阅读英文书箱的小工具

使用场景

Trading System 读书笔记，哈哈，其实就是用来看英文文档用的，为什么要用这款软件呢？因为在Ubuntu上用自带的软件打开pdf后，把内容拷贝下来后，格式是有点混乱的，再放在google translate里面翻译时就会导致不连贯而使结果不准确。

主要有以下几点：

  • 一个句子被隔断了
  • 一个断落该换行时而没被换行
  • 有些字符后面拷贝出来后某名的给你在后面加了空格，导致一个单词一分为二
  • 隔页拷贝的时候，会把页脚和页眉也拷贝进去，关键还是给你夹在句子当中的

使用前提

操作系统：Ubuntu

书箱格式：Pdf

软件：Ubuntu自带阅读软件

如何使用

  1. 提前打开软件。

    ./TranPdfUbuntu.py

  2. 在阅读软件里面把内容拷贝好
  3. 按Ctrl+B。这个操作过后，内容在剪切板里已经格式化好了
  4. 粘贴到google translate里面
