XcmsCIELabQueryMax(3)		XLIB FUNCTIONS		 XcmsCIELabQueryMax(3)

NAME
       XcmsCIELabQueryMaxC,  XcmsCIELabQueryMaxL,  XcmsCIELabQueryMaxLC,  Xcm-
       sCIELabQueryMinL	- obtain the CIE L*a*b*	coordinates

SYNTAX
       Status XcmsCIELabQueryMaxC(XcmsCCC ccc, XcmsFloat hue_angle,  XcmsFloat
	      L_star, XcmsColor	*color_return);

       Status  XcmsCIELabQueryMaxL(XcmsCCC ccc,	XcmsFloat hue_angle, XcmsFloat
	      chroma, XcmsColor	*color_return);

       Status XcmsCIELabQueryMaxLC(XcmsCCC ccc,	XcmsFloat hue_angle, XcmsColor
	      *color_return);

       Status  XcmsCIELabQueryMinL(XcmsCCC ccc,	XcmsFloat hue_angle, 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 lightness
		 (MaxL)	or minimum lightness (MinL).

       color_return
		 Returns the CIE L*a*b*	coordinates of	maximum	 chroma	 (MaxC
		 and  MaxLC),  maximum	lightness (MaxL), or minimum lightness
		 (MinL)	displayable by the screen for the given	hue angle  and
		 lightness  (MaxC),  hue  angle	and chroma (MaxL and MinL), or
		 hue angle (MaxLC).  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_angle Specifies the hue angle (in degrees) at which to find maximum
		 chroma	(MaxC and MaxLC), maximum lightness (MaxL), or minimum
		 lightness (MinL).

       L_star	 Specifies the lightness (L*) at which to find maximum	chroma
		 (MaxC).

DESCRIPTION
       The  XcmsCIELabQueryMaxC	 function,  given  a  hue angle	and lightness,
       finds the point of maximum chroma displayable by	the  screen.   It  re-
       turns this point	in CIE L*a*b* coordinates.

       The  XcmsCIELabQueryMaxL	 function, given a hue angle and chroma, finds
       the point in CIE	L*a*b* color space  of	maximum	 lightness  (L*)  dis-
       playable	 by  the  screen.  It returns this point in CIE	L*a*b* coordi-
       nates.  An XcmsFailure return value usually indicates  that  the	 given
       chroma is beyond	maximum	for the	given hue angle.

       The  XcmsCIELabQueryMaxLC  function, given a hue	angle, finds the point
       of maximum chroma displayable by	the screen.  It	returns	this point  in
       CIE L*a*b* coordinates.

       The  XcmsCIELabQueryMinL	 function, given a hue angle and chroma, finds
       the point of minimum lightness (L*) displayable by the screen.  It  re-
       turns  this  point  in  CIE  L*a*b* coordinates.	 An XcmsFailure	return
       value usually indicates that the	given chroma is	beyond maximum for the
       given hue angle.
