Linux系统下的pdf文档可标注阅读工具--PDF Studio Pro

尽管PDF文档格式是公开的，不知为什么，Linux系统中的PDF阅读器总是不令人满意，特别是具有文档标注功能的。更奇怪的是，今天偶然搜到的PDF Studio具有这一功能，但之前搜索可编辑软件时，搜到的网页在比较各种阅读器时都没有提及它。

主页在（），下载后安装也很简单：sh ./PDFStudio_v8_x_x_linux.sh

安装后试了一下，常用的注释工具都有，复杂的自己用不到的没有细看。


在使用上还是稍有不变，比如，删除一个注释，没看到del的功能，尽管可以undo撤销，但undo和删除的含义和方便性是不用多说的。和Win下面的另一个工具PDF-XChange Viewer相比，功能性简单一些，比如颜色的设置，在PDF Studio里面有看到。
