XcmsCIELabQueryMaxC(3X11)
X11R6
NAME
  XcmsCIELabQueryMaxC, XcmsCIELabQueryMaxL, XcmsCIELabQueryMaxLC,
  XcmsCIELabQueryMinL - obtain the CIE L*a*b* coordinates

SYNOPSIS
  Status XcmsCIELabQueryMaxC(ccc, hue_angle, L_star, color_return)
	  XcmsCCC ccc;
	  XcmsFloat hue_angle;
	  XcmsFloat L_star;
	  XcmsColor *color_return;

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

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

  Status XcmsCIELabQueryMinL(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). or minimum lightness (MinL) or hue angle
      (MaxLC)

  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.
