Member Function Documentation

determineRepresentation()

static EP_Representation DicomImageClass::determineRepresentation ( double  minvalue, double  maxvalue  )

static

determine integer representation which is necessary to store values in the specified range

Parameters

minvalue	minimum value to be stored
maxvalue	maximum value to be stored

Returns

integer representation (enum)

getRepresentationBits()

static unsigned int DicomImageClass::getRepresentationBits ( EP_Representation  repres )

static

determine number of bits used for a particular integer representation

Parameters

repres

integer representation (enum) to be checked

Returns

number of bits

isRepresentationSigned()

static int DicomImageClass::isRepresentationSigned ( EP_Representation  repres )

static

determine whether integer representation is signed or unsigned

Parameters

repres

integer representation (enum) to be checked

Returns

true if representation is signed, false if unsigned

maxval()

static unsigned long DicomImageClass::maxval ( const int  mv_bits, const unsigned long  mv_pos = 1  )

inlinestatic

calculate maximum value which could be stored in the specified number of bits

Parameters

mv_bits	number of bits
mv_pos	value subtracted from the maximum value (0 or 1)

Returns

maximum value

rangeToBits()

static unsigned int DicomImageClass::rangeToBits ( double  minvalue, double  maxvalue  )

static

calculate number of bits which are necessary to store the specified value range

Parameters

minvalue	minimum value to be stored
maxvalue	maximum value to be stored

Returns

number of bits

tobits()

static unsigned int DicomImageClass::tobits ( unsigned long  tb_value, const unsigned long  tb_pos = 1  )

inlinestatic

calculate number of bits which are necessary to store the specified value

Parameters

tb_value	value to be stored
tb_pos	value subtracted from the value (0 or 1) before converting

Returns

number of bits
