Hi everyone,

I would like to use the function points_in_poly to test if the point x,y is in the contour cont2
x=0 y=0, but I have the problem with any value of x and y:

skimage.measure.points_in_poly(np.array([x,y]),cont2)  where cont2 is a contour of type  array :
but I get the following error:  "IndexError: invalid index"

it is a little obscure for me, is there a problem with this function, or is it me who don't know how to apply it ?

thanks a lot!

Julien
