NAME
       XcmsTekHVCQueryMaxC, XcmsTekHVCQueryMaxV, XcmsTekHVCQueryMaxVC, Xcm‐
       sTekHVCQueryMaxVSamples, XcmsTekHVCQueryMinV - obtain the TekHVC coor‐
       dinates

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

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

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

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

       Status XcmsTekHVCQueryMinV(ccc, hue, chroma, color_return)
	     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_in_out
		 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 function, given a Hue and Value, determines the maximum Chroma in
       TekHVC color space displayable by the screen.  Note that it returns the
       maximum Chroma along with the actual Hue and Value at which the maximum
       Chroma was found.

       The function, given a Hue and Chroma, determines the maximum Value in
       TekHVC color space displayable by the screen.  Note that it returns the
       maximum Value and the actual Hue and Chroma at which the maximum Value
       was found.

       The function, given a Hue, determines the maximum Chroma in TekHVC
       color space displayable by the screen and the Value at which that maxi‐
       mum Chroma is reached.  Note that 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 returns nsamples of maximum Value, 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 function, given a Hue and Chroma, determines the minimum Value in
       TekHVC color space displayable by the screen.  Note that it returns the
       minimum Value and the actual Hue and Chroma at which the minimum Value
       was found.
