XcmsCIELabQueryMax(3)                          XLIB FUNCTIONS                          XcmsCIELabQueryMax(3)



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 pro-cedures procedures
                 cedures 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), max-imum maximum
                 imum 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* coor-dinates. coordinates.
       dinates.  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.
