XcmsTekHVCQueryMaxC(3)		 XLIB FUNCTIONS 	  XcmsTekHVCQueryMaxC(3)

NAME
     XcmsTekHVCQueryMaxC, XcmsTekHVCQueryMaxV, XcmsTekHVCQueryMaxVC, XcmsTekHVC-
     QueryMaxVSamples, XcmsTekHVCQueryMinV - obtain the TekHVC coordinates

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 re-
	       turned 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 spec-
     ified 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.
