	)			`[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

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.
