sublime中为Markdown文档插入剪切板中的图片
sublime中为Markdown文档插入剪切板中的图片的插件没有合适的，找到一个不是很好用，几年前开发的，以及不维护了。于是，自己写一个吧。
插入剪切板中的图片
自己写的好处就是，各种问题都可以自己去进行修复，进行定制化的配置。这个也是的，在Macos系统下面是Retina屏，截屏保存的图片的像素是普通屏幕的大概4倍，就是长度和宽度都变成了2倍。
所以，我在粘贴图片的时候就会在普通的![]() 后面再加上原始截屏时的长度和宽度![](){width="10" height="10"}。这样，即使在Retina屏下截取的图片也不影响，最终呈现的大小和原始的Retina一样，而不是4倍。
目前直接使用全路径，将所有的图片放在一个单独的文件夹，而不是一般的，放在.md文件的当前目录下面，这样，.md文档的目录看起来更干净一些。
由于sublime的默认包里面没有PIL包，所以，使用了外置的python来执行，需要在环境变量中加入python的路径。并且安装PIL包。
清理图片
在粘贴的过程中，有可能会截图多次，或者文章中把图片删除了，但实际上的图片并没有删除。可以把图片对应的文章中的引用扫描一下，如果没有引用了，则可以删除掉。这样，可以把不需要的图片及时清理掉。默认把清理的图片移动到backup目录，可以自己确认之后再删除。
