Canvas blur filter?

[CKurdu]

Hi everybody,
HTML based canvas has filter properties and methods. You can find at this link.

I also need blur effect on Canvas element of Qt Quick. Below code doesn't create error also does not work. ctx.b is a Context2d element

    ctx.b.save();
    ctx.b.filter = 'blur(18px)';
    ctx.b.globalCompositeOperation = 'lighten';
    ctx.b.drawImage(canvas.a, 0, 0);
    ctx.b.restore();

It seems Context2D QML doesn't support filters. How can I create a blur effect without the filter?
You can find a full example is here at 178 line in ether.js.

Thanks.

@CKurdu
you even provide a link to the docs and didn't even check if there is a filter property?! o.O

To come to your question, you can create a blur effect on the whole Canvas element.

Actually, I have realized it later, and I tried it but it doesn't give the same view as original javascript one. I think it is related to my code or maybe qt and html5 are using different algorithms. I don't know exactly.

Thank you for your response.
