PDF编辑网页应用

我将设计一个功能完善的PDF编辑网页应用，支持查看、注释、添加文本和绘制等功能。

设计思路
左侧为PDF缩略图导航
中间为PDF主视图区域
右侧为编辑工具栏
顶部为操作菜单栏
使用PDF.js库实现PDF渲染
使用Fabric.js实现绘图功能

下面是完整的实现代码：

html
<!DOCTYPE html
<html lang=zh-CN
<head
<meta charset=UTF-8
<meta name=viewport content=width=device-width, initial-scale=1.0
<titlePDF编辑器专业PDF编辑工具</title

<script src=https://cdnjs.cloudflare.com/ajax/libs/fabric.js/5.3.1/fabric.min.js</script
