命令行： python unpack_plist.py plist文件名称

例子： python unpack_plist.py common ## plist文件全名为 common.plist

windows7 下相关python配置：

1. 安装python2.7.3

2. 在此处下载安装（这是最简洁的方式，已经编译好png，zip等处理）

　昨天写了Zwoptex生成精灵表，有合就有分，能不能把合成的文件再原模原样的还原回来，哈哈……于是，今天利用闲暇的时间想一个问题:plist是用xml格式的，强大的python中的PIL（Python Imaging Library）可以处理各种图片，更不用说png图片了。
　　昨天分析过plist，除了一个名字外，今天还能用上的还有两个属性，原始的文件的尺寸大小（这必须得要）和纹理在精灵表中的位置和大小，因为对xml的操作不太多，只是读取数据，就选用轻量级的ElementTree，把从xml解析出来的字符串数据转换成int类型，这就得到了图片属性的真实数据，这在精灵表上复制那个区域内的图片，然后在粘贴到新建的图片里面，哈哈，这样就搞定了。
　　在操作的时候会用到PIL库，点击下载PIL。
　　大概的思路是说出来啦，最实在的还是把代码粘贴出来，运行一下看看：

#encoding=utf-8
import os,Image,sys
from xml.etree import ElementTree
filenames=os.listdir(os.getcwd())
i=0
if len(sys.argv)==2:
    filepath=sys.argv[1]
    for filename in filenames:
        if (filename==filepath+'.png') or (filename==filepath+'.plist'):
            i +=1
    if i==0:
        print("No such file or directory!")
    elif i==1:
        print("Both .png and .plist are need!")
    else:
        treeroot=ElementTree.parse(filepath+'.plist').getroot()
        #p=list(per.iter("key"))
        image=Image.open(filepath+'.png')  #open image
        sizelist=(0,0)
 
        #box=(0,0,0,0)
 
        for dict1 in treeroot:
            for index1,item1 in enumerate(dict1): #
        #        print (item1.tag,item1.attrib,item1.text)
                if item1.text=='frames':  #get node who Value=frames 
        #            print (index1)
                    i=0
                    dict2 = dict1[index1+1]
        #            print(len(dict2))
        #            for index2,item2 in enumerate(dict2):
        #                print(item2.tag,item2.attrib,item2.text)
                    while i<len(dict2):
                        print("name:"+dict2[i].text)
                        picname=dict2[i].text
                        dict3 = dict2[i+1]
                        for index3,item3 in enumerate(dict3):
        #                    print(item3.tag,item3.attrib,item3.text)
                            if item3.text=='spriteSourceSize':
        #                        print(dict3[index3+1].text)
                                size=dict3[index3+1].text
                                sizelist = size.replace('{','').replace('}','').split(',')
                                sizelist=(int(sizelist[0]),int(sizelist[1]));
                                #print(sizelist)
                                 
                            if item3.text=='textureRect':
        #                        print(dict3[index3+1].text)
                                rect=dict3[index3+1].text
                                rectlist = rect.replace('{','').replace('}','').split(',')
        #                        print(rectlist)
                                box=(int(rectlist[0]),int(rectlist[1]),int(rectlist[0])+int(rectlist[2]),int(rectlist[1])+int(rectlist[3]))
                                print("size:")
                                print(sizelist)
                                print("onBig:")
                                print(box)
                                xim=image.crop(box)
                                xxim=Image.new('RGB',sizelist,(255,255,255))
                                box1=((sizelist[0]-box[2]+box[0])/2,(sizelist[1]-box[3]+box[1])/2,(sizelist[0]+box[2]-box[0])/2,(sizelist[1]+box[3]-box[1])/2)
                                print("onNew:")
                                print(box1)
                                xxim.paste(xim,box1,mask=0)
                                if os.path.isdir(filepath):
                                    pass
                                else:
                                    os.mkdir(filepath)
                                outfile=filepath+'/'+picname
                                print("newPath:"+outfile)
                                xxim.save(outfile)
                        i +=2
else:
    print("Please enter only one parameter!")

里面的print比较多，因为怕出错了不好找，就写几步，print出来看看数据对不对。
　　复制这段代码，保存，然后在终端写：python xx.py file(就是想分割的文件名，不加后缀)。
　　本人运行环境：Mac OSＸ10.7,python 2.7.3,PIL 1.1.7,完美通过！

参考网址1：http://blog.afantree.com/python/python2-split-plist-spritesheet.html

结果：~~doesn’t work on python 2.7，报错~~ ==>~~作者已经修正该问题，有兴趣的朋友可以进入以上链接尝试他的方案。~~ ==>该文的方案适用于由Zwoptex制作的png+plist，有兴趣的朋友请移步。

参考网址2：http://stackoverflow.com/a/17838628

结果：不够完善，兼容性不好，于是我又经过了一点修改后，终于在python 2.7下成功。如果你的大图是pvr，需要先用Texture Packer转成png。

下面记录一下步骤：

安装PIL（Python Imaging Library）
附上Mac上自己编译安装PIL的步骤：
1.在xcode中安装命令行工具，如果你尚未安装过的话
2.curl -O -L http://effbot.org/media/downloads/Imaging-1.1.7.tar.gz
3.tar -xzf Imaging-1.1.7.tar.gz
4.cd Imaging-1.1.7
5.python setup.py build
6.sudo python setup.py install

保存以下内容至split_png_plist.py

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

将该py文件和你的xxx.png、xxx.plist放在同一目录下，终端中运行：
python split_png_plist.py xxx
一切顺利的话，当前目录下会生成名为xxx的目录，里面就是分割出来的各png小图
