Probably my searches are unsuccessfully because i'm searching in the wrong way. Could you suggest me some starting point ?

... and if your impression is that this method is too timeconsuming to program, just triangulate your (bounded) polygon and calculate S=sum_i area(T_i)*f(x_i) where T_i is the ith triangle and f(x_i) is the probability density function evaluated at the barycenter of T_i.
Best wishes Torsten.
