## ◆ createPaletteColorImage()

static OFCondition DcmQuant::createPaletteColorImage | ( | DicomImage & | sourceImage,
|  | DcmItem & | target,
|  | OFBool | writeAsOW,
|  | OFBool | write16BitEntries,
|  | OFBool | floydSteinberg,
|  | Uint32 | numberOfColors,
|  | OFString & | description,
|  | DcmLargestDimensionType | largeType = DcmLargestDimensionType_default,
|  | DcmRepresentativeColorType | repType = DcmRepresentativeColorType_default )
| static

converts the given color image into a palette color image.

All frames of the image are converted. The converted result is written as a complete Image Pixel module to the given target item.

Parameters

  sourceImage | DICOM color image
  target | target item to which the palette color image is written
  writeAsOW | if true, the LUT Data attributes are encoded as OW instead US. LUT Data is always written as OW if numberOfColors is 65536.
  write16BitEntries | if true, LUT data is encoded with 16 bits per entry
  floydSteinberg | determines whether or not to use Floyd-Steinberg error diffusion during creation of the palette color image
  numberOfColors | desired number of colors in the color palette. Valid range is [2..65536].
  description | description string suitable for use as Derivation Description returned in this parameter
  largeType | algorithm used for determining the largest dimension in the Median Cut algorithm
  repType | algorithm for choosing a representative color for each box in the Median Cut algorithm

Returns
  EC_Normal if successful, an error code otherwise.

References DcmLargestDimensionType_default, and DcmRepresentativeColorType_default.

## ◆ updateDerivationDescription()

static OFCondition DcmQuant::updateDerivationDescription | ( | DcmItem * | dataset,
|  | const char * | description )
| static

create Derivation Description.

If a derivation description already exists, the old text is appended to the new text.

Parameters

  dataset | dataset to be modified
  description | description string.

Returns
  EC_Normal if successful, an error code otherwise
