ARGUMENTS

27       ccc       Specifies the CCC.  Note that the CCC's Client White Point
28                 and White Point Adjustment procedures are ignored.
29
30       chroma    Specifies the chroma at which to find maximum Value (MaxV).
31
32       colors_return
33                 Returns nsamples of color specifications in XcmsTekHVC such
34                 that the Chroma is the maximum attainable for the Value and
35                 Hue.  The white point associated with the returned color
36                 specification is the Screen White Point.  The value returned
37                 in the pixel member is undefined.

41
42
43
44       color_return
45                 Returns the maximum Chroma along with the actual Hue and
46                 Value (MaxC), maximum Value along with the Hue and Chroma
47                 (MaxV), color specification in XcmsTekHVC for the maximum
48                 Chroma, the Value at which that maximum Chroma is reached and
49                 actual Hue (MaxVC) or minimum Value and the actual Hue and
50                 Chroma (MinL) at which the maximum Chroma (MaxC and MaxVC),
51                 maximum Value (MaxV), or minimum Value (MinL) was found.  The
52                 white point associated with the returned color specification
53                 is the Screen White Point.  The value returned in the pixel
54                 member is undefined.
55
56
57
58       hue       Specifies the Hue in which to find the maximum Chroma (MaxC
59                 and MaxVC), maximum Value (MaxV), the maximum Chroma/Value
60                 samples (MaxVSamples), or the minimum Value (MinL).
61
62       nsamples  Specifies the number of samples.
63
64       value     Specifies the Value in which to find the maximum Chroma
65                 (MaxC) or minimum Value (MinL).

DESCRIPTION

68       The XcmsTekHVCQueryMaxC function, given a Hue and Value, determines the
69       maximum Chroma in TekHVC color space displayable by the screen.  It
70       returns the maximum Chroma along with the actual Hue and Value at which
71       the maximum Chroma was found.
72
73       The XcmsTekHVCQueryMaxV function, given a Hue and Chroma, determines
74       the maximum Value in TekHVC color space displayable by the screen.  It
75       returns the maximum Value and the actual Hue and Chroma at which the
76       maximum Value was found.
77
78       The XcmsTekHVCQueryMaxVC function, given a Hue, determines the maximum
79       Chroma in TekHVC color space displayable by the screen and the Value at
80       which that maximum Chroma is reached.  It returns the maximum Chroma,
81       the Value at which that maximum Chroma is reached, and the actual Hue
82       for which the maximum Chroma was found.
83
84       The XcmsTekHVCQueryMaxVSamples returns nsamples of maximum Value, the
85       Chroma at which that maximum Value is reached, and the actual Hue for
86       which the maximum Chroma was found.  These sample points may then be
87       used to plot the maximum Value/Chroma boundary of the screen's color
88       gamut for the specified Hue in TekHVC color space.
89
90       The XcmsTekHVCQueryMinV function, given a Hue and Chroma, determines
91       the minimum Value in TekHVC color space displayable by the screen.  It
92       returns the minimum Value and the actual Hue and Chroma at which the
93       minimum Value was found.
