在给Android游戏或app打包时，经常会遇到有几十上百个渠道的问题。不同的渠道app的名字不一样，icon也可能不一样。程序员总是懒的，最烦手动去改来改去。因此用Python写了一个自动裁剪不同尺寸的icon，并保存到Android对应的icon目录下的脚本。

这里贴下代码，留个脚印。日后直接拷贝使用。(记得安装下pillow第三方库。pip install pillow)

#!/usr/bin/python

# -*- coding:utf-8 -*-

# 此脚本功能：根据一张大的icon自动生成不同尺寸的icon，并保存到对应目录下

import os

from PIL import Image

# 原始icon文件名，必须与脚本同目录下

ORIGIN_ICON_PATH = "icon.png"

# 输出icon的目录和icon文件名

OUTPUT_ICON_PATH = "proj.android/res/drawable-"

OUTPUT_ICON_NAME = "icon"

ICON_SIZE_DICT = {"ldpi": (36, 36), "mdpi": (48, 48), "hdpi": (72, 72), "xhdpi": (96, 96), "xxhdpi": (114, 114)}

def make_more_images():

if not os.path.isfile(ORIGIN_ICON_PATH) and not os.path.exists(ORIGIN_ICON_PATH):

print ORIGIN_ICON_PATH + " is NOT exist."

return

im = Image.open(ORIGIN_ICON_PATH)

print "origin size: " + im.size.__str__()

if im.size[0] != im.size[1]:

print "width and height MUST be same."

return

if im.size[0] < ICON_SIZE_DICT.get("xxhdpi")[0]:

print "image size is TOO small."

return

for dpi, size in ICON_SIZE_DICT.items():

path = OUTPUT_ICON_PATH + dpi

if not os.path.isdir(path):

print "make [" + dpi + ": " + size.__str__() + "] fail. why: "\

+ os.path.basename(path) + " is invalid folder."

continue

path = path + "/" + OUTPUT_ICON_NAME + ".png"

if os.path.isfile(path) and os.path.exists(path):

os.remove(path)

im.resize(size).save(path, "PNG")

print "make [" + dpi + ": " + size.__str__() + "] success."

if __name__ == "__main__":

print '======MAKE ICON START======'

make_more_images()

print '=======MAKE ICON END======='

os.system("pause")
