Ive send one of the test files you attached to the project, but still the emulator doesn't render them.
It shows all the bytes it received, but doesn't display the image.

Hi, Iam try to using this library , but I get some error like image below:

Depedency:

NGINX : 1.20.2
PHP : 7.3.33

I changed the kinetic version on index.html because kinetic is no longer available
Change :

    <script src="http://d3lp1msu2r81bx.cloudfront.net/kjs/js/lib/kinetic-v4.4.2.min.js"></script>

To :

<script src="https://cdnjs.cloudflare.com/ajax/libs/kineticjs/5.2.0/kinetic.min.js"></script>

I am currently working on this topic as well and have already created a comprehensive viewer if you are still interested in the topic. I implement it with C# but in times of docker that should be no obstacle anymore :)
