如何在WP8应用程序上获得模糊的背景

Question

How do we get that awesome blur effect in our apps? I don't think a blurred PNG file is the solution - or is it?

Below is a sample of what I'm talking about. I found it on this page.

Edit: I cannot seem to get SO to upload an image so I will keep trying in the meantime, but you can see the picture I'm referring to via the link above, just scroll down a bit to just above the "prototype" section where it shows pics for the Cocktail app.

Answer 1

I suspect the original app to which you linked used a blurred image (ie the image had a blur effect applied to it already). That seems like the least processor-intensive way to get the effect you want.

On the other hand, if your background is customisable and you still want to apply a blur effect, you could use the Nokia Imaging SDK ( also on Nuget ) to blur any image on the fly. There is some patented technology inside that SDK that helps to keep processor / memory use to a minimum and therefore might make it usable for this kind of background effect.

this link might help you upto some extent but not exactly the focus blur effect which you need.
