problem with negatives coordinates

[jsb72]

hello

thanks for your library

i'm facing a problem when i try to use negatives coordinates

        shape = (0,0)
        scale = 20
        octaves = 3
        lacunarity = 1.0
        persistence = 1.0

        for y in range (-100,shape[1],1):

            for x in range(-100,shape[0],1):

                value = noise.pnoise2(x/scale,y/scale,octaves=octaves,persistence=persistence,lacunarity=lacunarity,repeatx=shape[0],repeaty=shape[1],base=0)

the noise become simple and repeatful

instead of, positives coord :

is there a good way to use negative coord ?

i guess it is because repeatx=shape[0],repeaty=shape[1] is equivalent to repeatx=0,repeaty=0 in this case
and i feel it is the problem ? Not the only one ?
