SYNTAX

     Status XcmsTekHVCQueryMaxC(XcmsCCC ccc, XcmsFloat hue,
          XcmsFloat value, XcmsColor *color_return);

     Status XcmsTekHVCQueryMaxV(XcmsCCC ccc, XcmsFloat hue,
          XcmsFloat chroma, XcmsColor *color_return);

     Status XcmsTekHVCQueryMaxVC(XcmsCCC ccc, XcmsFloat hue,
          XcmsColor *color_return);

     Status XcmsTekHVCQueryMaxVSamples(XcmsCCC ccc, XcmsFloat
          hue, XcmsColor colors_return[], unsigned int nsamples);

     Status XcmsTekHVCQueryMinV(XcmsCCC ccc, XcmsFloat hue,
          XcmsFloat chroma, XcmsColor *color_return);

ARGUMENTS

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

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

     colors_return
               Returns nsamples of color specifications in
               XcmsTekHVC such that the Chroma is the maximum
               attainable for the Value and Hue. The white point
               associated with the returned color specification
               is the Screen White Point. The value returned in
               the pixel member is undefined. maximum Value along
               with the Hue and Chroma (MaxV), color specifica-
               tion in XcmsTekHVC for the maximum Chroma, the
               Value at which that maximum Chroma is reached and
               actual Hue (MaxVC) or minimum Value and the actual
               Hue and Chroma (MinL) minimum Value (MinL)

     color_return
               Returns the maximum Chroma along with the actual
               Hue and Value (MaxC), at which the maximum Chroma
               (MaxC and MaxVC), maximum Value (MaxV), or was
               found. The white point associated with the
               returned color specification is the Screen White
               Point. The value returned in the pixel member is
               undefined. maximum Value (MaxV), the maximum
               Chroma/Value samples (MaxVSamples), or the minimum
               Value (MinL)

     hue       Specifies the Hue in which to find the maximum
               Chroma (MaxC and MaxVC),.

     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 display-
     able 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 display-
     able 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 display-
     able by the screen. It returns the minimum Value and the
     actual Hue and Chroma at which the minimum Value was found.
