NAME
       XcmsCIELabQueryMaxC, XcmsCIELabQueryMaxL, XcmsCIELabQueryMaxLC, XcmsCIELabQueryMinL - 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).  or minimum lightness (MinL) or hue
		 angle (MaxLC)

       color_return
		 Returns the CIE L*a*b* 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 associated 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).

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* 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* 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*) 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.
