markdown图片转换demo
一直以来都是用Markdown来写博客的,但是它的图片嵌入实在是太让人头秃,逼得我能找网上的图片就不用自己的,实在是麻烦。所以我在发现了一个可以生成markdown样式的图床后就写了一个小程序,花了2个小时左右。平常把编辑器文件夹的图片(一般是截图)上传上去,再把markdown形式的链接保存到文件里,然后进行转换。当然有很多限制,比如没有图形化界面(过一阵闲下来就去学Qt),软件必须依赖一个配置文件;没有调用图床的API而是每次需要手动上传(因为白嫖的图床,感觉不太好);需要先把要修改的文档拷贝到配置文件设定的txt文件中(还是因为不会Qt,终端里面输入我觉得太反人类了),然后生成到另一个txt文件中。之后学会Qt、找到了正规图床之后可能会改改吧。

配置文件长这个样子:
输入文档的地址:E://textNeedChange.txt
输出文档的地址:E://textChanged.txt
输出图片的地址:E://afterChangePicture.txt
