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).
or minimum lightness (MinL) or hue angle (MaxLC)
_c_o_l_o_r___r_e_t_u_r_n Returns the CIE L*a*b* coordinates of maximum chroma (MaxC and MaxLC), maximum lightness (MaxL),
displayable by the screen for the given hue angle and lightness (MaxC), hue angle and chroma (MaxL and MinL), . The white point associated with the returned color specification is the Screen White Point. The value returned in the pixel member is undefined. or minimum lightness (MinL)
_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), .
_L___s_t_a_r Specifies the lightness (L*) at which to find maximum chroma (MaxC).

DESCRIPTION

The _X_c_m_s_C_I_E_L_a_b_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. It returns this point in CIE L*a*b* coordinates.

The _X_c_m_s_C_I_E_L_a_b_Q_u_e_r_y_M_a_x_L 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 _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_a_b_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. It returns this point in CIE L*a*b* coordinates.

The _X_c_m_s_C_I_E_L_a_b_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. It returns this point in CIE L*a*b* 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.
