how to add a small image into a large image

@jcupitt Hi, I have such python code below and I wanna rewrite it with pyvips. What should I do?

import numpy as np

start_point_x, start_point_y = 500, 500

small_one = np.ones((2048, 2448, 3), np.uint8)
s_h, s_w, s_c = small_one.shape
big_one = np.zeros((10000, 10000, 3), np.uint8)

big_one[start_point_y: start_point_y+s_h, start_point_x: start_point_x+s_w, :] = small_one

print(np.sum(big_one), np.sum(small_one))

I found a horrible problem in 2.1.6 – some internal tables could grow exponentially in some cases.

I’ve fixed it, and your code should run quickly now. Thanks!

Thanks very much! version 2.1.7 worked!
