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).

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

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*) 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.

       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.
