简单粗暴的翻译英文pdf

news 2025/8/4 14:53:23

背景：看书的时候经常遇到英文pdf，没有合适的翻译软件可以快速翻译全书。这里提供一个解决方案。

Step 1

打开英文pdf
CTRL+A全选文字
CTRL+C复制
打开记事本
CTRL+V复制
保存为data.txt

Step 2

写一个C++脚本

// ToolPdf2Html.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//#include <iostream>
#include <cstring>
#include <vector>
#include <unordered_map>
#include <fstream>
#include <iostream>
#include <sstream>
#include <windows.h>//pdf->txt->html (edge translate)
