Use pinch zoom with only pdf.js

[Manmade]

I use pdf.js right now and I wonder if it is possible to get pinch zoom to work somehow with just pdf.js?
Thanks a lot!

I don't think they support that in the example viewer provided, you would have to integrate it yourself.

I am using PDF.js .Now I want to do pinch zoom in PDF.js using the way you have done in TouchPDF.
I added the below code to the pdfcontainer:
$("#viewer").panzoom({
contain: 'invert'
, minScale: 1
, disablePan: true
, increment: 0.25
, maxScale: 2
, onChange: function () {
//linksDisabled = true;
console.log("inside onchange:::::::");
$("#viewer").panzoom("option", "disablePan", false);
//state = ZOOMEDIN;
}
, onEnd: function () {
setTimeout(function () {
console.log("inside onchange end:::::::");
$("#viewer").panzoom( 'zoom', {increment: .01});
//linksDisabled = false;
//if ($drag.panzoom("getMatrix")[0] == 1) zoomReset();
}, 1);
}

        });
        $("#viewer").panzoom('enable');

But still on zoom the pdf page is getting blurry.
Have I missed anything.Would be glad if you may suggest something on it.
Thanks
