ARGUMENTS

  _c_c_c	    Specifies the CCC.	Note that the CCC's Client White Point and
	    White Point	Adjustment procedures are ignored.

  _c_h_r_o_m_a    Specifies the chroma at which to find maximum lightness (MaxL) or
	    minimum lightness (MinL).

  _c_o_l_o_r__r_e_t_u_r_n
	    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.

  _h_u_e__a_n_g_l_e Specifies the hue angle in degrees at which	to find	maximum
	    chroma (MaxC and MaxLC), maximum lightness (MaxL), or minimum
	    lightness (MinL).

  _L__s_t_a_r    Specifies the lightness (L*) at which to find maximum chroma
	    (MaxC) or maximum lightness	(MaxL).

DESCRIPTION
  The _X_c_m_s_C_I_E_L_u_v_Q_u_e_r_y_M_a_x_C function, given a hue	angle and lightness, finds
  the point of maximum chroma displayable by the screen.  Note that it
  returns this point in	CIE L*u*v* coordinates.


  The _X_c_m_s_C_I_E_L_u_v_Q_u_e_r_y_M_a_x_L 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.  Note that it returns this point in CIE L*u*v* coordinates.  An
  _X_c_m_s_F_a_i_l_u_r_e return value usually indicates that the given chroma is beyond
  maximum for the given	hue angle.

  The _X_c_m_s_C_I_E_L_u_v_Q_u_e_r_y_M_a_x_L_C function, given a hue angle,	finds the point	of
  maximum chroma displayable by	the screen.  Note that it returns this point
  in CIE L*u*v*	coordinates.

  The _X_c_m_s_C_I_E_L_u_v_Q_u_e_r_y_M_i_n_L function, given a hue	angle and chroma, finds	the
  point	of minimum lightness (L*) displayable by the screen.  Note that	it
  returns this point in	CIE L*u*v* coordinates.	 An _X_c_m_s_F_a_i_l_u_r_e	return value
  usually indicates that the given chroma is beyond maximum for	the given hue
  angle.
