首先安裝所使用的庫 pillow，

pillow 是用來取代 PIL 的，

pip3 install pillow

安裝成功圖：

簡單的代碼：

from __future__ import print_function

import os, sys

from PIL import Image

imgNames = [((57,57),"icon.png"),

((114,114),"icon@2x.png"),

((171,171),"icon@3x.png"),

((20,20),"icon-20.png"),

((40,40),"icon-20@2x.png"),

((60,60),"icon-20@3x.png"),

((29,29),"icon-29.png"),

((58,58),"icon-29@2x.png"),

((87,87),"icon-29@3x.png"),

((40,40),"icon-40.png"),

((80,80),"icon-40@2x.png"),

((120,120),"icon-40@3x.png"),

((50,50),"icon-50.png"),

((60,60),"icon-60.png"),

((120,120),"icon-60@2x.png"),

((180,180),"icon-60@3x.png"),

((76,76),"icon-76.png"),

((152,152),"icon-76@2x.png"),

((228,228),"icon-76@3x.png"),

((83.5,83.5),"icon-83_5.png"),

((167,167),"icon-83_5@2x.png"),

((250.5,250.5),"icon-83_5@3x.png")]

i = 0

for i in range(len(imgNames)):

imt = Image.open("image.png")

size = imgNames[i][0]

#print size

name = imgNames[i][1]

#print name+type(name)

imt.thumbnail(size)

imt.save(name)

i = i+1

該腳本和圖片（image.png）處于同一目錄下，運行即可。

PS:

當圖片的大小比要生成的圖片大小要小的話，只會按圖片的大小生成出來。
