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.
