetaImage header contains values stored in memory as double, use this precision when writing out the value. The precision should only be defined in the range [0, 17] since a value of 17 will make the conversion of a double floating-point to text and back exact. This function is not thread safe. Default value after static initialization is 17.

MetaImage* itk::MetaImageIO::GetMetaImagePointer ( )

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

virtual

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

ImageIORegion itk::MetaImageIO::GetSplitRegionForWriting	(	unsigned int	ithPiece,
		unsigned int	numberOfActualSplits,
		const ImageIORegion &	pasteRegion,
		const ImageIORegion &	largestPossibleRegion
	)

overridevirtual

returns the ith IORegion

numberOfActualSplits should be the value returned from GetActualNumberOfSplitsForWriting with the same parameters

Derieved classes should overload this method to return a compatible region

Reimplemented from itk::ImageIOBase.

virtual unsigned int itk::MetaImageIO::GetSubSamplingFactor ( ) const

virtual

Determing the subsampling factor in case we want a coarse version of the image/

Warning: this is only used when streaming is on.

itk::MetaImageIO::itkGetGlobalDeclarationMacro	(	unsigned	int,
		DefaultDoublePrecision
	)

private

Only used to synchronize the global variable across static libraries.

static Pointer itk::MetaImageIO::New ( )

static

Method for creation through the object factory.

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

overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

void itk::MetaImageIO::ReadImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.

virtual void itk::MetaImageIO::SetDataFileName ( const char * filename )

virtual

Set the filename for the Data file. Setting this will make the Writer to use the non-Local mode and save header and data in independent files

static void itk::MetaImageIO::SetDefaultDoublePrecision ( unsigned int precision )

static

Set the default precision when writing out the MetaImage header. MetaImage header contains values stored in memory as double, use this precision when writing out the value. The precision should only be defined in the range [0, 17] since a value of 17 will make the conversion of a double floating-point to text and back exact. This function is not thread safe. Default value after static initialization is 17.

virtual void itk::MetaImageIO::SetDoublePrecision ( unsigned int precision )

inlinevirtual

set the precision in the MetaImage member

Definition at line 101 of file itkMetaImageIO.h.

virtual void itk::MetaImageIO::SetSubSamplingFactor ( unsigned int _arg )

virtual

Determing the subsampling factor in case we want a coarse version of the image/

Warning: this is only used when streaming is on.

bool itk::MetaImageIO::SupportsDimension ( unsigned long )

inlineoverridevirtual

The different types of ImageIO's can support data of varying dimensionality. For example, some file formats are strictly 2D while others can support 2D, 3D, or even n-D. This method returns true/false as to whether the ImageIO can support the dimension indicated.

Reimplemented from itk::ImageIOBase.

Definition at line 62 of file itkMetaImageIO.h.

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

overridevirtual

Writes the data to disk from the memory buffer provided. Make sure that the IORegions has been set properly.

Implements itk::ImageIOBase.

void itk::MetaImageIO::WriteImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.
