这篇博客介绍了三种方法来拆分合图，包括通过cocoscreator和cocosstudio的插件工具，以及利用Python的PIL模块手动拆分。重点讲述了使用Python的方法，详细解释了安装PIL、读取plist文件和图片、解析数据并拆分图片的步骤，适合对编程有一定基础的读者进行图像处理。

1.使用cocos creator的可以到官方商店找对应的插件工具，不过不是免费的... :( ，链接地址：cocos creator合图拆分

2.使用cocos studio就简单一些，直接新建工程导入plist文件，进入文件所在文件夹，看到一个隐藏文件夹，进入里面就是想要的东西了。参考链接：cocos studio合图拆分

3.就是使用python的PIL图片处理模块来拆分了：

（1）安装python，这个自行百度吧，方法简单。

（2）安装python的PIL模块：

pip install Pillow

（3）代码部分：

split.py

#!python  
import os,sys  
from xml.etree import ElementTree  
from PIL import Image  
  
def tree_to_dict(tree):  
    d = {}  
    for index, item in enumerate(tree):  
        if item.tag == 'key':  
            if tree[index+1].tag == 'string':  
                d[item.text] = tree[index + 1].text  
            elif tree[index + 1].tag == 'true':  
                d[item.text] = True  
            elif tree[index + 1].tag == 'false':  
                d[item.text] = False  
            elif tree[index+1].tag == 'dict':  
                d[item.text] = tree_to_dict(tree[index+1])  
    return d
