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

     Sets the current line width within the cairo context. The line
     width value specifies the diameter of a pen that is circular in
     user space, (though device-space pen may be an ellipse in general
     due to scaling/shear/rotation of the CTM).

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

     cairoSetLineWidth(cr, width)

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

    'cr': ['Cairo']  a 'Cairo'

 'width': [numeric]  a line width

_D_e_t_a_i_l_s:

     Note: When the description above refers to user space and CTM it
     refers to the user space and CTM in effect at the time of the
     stroking operation, not the user space and CTM in effect at the
     time of the call to 'cairoSetLineWidth'. The simplest usage makes
     both of these spaces identical. That is, if there is no change to
     the CTM between a call to 'cairoSetLineWith()' and the stroking
     operation, then one can just pass user-space values to
     'cairoSetLineWidth' and ignore this note.

     As with the other stroke parameters, the current line width is
     examined by 'cairoStroke', 'cairoStrokeExtents', and
     'cairoStrokeToPath()', but does not have any effect during path
     construction.

     The default line width value is 2.0.
