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.
38
39       color_return
40                 Returns  the  maximum  Chroma  along  with the actual Hue and
41                 Value (MaxC), maximum Value along with  the  Hue  and  Chroma
42                 (MaxV),  color  specification  in  XcmsTekHVC for the maximum
43                 Chroma, the Value at which that maximum Chroma is reached and
44                 actual  Hue  (MaxVC)  or minimum Value and the actual Hue and
45                 Chroma (MinL) at which the maximum Chroma (MaxC  and  MaxVC),
46                 maximum Value (MaxV), or minimum Value (MinL) was found.  The
47                 white point associated with the returned color  specification
48                 is  the  Screen White Point.  The value returned in the pixel
49                 member is undefined.
50
51       hue       Specifies the Hue in which to find the maximum  Chroma  (MaxC
52                 and  MaxVC),  maximum  Value (MaxV), the maximum Chroma/Value
53                 samples (MaxVSamples), or the minimum Value (MinL).
54
55       nsamples  Specifies the number of samples.
56
57       value     Specifies the Value in  which  to  find  the  maximum  Chroma
58                 (MaxC) or minimum Value (MinL).

DESCRIPTION

61       The XcmsTekHVCQueryMaxC function, given a Hue and Value, determines the
62       maximum Chroma in TekHVC color space displayable by the screen.  It re‐
63       turns  the  maximum Chroma along with the actual Hue and Value at which
64       the maximum Chroma was found.
65
66       The XcmsTekHVCQueryMaxV function, given a Hue  and  Chroma,  determines
67       the  maximum Value in TekHVC color space displayable by the screen.  It
68       returns the maximum Value and the actual Hue and Chroma  at  which  the
69       maximum Value was found.
70
71       The  XcmsTekHVCQueryMaxVC function, given a Hue, determines the maximum
72       Chroma in TekHVC color space displayable by the screen and the Value at
73       which  that  maximum Chroma is reached.  It returns the maximum Chroma,
74       the Value at which that maximum Chroma is reached, and the  actual  Hue
75       for which the maximum Chroma was found.
76
77       The  XcmsTekHVCQueryMaxVSamples  returns nsamples of maximum Value, the
78       Chroma at which that maximum Value is reached, and the actual  Hue  for
79       which  the  maximum  Chroma was found.  These sample points may then be
80       used to plot the maximum Value/Chroma boundary of  the  screen's  color
81       gamut for the specified Hue in TekHVC color space.
82
83       The  XcmsTekHVCQueryMinV  function,  given a Hue and Chroma, determines
84       the minimum Value in TekHVC color space displayable by the screen.   It
85       returns  the  minimum  Value and the actual Hue and Chroma at which the
86       minimum Value was found.
