ARGUMENTS

       ccc       Specifies the CCC.  Note that the CCC's Client
                 White Point and White Point Adjustment proce-
                 dures are ignored.

       chroma    Specifies the chroma at which to find maximum
                 Value (MaxV).

       colors_return
                 Returns nsamples of color specifications in Xcm-
                 sTekHVC such that the Chroma is the maximum
                 attainable for the Value and Hue.  The white
                 point associated with the returned color speci-
                 fication is the Screen White Point.  The value
                 returned in the pixel member is undefined.

       color_return
                 Chroma (MaxC and MaxVC), maximum Value (MaxV),
                 the maximum Chroma/Value samples (MaxVSamples),
                 or the minimum Value (MinL).

       nsamples  Specifies the number of samples.

       value     Specifies the Value in which to find the maximum
                 Chroma (MaxC) or minimum Value (MinL).


DESCRIPTION

       The XcmsTekHVCQueryMaxC function, given a Hue and Value,
       determines the maximum Chroma in TekHVC color space dis-
       playable by the screen.  It returns the maximum Chroma
       along with the actual Hue and Value at which the maximum
       Chroma was found.

       The XcmsTekHVCQueryMaxV function, given a Hue and Chroma,
       determines the maximum Value in TekHVC color space dis-
       playable by the screen.  It returns the maximum Value and
       the actual Hue and Chroma at which the maximum Value was
       found.

       The XcmsTekHVCQueryMaxVC function, given a Hue, determines
       the maximum Chroma in TekHVC color space displayable by
       the screen and the Value at which that maximum Chroma is
       reached.  It returns the maximum Chroma, the Value at
       which that maximum Chroma is reached, and the actual Hue
       for which the maximum Chroma was found.

       The XcmsTekHVCQueryMaxVSamples returns nsamples of maximum
       Value, the Chroma at which that maximum Value is reached,
       and the actual Hue for which the maximum Chroma was found.
       These sample points may then be used to plot the maximum
       Value/Chroma boundary of the screen's color gamut for the
       specified Hue in TekHVC color space.

       The XcmsTekHVCQueryMinV function, given a Hue and Chroma,
       determines the minimum Value in TekHVC color space dis-
       playable by the screen.  It returns the minimum Value and
       the actual Hue and Chroma at which the minimum Value was
       found.
