registers encoders for all supported JPEG-LS processes.

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

Parameters:
jpls_optionsEnabled enable/disable use of all five JPEG-LS parameters
jpls_t1 JPEG-LS parameter "Threshold 1" (used for quantization)
jpls_t2 JPEG-LS parameter "Threshold 2"
jpls_t3 JPEG-LS parameter "Threshold 3"
jpls_reset JPEG-LS parameter "RESET", i.e., value at which the counters A, B, and N are halved.
jpls_limit JPEG-LS parameter "LIMIT"
preferCookedEncoding true if the "cooked" lossless encoder should be preferred over the "raw" one
fragmentSize maximum fragment size (in kbytes) for compression, 0 for unlimited.
createOffsetTable create offset table during image compression
uidCreation mode for SOP Instance UID creation
convertToSC flag indicating whether image should be converted to Secondary Capture upon compression
jplsInterleaveMode flag describing which interleave the JPEG-LS datastream should use

static void DJLSEncoderRegistration::cleanup (  )  [static]

deregisters encoders.

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