当我运行此代码时,我得到输出:

TypeError: an integer is required

我不知道为什么会这样,因为我将这两种数据类型分别设置为 uint8 和 uint64。显然我不太了解数据类型。

from PIL import Image

from numpy import random

N = 100

##open an image
im=Image.open('/Users/grahamwarner/Desktop/Experiment/gwarner/labeled_photos/masks/003030.png')

##create a random image
rand_matrix = random.randint(0, 255, (500, 500, 3)).astype('uint8')

rand_image = Image.fromarray(rand_matrix)

##select N random pixels
rand_pix = random.randint(0,499, (N,2)).astype('uint64')

##replace the random values at these pixels with the original values
for ii in range(N):

  rand_image.putpixel(tuple(rand_pix[ii,:]), im.getpixel(tuple(rand_pix[ii,:])))

PIL 中的getpixel方法似乎对其输入非常挑剔,特别想要一个ints 的元组(与 Numpy 的uint64类型不同)。以下对我有用:

for ii in range(N):
    coordinate = tuple(map(int, rand_pix[ii,:]))
    rand_image.putpixel(coordinate, im.getpixel(coordinate))
