记一个小软件的开发

喜欢听歌.突然发现酷狗里面的歌手背景图片都还不错.凭印象找到了路径

C:\Users\***\AppData\Roaming\KuGou8\SingerImg(win7)

发现里面有很多内容.关闭kugou.全部删光.再开,点要听的歌,发现文件 ***.kg

试着用N种图片打开方式和格式,都打不开.

发现SingerRes.xml.肯定是这里

在网上找到这个东东

可惜我不喜欢用别人的玩意(特别是没有源码)

用UE打开.kg文件.发现前面几行里面有 jpeg quality=80 这种字符

没看出头绪.再用UE打开2张JPG图片,发现都是以  FF D8 FF E0....这种开头.

再去kg文件里面看到了.于是知道怎么做了.

本来想简单点直接复制二进制出来的.可惜好像行不通.于是只能写代码.

最近在学Python.想试试,去网上找了下Python操作二进制文件.好像很麻烦.

于是先用.net实现,等学到Python文件操作再用Py实现一遍

软件界面

多的不说.上代码
