I am trying to create a pdf from rendered ejs file but cannot render image properly no matter how I try.

my app.js :

let express = require("express");
let app = express();
let ejs = require("ejs");
let pdf = require("html-pdf");
let path = require("path");

app.use( express.static( "public" ) );

app.get("/generateReport", (req, res) => {
    ejs.renderFile("./views/report-template.ejs",  (err, data) => {
    if (err) {
          res.send(err);
    } else {

        pdf.create(data).toFile("certificate.pdf", function (err, data) {
            if (err) {
                res.send(err);
            } else {
                res.send("File created successfully");
            }
        });
    }

    console.log('Server listening on port 3000'); 
  });

this work for me, parameter "base" in options pdf //base: ${req.protocol}://${req.get('host')}

var options = {
                        "format": "A4",
                        "orientation": "portrait",
                         base: `${req.protocol}://${req.get('host')}`,
               };

pdf.create(resulthtml, options).toStream(function(err, stream) {
                        if (err) res.end('An error occurred on create pdf');
                        res.setHeader('Content-disposition', 'inline; filename="' + stream.filename + '"');
                        res.setHeader('Content-type', 'application/pdf');
                        stream.pipe(res);
});

then now in template 

<img src="/public/image.png">

or simply

 <img src="image.png">
