_D_e_s_c_r_i_p_t_i_o_n:

     Initialized 'matrix' to a transformation that rotates by
     'radians'.

_U_s_a_g_e:

     cairoMatrixInitRotate(radians)

_A_r_g_u_m_e_n_t_s:

'radians': [numeric]  angle of rotation, in radians. The direction of
          rotation is defined such that positive angles rotate in the
          direction from the positive X axis toward the positive Y
          axis. With the default axis orientation of cairo, positive
          angles rotate in a clockwise direction.

_V_a_l_u_e:

     A list containing the following elements: 

'matrix': ['CairoMatrix']  a 'CairoMatrix'

_A_u_t_h_o_r(_s):

     Derived by RGtkGen from GTK+ documentation
