- Return the data for the tile _c_o_n_t_a_i_n_i_n_g the specified coordinates. The
- data placed in _b_u_f are returned decompressed and, typically, in the
- native byte- and bit-ordering, but are otherwise packed (see further
- below). The buffer must be large enough to hold an entire tile of data.
- Applications should call the routine _T_I_F_F_T_i_l_e_S_i_z_e to find out the size
- (in bytes) of a tile buffer. The _x and _y parameters are always used by
- _T_I_F_F_R_e_a_d_T_i_l_e. The _z parameter is used if the image is deeper than 1
- slice (_I_m_a_g_e_D_e_p_t_h>1). The _s_a_m_p_l_e parameter is used only if 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).

- The library attempts to hide bit- and byte-ordering differences between
- the image and the native machine by converting data to the native machine
- order. Bit reversal is done if the _F_i_l_l_O_r_d_e_r tag is opposite to the
- native machine bit order. 16- and 32-bit samples are automatically
- byte-swapped if the file was written with a byte order opposite to the
- native machine byte order,

- _T_I_F_F_R_e_a_d_T_i_l_e returns -1 if it detects an error; otherwise the number of
- bytes in the decoded tile is returned.

- All error messages are directed to the _T_I_F_F_E_r_r_o_r(3T) routine.
