## Detailed Description

representation parameter for JPEG-LS

## Constructor & Destructor Documentation

## ◆ DJLSRepresentationParameter()

DJLSRepresentationParameter::DJLSRepresentationParameter | ( | Uint16 | nearlosslessDeviation = 2,
|  | OFBool | losslessProcess = OFTrue )

constructor

Parameters

  nearlosslessDeviation | used as parameter NEAR in JPEG-LS nearlossless-encoding process
  losslessProcess | true if lossless process is requested

Referenced by DJLSRepresentationParameter().

## Member Function Documentation

## ◆ className()

virtual const char * DJLSRepresentationParameter::className | ( |  | ) | const
| virtual

returns the class name as string.

can be used in operator== as poor man's RTTI replacement.

Implements DcmRepresentationParameter.

## ◆ clone()

virtual DcmRepresentationParameter * DJLSRepresentationParameter::clone | ( |  | ) | const
| virtual

this methods creates a copy of type DcmRepresentationParameter * it must be overweritten in every subclass.

Returns
  copy of this object

Implements DcmRepresentationParameter.

References DcmRepresentationParameter::DcmRepresentationParameter().

## ◆ getnearlosslessDeviation()

Uint16 DJLSRepresentationParameter::getnearlosslessDeviation | ( |  | ) | const
| inline

returns the desired NEAR parameter

Returns
  return desired NEAR-Parameter

References nearlosslessDeviation_.

## ◆ operator==()

virtual OFBool DJLSRepresentationParameter::operator== | ( | const DcmRepresentationParameter & | arg | ) | const
| virtual

compares an object to another DcmRepresentationParameter.

Implementation must make sure that classes are comparable.

Parameters

  arg | representation parameter to compare with

Returns
  true if equal, false otherwise.

Implements DcmRepresentationParameter.

References DcmRepresentationParameter::DcmRepresentationParameter().

## ◆ useLosslessProcess()

OFBool DJLSRepresentationParameter::useLosslessProcess | ( |  | ) | const
| inline

returns true if lossless compression is desired

Returns
  true if lossless compression is desired

References losslessProcess_.

## Member Data Documentation

## ◆ nearlosslessDeviation_

Uint16 DJLSRepresentationParameter::nearlosslessDeviation_
| private

desired NEAR parameter Default is 0 (lossless compression).

Ignored during lossless compression.
