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!
http://coastline.freepgs.com/archives/275
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

- 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
