如何从plist文件中提取png图像？
如何从plist文件中提取png图像？
提问于 2011-05-22 07:21:51
我现在有一组plist文件。里面是png图像，有些文件有很多图像。我用的是win64 vista。
我专门为这类产品寻找了一些东西，比如FileJuicer，但这只适用于mac用户。

我编写了这个脚本来解压缩由png打包的plist文件中的TexturePacker文件。
首先，确保png和plist文件位于同一个目录中，在我的示例中是: freeGifts.plist和freeGifts.png。
第二，以下脚本与unpack_plist.py相同
然后，python unpack_plist.py freeGifts将生成大量png文件到名为freeGifts的目录中。
需求: python，PIL

哈哈，这都是史蒂夫·乔布斯在做的。您可以在C#中使用ChadBurggraf的库https://github.com/ChadBurggraf/plists-cs解析plist。但是正如注释中所讨论的，您想要的文件可能不在plist文件中。

感谢Sean.Z。
对于unpack_plist.py，您需要：
1: PIL已安装在您的电脑上。
2:使用python 2.5
python2.5 unpack_plist.py birdfly
否则你会失败的。

对于一些旋转的褶皱，上面的文字可能有一些错误。我将其修改如下：
