  21.      _T_I_F_F_D_e_f_a_u_l_t_S_t_r_i_p_S_i_z_e returns the number of rows for a reasonable-sized
  22.      strip according to the current settings of the _I_m_a_g_e_W_i_d_t_h, _B_i_t_s_P_e_r_S_a_m_p_l_e,
  23.      _S_a_m_p_l_e_s_P_e_r_P_i_x_e_l, tags and any compression-specific requirements.  If the
  24.      _e_s_t_i_m_a_t_e parameter, if non-zero, then it is taken as an estimate of the
  25.      desired strip size and adjusted according to any compression-specific
  26.      requirements.  The value returned by this function is typically used to
  27.      define the _R_o_w_s_P_e_r_S_t_r_i_p tag.  In lieu of any unusual requirements
  28.      _T_I_F_F_D_e_f_a_u_l_t_S_t_r_i_p_S_i_z_e tries to create strips that have approximately 8
  29.      kilobytes of uncompressed data.
  30.  
  31.      _T_I_F_F_S_t_r_i_p_S_i_z_e returns the equivalent size for a strip of data as it would
  32.      be returned in a call to _T_I_F_F_R_e_a_d_E_n_c_o_d_e_d_S_t_r_i_p or as it would be expected
  33.      in a call to _T_I_F_F_W_r_i_t_e_E_n_c_o_d_e_d_S_t_r_i_p.
  34.  
  35.      _T_I_F_F_V_S_t_r_i_p_S_i_z_e returns the number of bytes in a strip with _n_r_o_w_s rows of
  36.      data.
  37.  
  38.      _T_I_F_F_C_o_m_p_u_t_e_S_t_r_i_p returns the strip that contains the specified
  39.      coordinates.  A valid strip is always returned; out-of-range coordinate
  40.      values are clamped to the bounds of the image.  The _r_o_w parameter is
  41.      always used in calculating a strip.  The _s_a_m_p_l_e parameter is used only if
  42.      data are organized in separate planes (_P_l_a_n_a_r_C_o_n_f_i_g_u_r_a_t_i_o_n=2).
  43.  
  44.      _T_I_F_F_N_u_m_b_e_r_O_f_S_t_r_i_p_s returns the number of strips in the image.
