Canvas Method of Blur isn't working correctly

[Abner Soares Alves Junior]

Your method to generate blured image with canvas is small but not correct.
If you get other libs that already exist to do that you will see that is not correctly.
Lastly if you get an image rendered with canvas method and compare with filter method you will see.

It seems that I have no idea of how to improve it. Can you help me improve the canvas blur algorithm?

For sure on my free time I help with this. 👍
