    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：

    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

def tree_to_dict(tree):
    d = {}

            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

def gen_png_from_plist(plist_filename, png_filename):
    file_path = plist_filename.replace('.plist', '')

        sizelist = [ int(x) for x in to_list(v['sourceSize'])]
        rect_on_big = big_image.crop(box)
        '''
        result_image = Image.new('RGBA', sizelist, (0,0,0,0))
        result_box=(

            ( sizelist[1] - height )/2,

        if not os.path.isdir(file_path):
            os.mkdir(file_path)
        outfile = (file_path+'/' + k).replace('gift_', '')
        print result_box,"-----result_box-"
        print outfile, "generated"
        # result_image.save(outfile)
        '''

        if v['rotated']:
            rect_on_big = rect_on_big.rotate(90)
        if not os.path.isdir(file_path):
            os.mkdir(file_path)
        outfile = (file_path+'/' + k).replace('gift_', '')
        if not outfile.lower().endswith('.png'):   #PIL fails if no extension
            outfile += ".png";
        print "saving:" + outfile;
        rect_on_big.save(outfile);
        print "saved:" + outfile;

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 )
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
