SYNOPSIS

       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

       Specifies the CCC. Note that the CCC's Client White Point and White Point Adjustment procedures are ignored.  Specifies the chroma at which
       to find maximum lightness (MaxL) or minimum lightness (MinL). or minimum lightness (MinL) or hue angle (MaxLC) Returns the CIE L*a*b* coor-
       dinates	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  returned
       color  specification  is the Screen White Point. The value returned in the pixel member is undefined.  Specifies the hue angle (in degrees)
       at which to find maximum chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum lightness (MinL).  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.
