## 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 )
| inline static

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 )
| inline static

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
