Trying to use wkhtmltox to turn an HTML file to an image:
./server.js
const express = require('express');
const fs = require('fs');
const wkhtmltox = require('wkhtmltox');
const app = express();
const converter = new wkhtmltox();
app.get('/tagslegend.png', (request, response) => {
response.status(200).type('png');
converter.image(fs.createReadStream('tagslegend.html'), { format: "png" }).pipe(response);
});
var listener = app.listen(process.env.PORT, function () {
console.log('App listening on port ' + listener.address().port);
});
And ./tagslegend.html:
<!doctype html>
<html>
<body>
<dl>
<dt>中文</dt><dd>In mandarin language.</dd>
</dl>
</body>
</html>
I'm expecting back an image of the above HTML, e.g. (how my browser would render it):
Instead I get back this:
How can I render that HTML to a png dynamically with the correct chinese characters and serve it to clients?
