Detailed Description

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

Member Function Documentation

cleanup()

static 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()

static 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()

static 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
