Subject: Re: polygon intersection routine in IDL
Hi, dear mati,
I tested your function by 2 samples. One returned the overlap polygon
thank you in advance.
shape1 = fltarr(2,4)
shape2[0,0] = 0.5
shape3 = shape_overlap (shape1, shape2, exists = exs)
shape1 = fltarr(2,17)
shape2 = fltarr(2,6)
xrange = [116.06185 ,116.72748]
plot, shape1[0,*], shape1[1,*], xrange = xrange , yrange = yrange
shape3= shape_overlap (shape1, shape2, exists = exs)
