[python] 分解plist图片

注意: 本文分解方法需要使用python.

分解前准备：

1）安装python及对应版本PIL（笔者安装的是2.7）
2）创建以下脚本，脚本命名为unpack_plist.py
3）将对应的fileName.png和fileName.plist文件放在同一文件夹下

分解方式：

1）在命令行中移动到plist所在路径下
2）执行 python unpack_plist.py fileName

分解后：

在plist同级目录下会生成一个跟plist同名的文件夹，里面是分解之后的碎图

                d[item.text] = tree[index + 1].text  
            elif tree[index + 1].tag == 'true':  
                d[item.text] = True

        print ("make sure you have boith plist and png files in the same directory")

无关分解:
关于print的写法：print outfile, "generated"这种写法貌似在python3以上被弃用了，不兼容，需改为print(outfile, "generated")
