python - 在python中生成具有透明像素而不是白色的图像

Question

我有一小段 python 代码，它生成具有随机配色方案的 24x24 像素头像。最初代码中只有 RGB 颜色，但是，我想要一个透明的背景，所以我为所有颜色添加了 alpha 值。因为我只希望背景“bg”是透明的，所以这是唯一一个 alpha 值为 0 的变量。

问题是当我运行代码时，所有保存的图像都是空白的。以下是完整代码：

# Built with python 3, dependencies installed with pip 
# library to generate images - Pillow 
# https://pillow.readthedocs.io/en/stable/installation.html
from PIL import Image

# library to work with arrays 
# https://numpy.org/
import numpy as np

# library to interact with the operating system
import os

# library to generate random integer values
from random import seed
from random import randint

# gets path to be used in image creation mechanism, using os
dirname = os.path.dirname(__file__)

# sets final image dimensions as 480x480 pixels
# the original 24x24 pixel image will be expanded to these 
dimensions
dimensions = 480, 480

# tells how many times to iterate through the following 
mechanism
# which equals the number of birds
# e.g. 
# for x in range(0-200) 
# would generate 201 birds numbered 0-200
for x in range(0, 50):

# using ETH block number as starting random number seed
b=11981207
seed(x+b)

#head color - randomly generate each number in an RGB color
hd = (randint(0, 256), randint(0, 256), randint(0, 256), 1)
c=randint(0,500)
seed(c)

#throat color - same as head color
th = (randint(0, 256), randint(0, 256), randint(0, 256), 1)
d = randint(0,1000)
seed(d)

#eye "white" color
# if random number between 1-1000 is 47 or less - Crazy Eyes!
if d > 47:
    # normal eyes are always the same color
    ew = (240,248,255,1)
    ey = (0, 0, 0, 1)
else:
    # crazy eyes have the same (154, 0, 0) pupil and a random 'eye white' color
    ew = (randint(0, 256), randint(0, 256), randint(0, 256), 1)
    ey = (154, 0, 0, 1)
e = randint(0,1000)
seed(e)

# beak color
f = randint(0, 1000)
if f > 500:
    # if random number is 501-1000 >> grey beak
    bk = (152, 152, 152, 1)
elif 500 >= f > 47:
    # 48-500 >> gold beak
    bk = (204, 172, 0, 1)
elif 47 >= f > 7:
    # 8 >> 47 >> red beak
    bk = (204, 0, 0, 1) 
else:
    # random number is 7 or less >> black beak
    bk = (0, 0, 0, 1) 

# background color
bg = (255, 255, 255, 0)
# outline color
ol = (0, 0, 0, 1)
