我正在尝试创建一个生成二进制RGB图像的脚本，所有像素必须为black（0,0,0）或white（255,255,255）。问题在于，当脚本保存输出时，某些像素将具有不同黑白阴影的随机值，例如（14,14,14），（18,18,18），（241,241,241）。

#Code generated sample:
from PIL import Image
sample = Image.new('RGB', (2,2), color = (255,255,255)) 
#A four pixel image that will do just fine to this example
pixels = sample.load()
w, h = sample.size #width, height
str_pixels = ""

for i in range(w): #lines
    for j in range(h): #columns

        from random import randint
        rand_bool = randint(0,1)
        if rand_bool:
            pixels[i,j] = (0,0,0)

        str_pixels += str(pixels[i,j]) 
#This will be printed later as single block for readability

print("Code generated sample:") #The block above …
