- _r Specifies the region.
-
- _r_1
- _r_2 Specify the two regions.
-
- _w_i_d_t_h
- _h_e_i_g_h_t Specify the width and height, which define the
- rectangle.
-
- _x
- _y Specify the x and y coordinates, which define the
- point or the coordinates of the upper-left corner
- of the rectangle.

- The _X_E_m_p_t_y_R_e_g_i_o_n function returns _T_r_u_e if the region is
- empty.
-
- The _X_E_q_u_a_l_R_e_g_i_o_n function returns _T_r_u_e if the two regions
- have the same offset, size, and shape.
-
- The _X_P_o_i_n_t_I_n_R_e_g_i_o_n function returns _T_r_u_e if the point (x, y)
- is contained in the region r.
-
- The _X_R_e_c_t_I_n_R_e_g_i_o_n function returns _R_e_c_t_a_n_g_l_e_I_n if the
- rectangle is entirely in the specified region, _R_e_c_t_a_n_g_l_e_O_u_t
- if the rectangle is entirely out of the specified region,
- and _R_e_c_t_a_n_g_l_e_P_a_r_t if the rectangle is partially in the
- specified region.
