SYNTAX
  Status XcmsCIELuvQueryMaxC(ccc, hue_angle, L_star, color_return)
	XcmsCCC ccc;
	XcmsFloat hue_angle;
	XcmsFloat L_star;
	XcmsColor *color_return;

  Status XcmsCIELuvQueryMaxL(ccc, hue_angle, chroma, color_return)
	XcmsCCC ccc;
	XcmsFloat hue_angle;
	XcmsFloat chroma;
	XcmsColor *color_return;

  Status XcmsCIELuvQueryMaxLC(ccc, hue_angle, color_return)
	XcmsCCC ccc;
	XcmsFloat hue_angle;
	XcmsColor *color_return;

  Status XcmsCIELuvQueryMinL(ccc, hue_angle, chroma, color_return)
	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 lightnes (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 indi-
  cates that the given chroma is beyond maximum for the given hue angle.
