/*
|
|
* When possible, converts color specified as a full range value in
|
|
* the fromFormat, into an equivalent full range color in the toFormat.
|
|
* When conversion is impossible (e.g. out of gamut color) a color
|
|
* or black in the full range output format is produced. The input
|
|
* color is given as a fractional color in the parameter named color.
|
|
* The produced color is written over the same parameter used to
|
|
* provide the input color.
|
|
*
|
|
* Each graphic format has 3 color components and each of these
|
|
* components has both a full and in gamut range. This function uses
|
|
* a table that provides the full and in gamut ranges of each of the
|
|
* supported graphic formats. The full range is given by members named
|
|
* c[123]Min to c[123]Max, while the in gamut range is given by members
|
|
* named c[123]Low to c[123]High. In most cases the full and in gamut
|
|
* ranges are equivalent. This occurs when the c[123]Min == c[123]Low and
|
|
* c[123]High == c[123]Max.
|
|
*
|
|
* The input and produced colors are both specified as a fractional amount
|
|
* of the full range. The diagram below provides an overview of the
|
|
* conversion process. The main steps are:
|
|
*
|
|
* 1. Produce black if the input color is out of gamut.
|
|
*
|
|
* 2. Convert the in gamut color into the fraction of the fromFromat
|
|
* in gamut range.
|
|
*
|
|
* 3. Convert from the fraction of the in gamut from format range to
|
|
* the fraction of the in gamut to format range. Produce black
|
|
* if an equivalent color does not exists.
|
|
*
|
|
* 4. Covert from the fraction of the in gamut to format to the
|
|
* fraction of the full range to format.
