XcmsCIELabQueryMax(3X11)  XLIB FUNCTIONS XcmsCIELabQueryMax(3X11)


NAME
       XcmsCIELabQueryMaxC, XcmsCIELabQueryMaxL, XcmsCIELabQuery
       MaxLC, XcmsCIELabQueryMinL - obtain the CIE L*a*b* coordi
       nates

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

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

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

       Status XcmsCIELabQueryMinL(ccc, hue_angle, chroma,
       color_return)
	     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 proce
		 dures 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 lightnes
		 (MaxL), or minimum lightness (MinL) displayable
		 by the screen for the given hue angle and light
		 ness (MaxC), hue angle and chroma (MaxL and
		 MinL), or hue angle (MaxLC).  The white point
		 associated with the returned 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).

XcmsCIELabQueryMax(3X11)  XLIB FUNCTIONS XcmsCIELabQueryMax(3X11)


       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 returns this point in CIE L*a*b* coor
       dinates.

       The XcmsCIELabQueryMaxL function, given a hue angle and
       chroma, finds the point in CIE L*a*b* color space of maxi
       mum lightness (L*) displayable by the screen.  It returns
       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.

       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*) dis
       playable by the screen.	It returns 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.
