Syntax

xyz = whitepoint(string)
xyz = whitepoint

Description

xyz = whitepoint(string) returns xyz, a three-element row vector of XYZ values scaled so that Y = 1. string specifies the white reference illuminant. The following table lists all the possible values for string. The default value is enclosed in braces ({}).

'a'	CIE standard illuminant A
'c'	CIE standard illuminant C
'd50'	CIE standard illuminant D50
'd55'	CIE standard illuminant D55
'd65'	CIE standard illuminant D65
{'icc'}	ICC standard profile connection space illuminant; a 16-bit fractional approximation of D50

xyz = whitepoint is the same as xyz = whitepoint('icc').

Class Support

string is a character array. xyz is of class double.

Examples

Return the XYZ color space representation of the default white reference illuminant 'icc'.

wp_icc = whitepoint

wp_icc =

    0.9642    1.0000    0.8249
