14              chroma, XcmsColor *color_return);
15
16       Status XcmsCIELuvQueryMaxLC(XcmsCCC ccc, XcmsFloat hue_angle, XcmsColor
17              *color_return);
18
19       Status XcmsCIELuvQueryMinL(XcmsCCC ccc, XcmsFloat hue_angle, XcmsFloat
20              chroma, XcmsColor *color_return);

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
30
31       color_return
32                 Returns the CIE L*u*v* coordinates of maximum chroma (MaxC
33                 and MaxLC), maximum lightness (MaxL), or minimum lightness
34                 (MinL) displayable by the screen for the given hue angle and
35                 lightness (MaxC), hue angle and chroma (MaxL and MinL), or
36                 hue angle (MaxLC).  The white point associated with the
37                 returned color specification is the Screen White Point.  The
38                 value returned in the pixel member is undefined.
39
40
41       hue_angle Specifies the hue angle (in degrees) at which to find maximum
42                 chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum
43                 lightness (MinL).
44
45       L_star    Specifies the lightness (L*) at which to find maximum chroma
46                 (MaxC) or maximum lightness (MaxL).

DESCRIPTION

49       The XcmsCIELuvQueryMaxC function, given a hue angle and lightness,
50       finds the point of maximum chroma displayable by the screen.  It
51       returns this point in CIE L*u*v* coordinates.
52
53       The XcmsCIELuvQueryMaxL function, given a hue angle and chroma, finds
54       the point in CIE L*u*v* color space of maximum lightness (L*) dis‐
55       playable by the screen.  It returns this point in CIE L*u*v* coordi‐
56       nates.  An XcmsFailure return value usually indicates that the given
57       chroma is beyond maximum for the given hue angle.
58
59       The XcmsCIELuvQueryMaxLC function, given a hue angle, finds the point
60       of maximum chroma displayable by the screen.  It returns this point in
61       CIE L*u*v* coordinates.
62
63       The XcmsCIELuvQueryMinL function, given a hue angle and chroma, finds
64       the point of minimum lightness (L*) displayable by the screen.  It
65       returns this point in CIE L*u*v* coordinates.  An XcmsFailure return
66       value usually indicates that the given chroma is beyond maximum for the
67       given hue angle.
