                   dtype=np.uint8)

    img = py_gd.from_array(arr)

    img.save('junk.bmp')

    for y in range(img.height):
        for x in range(img.width):
            assert arr[y, x] == img.get_pixel_value((x, y))

Example #2

def test_array_creation():
    arr = np.array([[0, 1, 2], [3, 4, 5], [6, 7, 8], [9, 10, 11]],
                   dtype=np.uint8,
                   order='c')

    img = py_gd.from_array(arr)
