XcmsCIELuvQueryMaxC(3X11)	XLIB FUNCTIONS	    XcmsCIELuvQueryMaxC(3X11)



NAME
       XcmsCIELuvQueryMaxC, XcmsCIELuvQueryMaxL, XcmsCIELuvQueryMaxLC, Xcm-
       sCIELuvQueryMinL - obtain the CIE L*u*v* coordinates

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, Xcms-
	      Color *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 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*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 associ-
		 ated 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 maxi-
		 mum 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* coordinates.

       The XcmsCIELuvQueryMaxL function, given a hue angle and chroma, finds
       the point in CIE L*u*v* color space of maximum lightness (L*) dis-
       playable by the screen.	It returns this point in CIE L*u*v* coordi-
       nates.  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*) 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.
