I'm using libGDX for an android game; as far as I can tell, it doesn't have an API for blurring.
Reading on Wikipedia, it seems like blur is formed by setting each pixels RGB values to the average of all adjacent values. Which doesn't seem easily possible in libGDX -- setting pixel data.
So my question is simple:
Is it possible to fake (a decent) blur using only images?
I can potentially overlay multiple (in number, transparency, type) images; but can I create a convincing blur like this?
I'm tempted to say "no," but maybe someone else has achieved something similar. For clarity, I want a set of 1+ generic images I can render on top of ANY image to generate a blur-like effect.
