Blur for Canvas


Recommended Posts

I've not encountered anything native on canvas that will allow you to do this.

Does it have to be a true Gaussian blur? I can't claim to know the mathematics behind it, but I do know it's expensive to compute, and would involve manipulating the canvas data on a pixel-by-pixel level - likely too slow for real-time game use.

Depending on the scenario, you might be able to fake it. Is there any way you could use Photoshop (or similar) to pre-render any of the blur, and just use canvas to composite the blurred sprites at runtime?
