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

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.

getnearlosslessDeviation()

Uint16 DJLSRepresentationParameter::getnearlosslessDeviation ( ) const

inline

returns the desired NEAR parameter

Returns

return desired NEAR-Parameter

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.

useLosslessProcess()

OFBool DJLSRepresentationParameter::useLosslessProcess ( ) const

inline

returns true if lossless compression is desired

Returns

true if lossless compression is desired

Member Data Documentation

nearlosslessDeviation_

Uint16 DJLSRepresentationParameter::nearlosslessDeviation_

private

desired NEAR parameter Default is 0 (lossless compression).

Ignored during lossless compression.
