ARGUMENTS

23       ccc       Specifies the CCC.  Note that the CCC's Client White Point
24                 and White Point Adjustment procedures are ignored.
25
26       chroma    Specifies the chroma at which to find maximum lightness
27                 (MaxL) or minimum lightness (MinL).
28
29       color_return
30                 Returns the CIE L*a*b* coordinates of maximum chroma (MaxC
31                 and MaxLC), maximum lightness (MaxL), or minimum lightness
32                 (MinL) displayable by the screen for the given hue angle and
33                 lightness (MaxC), hue angle and chroma (MaxL and MinL), or
34                 hue angle (MaxLC).  The white point associated with the
35                 returned color specification is the Screen White Point.  The
36                 value returned in the pixel member is undefined.
37
38       hue_angle Specifies the hue angle (in degrees) at which to find maximum
39                 chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum
40                 lightness (MinL).
41
42       L_star    Specifies the lightness (L*) at which to find maximum chroma
43                 (MaxC).
44

DESCRIPTION

46       The XcmsCIELabQueryMaxC function, given a hue angle and lightness,
47       finds the point of maximum chroma displayable by the screen.  It
48       returns this point in CIE L*a*b* coordinates.
49
50       The XcmsCIELabQueryMaxL function, given a hue angle and chroma, finds
51       the point in CIE L*a*b* color space of maximum lightness (L*) dis‐
52       playable by the screen.  It returns this point in CIE L*a*b* coordi‐
53       nates.  An XcmsFailure return value usually indicates that the given
54       chroma is beyond maximum for the given hue angle.
55
56       The XcmsCIELabQueryMaxLC function, given a hue angle, finds the point
57       of maximum chroma displayable by the screen.  It returns this point in
58       CIE L*a*b* coordinates.
59
60       The XcmsCIELabQueryMinL function, given a hue angle and chroma, finds
61       the point of minimum lightness (L*) displayable by the screen.  It
62       returns this point in CIE L*a*b* coordinates.  An XcmsFailure return
63       value usually indicates that the given chroma is beyond maximum for the
64       given hue angle.
