XcmsTekHVCQueryMaxC(3)		XLIB FUNCTIONS		XcmsTekHVCQueryMaxC(3)

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

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 re-
       turns  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.
