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 Value	(MaxV).

  _c_o_l_o_r_s__i_n__o_u_t
	    Returns nsamples of	color specifications in	XcmsTekHVC such	that
	    the	Chroma is the maximum attainable for the Value and Hue.	 The
	    white point	associated with	the returned color specification is
	    the	Screen White Point.  The value returned	in the pixel member
	    is undefined.

  _c_o_l_o_r__r_e_t_u_r_n
	    Returns the	maximum	Chroma along with the actual Hue and Value
	    (MaxC), maximum Value along	with the Hue and Chroma	(MaxV),	color
	    specification in XcmsTekHVC	for the	maximum	Chroma,	the Value at
	    which that maximum Chroma is reached and actual Hue	(MaxVC)	or
	    minimum Value and the actual Hue and Chroma	(MinL) at which	the
	    maximum Chroma (MaxC and MaxVC), maximum Value (MaxV), or minimum
	    Value (MinL) was found.  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	    Specifies the Hue in which to find the maximum Chroma (MaxC	and
	    MaxVC), maximum Value (MaxV), the maximum Chroma/Value samples
	    (MaxVSamples), or the minimum Value	(MinL).

  _n_s_a_m_p_l_e_s  Specifies the number of samples.

  _v_a_l_u_e	    Specifies the Value	in which to find the maximum Chroma (MaxC) or
	    minimum Value (MinL).

DESCRIPTION
  The _X_c_m_s_T_e_k_H_V_C_Q_u_e_r_y_M_a_x_C function, given a Hue	and Value, determines the
  maximum Chroma in TekHVC color space displayable by the screen.  Note	that
  it returns the maximum Chroma	along with the actual Hue and Value at which
  the maximum Chroma was found.

  The _X_c_m_s_T_e_k_H_V_C_Q_u_e_r_y_M_a_x_V function, given a Hue	and Chroma, determines the
  maximum Value	in TekHVC color	space displayable by the screen.  Note that
  it returns the maximum Value and the actual Hue and Chroma at	which the
  maximum Value	was found.

  The _X_c_m_s_T_e_k_H_V_C_Q_u_e_r_y_M_a_x_V_C function, given a Hue, determines the maximum
  Chroma in TekHVC color space displayable by the screen and the Value at
  which	that maximum Chroma is reached.	 Note that it returns the maximum
  Chroma, the Value at which that maximum Chroma is reached, and the actual
  Hue for which	the maximum Chroma was found.

  The _X_c_m_s_T_e_k_H_V_C_Q_u_e_r_y_M_a_x_V_S_a_m_p_l_e_s returns nsamples of maximum Value, Chroma at
  which	that maximum Value is reached, and the actual Hue for which the	max-
  imum Chroma was found.  These	sample points may then be used to plot the
  maximum Value/Chroma boundary	of the screen's	color gamut for	the specified
  Hue in TekHVC	color space.

  The _X_c_m_s_T_e_k_H_V_C_Q_u_e_r_y_M_i_n_V function, given a Hue	and Chroma, determines the
  minimum Value	in TekHVC color	space displayable by the screen.  Note that
  it returns the minimum Value and the actual Hue and Chroma at	which the
  minimum Value	was found.
