Hi there,

Thanks for your great product, I am using it to embed whiteboard to our site and it is working great.

There is a small problem, in the online drawing page (https://sketchpad.pro/B25E53E0B13653F667F:z6y9x2pn), I see an upload image feature and it is working fine on this page:

But in demo advanced page (https://developers.sketchpad.pro/advanced.html), the upload feature seems only work on json file and do not accept images/pdf files.

I took a look at the source code and here are what I found on demos/js/advanced.js:

Can you please tell me how to edit these lines so I can upload the images/pdf files to the whiteboard (working the same way with online drawing page).

Thanks.

I have small problem when using library - i mean, gulp works perfectly, but then due to some tools error (cannot find and null pointers when accessing them) the sketchpad is never initialized - and this only happenes with the version from git.
Tried to used the sketchpad.js file from the website and it worked - but its much different than the version built by gulp form this git archive. Is there anyway to make the git version actual or get some information about commercial version of spetchpad?

Text input is making the grid move.

clearSketchpad() doesn't affect other users.

Text input clarity is reducing when it draws on canvs at a noticable level.!

How can we move single objects rather than viewport..like i just want to move image or text rather than whole viewport

I found it.

document.getElementById('Clean').addEventListener("click", function () {
        sketchpad.clearSketchpad();
    });
