SECURITY_ERR: DOM Exception 18 about heatcanvas

[sunng87]

Thank you for using HeatCanvas.

I believe the problem is due to some security restriction of Chrome on local file system. This is a common issue and you can find a SO thread here about it.

I've copied http://sunng87.github.com/heatcanvas/leaflet.html demo to my localhost and changes scripts path to:

<script type="text/javascript" src="http://sunng87.github.com/heatcanvas/heatcanvas.js"></script>
<script type="text/javascript" src="http://sunng87.github.com/heatcanvas/heatcanvas-leaflet.js"></script>

And still get SECURITY_ERR: DOM Exception 18 error. Everything is fine after copying headcanvas scripts to localhost.

Looks like it is an error because of same origin policy for web workers.

Is it possible to somehow 'inline' web-worker code into other headcanvas scripts?

I'm afraid there's no way to inlinize web worker. Please download these scripts and put them on your web path.

And I will write a component.json for bower to make it easies to install.
