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.

       color_return
                 Returns the maximum Chroma along with the actual Hue and Value  (MaxC),  maximum
                 Value  along  with  the Hue and Chroma (MaxV), color specification 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) at
                 which the maximum Chroma (MaxC and MaxVC),  maximum  Value  (MaxV),  or  minimum
                 Value  (MinL)  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.

       hue       Specifies  the Hue in which to find the maximum 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  displayable 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 displayable 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 displayable by the screen.  It returns the minimum Value and the actual
       Hue and Chroma at which the minimum Value was found.
