-
_c_o_l_o_r

DESCRIPTION
The
_X_c_m_s_S_e_t_W_h_i_t_e_P_o_i_n_t
function changes the Client White Point in the specified CCC.
Note that the pixel member is ignored
and that the color specification is left unchanged upon return.
The format for the new white point must be
_X_c_m_s_C_I_E_X_Y_Z_F_o_r_m_a_t,
_X_c_m_s_C_I_E_u_v_Y_F_o_r_m_a_t,
_X_c_m_s_C_I_E_x_y_Y_F_o_r_m_a_t,
or
_X_c_m_s_U_n_d_e_f_i_n_e_d_F_o_r_m_a_t.
If the color argument is NULL, this function sets the format component of the
Client White Point specification to
_X_c_m_s_U_n_d_e_f_i_n_e_d_F_o_r_m_a_t,
indicating that the Client White Point is assumed to be the same as the
Screen White Point.
This function returns nonzero status
if the format for the new white point is valid;
otherwise, it returns zero.
The
_X_c_m_s_S_e_t_W_h_i_t_e_A_d_j_u_s_t_P_r_o_c
function first sets the white point adjustment procedure and client data
in the specified CCC with the newly specified procedure and client data
and then returns the old procedure.
