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

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

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

       Status XcmsCIELuvQueryMinL(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).
		 or minimum lightness (MinL) or hue angle (MaxLC)

       color_return
		 Returns the CIE L*u*v* coordinates of maximum
		 chroma (MaxC and MaxLC), maximum lightnes
		 (MaxL), displayable by the screen for the given
		 hue angle and lightness (MaxC), hue angle and
		 chroma (MaxL and MinL),.  The white point asso
		 ciated with the returned color specification is
		 the Screen White Point.  The value returned in
		 the pixel member is undefined.	 or minimum
		 lightness (MinL)

       hue_angle Specifies the hue angle (in degrees) at which to
		 find maximum chroma (MaxC and MaxLC), maximum
		 lightness (MaxL),.

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

DESCRIPTION
       The XcmsCIELuvQueryMaxC function, given a hue angle and
       lightness, finds the point of maximum chroma displayable
       by the screen.  It returns this point in CIE L*u*v* coor
       dinates.

       The XcmsCIELuvQueryMaxL function, given a hue angle and
       chroma, finds the point in CIE L*u*v* color space of maxi
       mum lightness (L*) displayable by the screen.  It returns
       this point in CIE L*u*v* coordinates.  An XcmsFailure
       return value usually indicates that the given chroma is
       beyond maximum for the given hue angle.

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

       The XcmsCIELuvQueryMinL 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*u*v* coordinates.  An XcmsFailure return value usually
       indicates that the given chroma is beyond maximum for the
       given hue angle.
