CMConvertLabToXYZ

Converts colors specified in the L*a*b* color space to the XYZ color space.

pascal CMError CMConvertLabToXYZ (
const CMColor *src, 
const CMXYZColor *white, 
CMColor *dst,
unsigned long count);

src

A pointer to a buffer containing the list of L*a*b* colors to convert to XYZ colors.

white

A pointer to a reference white point.

dst

A pointer to a buffer containing the list of colors as specified in the XYZ color space resulting from the conversion.

count

The number of colors to convert.

function result

A result code of type CMError. See "Result Codes" (page 3-174) for a list of ColorSync-specific result codes.

DISCUSSION

The CMConvertLabToXYZ function converts one or more colors defined in the L*a*b color space to equivalent colors defined in the XYZ color space. Both color spaces are device independent.
