XcmsCIELuvQueryMaxC(3)						  XLIB FUNCTIONS					    XcmsCIELuvQueryMaxC(3)

NAME

       XcmsCIELuvQueryMaxC, XcmsCIELuvQueryMaxL, XcmsCIELuvQueryMaxLC, XcmsCIELuvQueryMinL - 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, 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) dis-
		 playable 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 mem-
		 ber 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*) dis-
       playable 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.
