Detailed Description

singleton class that registers decoders for all supported JPEG-LS processes.

Member Function Documentation

cleanup()

void DJLSDecoderRegistration::cleanup ( )

static

deregisters decoders.

Attention: Must not be called while other threads might still use the registered codecs, e.g. because they are currently decoding DICOM data sets through dcmdata.

getLibraryVersionString()

OFString DJLSDecoderRegistration::getLibraryVersionString ( )

static

get version information of the CharLS library.

Typical output format: "CharLS, Revision 55020 (modified)"

Returns

name and version number of the CharLS library

registerCodecs()

void DJLSDecoderRegistration::registerCodecs ( JLS_UIDCreation uidcreation = EJLSUC_default, JLS_PlanarConfiguration planarconfig = EJLSPC_restore, OFBool ignoreOffsetTable = OFFalse, OFBool forceSingleFragmentPerFrame = OFFalse )

static

registers decoder for all supported JPEG-LS processes.

If already registered, call is ignored unless cleanup() has been performed before.

Parameters

uidcreation	flag indicating whether or not a new SOP Instance UID should be assigned upon decompression.
planarconfig	flag indicating how planar configuration of color images should be encoded upon decompression.
ignoreOffsetTable	flag indicating whether to ignore the offset table when decompressing multiframe images
forceSingleFragmentPerFrame	while decompressing a multiframe image, assume one fragment per frame even if the JPEG data for some frame is incomplete
