Question

当我尝试将多个图像添加到PDF文件时出现问题。我找不到解决方案，谁可以帮助我...

谢谢！

我的代码！

import './App.css';
import axios from 'axios';
import { useState } from 'react';
import jsPDF from 'jspdf';
import 'jspdf-autotable';

function App() {

  const [products, setProducts] = useState([])

  let doc = new jsPDF()

  function createCatalog() {
    doc.setFontSize(40)
    doc.text(35, 25, 'Paranyan loves jsPDF')
    doc.addImage(`data:image/png;base64, ${products[0].image}`, 'PNG', (1 * 100), 10, 70, 15);
    doc.addImage(`data:image/png;base64, ${products[1].image}`, 'PNG', (2 * 100), 10, 70, 15);
    doc.save('catalogo.pdf')
  }

  async function generateTable() {
    const res = await axios.get('http://localhost:8080');
    let list = [];
    res.data.forEach(item => {
      if(item.codigo) {
        list.push(item)
      }
    })
    setProducts(list);
  }

当我添加相同的图像时，它可以工作！但是当我有2张不同的图片时，它就不起作用了……有不同的方法，它也不起作用。我相信图像不是问题，因为我可以在HTML中显示它们……我也使用过autoTable，它也显示相同的错误。

如何使用JSPDF将多个base64图像添加到pdf文件？
