Member Function Documentation

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

virtual

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

Implements itk::ImageIOBase.

virtual bool itk::MetaImageIO::CanStreamRead ( void )

inlinevirtual

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 120 of file itkMetaImageIO.h.

virtual bool itk::MetaImageIO::CanStreamWrite ( void )

inlinevirtual

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 135 of file itkMetaImageIO.h.

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

virtual

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

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::MetaImageIO::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 ImageIORegion itk::MetaImageIO::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requested ) const

virtual

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.

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

virtual

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.

MetaImage* itk::MetaImageIO::GetMetaImagePointer ( void )

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

virtual

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

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

virtual

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.

static Pointer itk::MetaImageIO::New ( )

static

Method for creation through the object factory.

Reimplemented from itk::LightProcessObject.

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

private

This method causes the filter to generate its output.

Reimplemented from itk::ImageIOBase.

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

protectedvirtual

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

Warning:: this is only used when streaming is on.

Reimplemented from itk::ImageIOBase.

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

virtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

virtual void itk::MetaImageIO::ReadImageInformation ( )

virtual

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

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

inlinevirtual

set the precision in the MetaImage member

Definition at line 94 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.

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

inlinevirtual

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 55 of file itkMetaImageIO.h.

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

virtual

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

Implements itk::ImageIOBase.

virtual void itk::MetaImageIO::WriteImageInformation ( )

virtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.
