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 http://hdl.handle.net/10380/3187 http://www.insight-journal.org/browse/publication/741

Member Function Documentation

virtual bool itk::JPEG2000ImageIO::CanReadFile ( const char * ) [virtual]

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

Implements itk::ImageIOBase.

virtual bool itk::JPEG2000ImageIO::CanStreamWrite ( void ) [virtual]

Currently JPEG2000 does not support streamed writing

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

Reimplemented from itk::StreamingImageIOBase.

virtual bool itk::JPEG2000ImageIO::CanWriteFile ( const char * ) [virtual]

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

Implements itk::ImageIOBase.

void itk::JPEG2000ImageIO::ComputeRegionInTileBoundaries	(	unsigned int	dimension,
		SizeValueType	tileSize,
		ImageIORegion &	streamableRegion
	)		const `[private]`

virtual::itk::LightObject::Pointer itk::JPEG2000ImageIO::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::JPEG2000ImageIO::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion & requested ) const [virtual]

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::StreamingImageIOBase.

virtual SizeType itk::JPEG2000ImageIO::GetHeaderSize ( void ) const [virtual]

Method required by the base class StreamingImageIOBase

Implements itk::StreamingImageIOBase.

virtual const char* itk::JPEG2000ImageIO::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::StreamingImageIOBase.

static Pointer itk::JPEG2000ImageIO::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::LightProcessObject.

void itk::JPEG2000ImageIO::operator= ( const Self & ) [private]

This method causes the filter to generate its output.

Reimplemented from itk::StreamingImageIOBase.

void itk::JPEG2000ImageIO::PrintSelf	(	std::ostream &	os,
		Indent	indent
	)		const `[protected, virtual]`

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::JPEG2000ImageIO::Read ( void * buffer ) [virtual]

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

virtual void itk::JPEG2000ImageIO::ReadImageInformation ( ) [virtual]

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.
