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









                             ‐2‐


          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).

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.
