cocos2dx 游戏plist与png完美切成小图python代码

　　首先需要一份python的切图程序：

 #python2.5 unpack_plist.py birdfly 

 #! /usr/lical/bin/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

 if __name__ == '__main__':
     filename = sys.argv[1]
     plist_filename = filename + '.plist'
     png_filename = filename + '.png'
 if (os.path.exists(plist_filename) and os.path.exists(png_filename)):
     gen_png_from_plist( plist_filename, png_filename )

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

Mac 电脑下可以新建一个文本把程序复制进去，保存后缀名为 .py 并移至与需要切的plist与png文件夹下。
