Merging QR Image with Base64 encoded PDF

[umashankarsharma]

Hi ,

I have PDF in base 64 encoded form. I want to edit and add an QR image to it using PDF kit.

Somehow when i try to merge the streams the content fails . Below is the code.

var base64 = require('base64-stream');
var PDFDocument = require('pdfkit');

    var doc = new PDFDocument ();

    doc.image('test.jpeg', {
            fit: [250, 300],
            align: 'center',
            valign: 'center'
    });

    var finalString = ''; // contains the base64 string
    var stream = doc.pipe(base64.encode());
    doc.end();

    var finalString = '';

    stream.on('data', function(chunk) {
            finalString += chunk;});

    stream.on('end', function() {
     // the stream is at its end, so push the resulting base64 string to the response
            read.writeFileSync('./report.pdf', finalString);
     });
