#include <itkJPEG2000ImageIO.h>

Detailed Description

Supports for the JPEG2000 file format based on openjpeg.

JPEG2000 offers a large collection of interesting features including: compression (lossless and lossy), streaming, multi-channel images.

This code was contributed in the Insight Journal paper: "Support for Streaming the JPEG2000 File Format" by Mosaliganti K., Ibanez L., Megason S https://doi.org/10.54294/bo53br

◆ CanReadFile()

bool itk::JPEG2000ImageIO::CanReadFile ( const char * )

overridevirtual

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

Implements itk::ImageIOBase.

◆ CanStreamWrite()

bool itk::JPEG2000ImageIO::CanStreamWrite ( )

overridevirtual

Currently JPEG2000 does not support streamed writing

These methods are re-overridden to not support streaming for now...

Reimplemented from itk::ImageIOBase.

◆ CanWriteFile()

bool itk::JPEG2000ImageIO::CanWriteFile ( const char * )

overridevirtual

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

Implements itk::ImageIOBase.

◆ ComputeRegionInTileBoundaries()

◆ CreateAnother()

virtual::itk::LightObject::Pointer itk::JPEG2000ImageIO::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::LightObject.

◆ GenerateStreamableReadRegionFromRequestedRegion()

ImageIORegion itk::JPEG2000ImageIO::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requestedRegion ) const

overridevirtual

Method for supporting streaming. Given a requested region, determine 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.

◆ GetHeaderSize()

SizeType itk::JPEG2000ImageIO::GetHeaderSize ( ) const

overridevirtual

Method required by the base class StreamingImageIOBase

Implements itk::StreamingImageIOBase.

◆ New()

static Pointer itk::JPEG2000ImageIO::New ( )

static

Method for creation through the object factory.

◆ PrintSelf()

void itk::JPEG2000ImageIO::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.

◆ Read()

void itk::JPEG2000ImageIO::Read ( void * buffer )

overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

◆ ReadImageInformation()

void itk::JPEG2000ImageIO::ReadImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.

◆ SetTileSize()

void itk::JPEG2000ImageIO::SetTileSize	(	int	x,
		int	y )

Define the tile size to use when writing out an image.

◆ Write()

void itk::JPEG2000ImageIO::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.

◆ WriteImageInformation()

void itk::JPEG2000ImageIO::WriteImageInformation ( )

overridevirtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.
