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 procedures are ignored.

       chroma    Specifies the chroma at which  to  find  maximum  lightness  (MaxL)  or  minimum
                 lightness (MinL).

       color_return
                 Returns  the  CIE L*u*v* coordinates 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.

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

       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*) 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*)  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.
