blobStream is not defined about canvas2pdf HOT 8 CLOSED

This is canvas data what I get.
How can I use canvas2pdf with fabric js canvas ?

from canvas2pdf.

from canvas2pdf.

In new canvas2pdf.PdfContext (blobStream() I passed Only one Parameter but there in canvas2pdf.js there were two parameters
canvas2pdf.PdfContext = function (stream, options) {
if (stream == null) {
throw new Error('Stream must be provided.');
}
var _this = this;
var doc = new PDFDocument(options);
this.stream = doc.pipe(stream);
this.doc = doc;

I dont understand what data passed in options parameter .

my code -
var pdfCanvas: any = document.querySelector('canvas');
var ctx = new canvas2pdf.PdfContext(window.blobStream());
ctx.fillStyle = 'yellow';
ctx.fillRect(100, 100, 100, 100);
pdfCanvas.src = ctx.stream.toBlobURL('application/pdf');

Its throw error
PDFDocument is not defined
i think its throw because of options parameter is undifined

Thank you.

You have to issue drawing commands after creating an instance of canvas2pdf.PdfContext.
