 ## What Is BlurKit?
 BlurKit is an extraordinarily easy to use and performant utility to render real time blur effects in Android.

 This results in an average work/frame time of 2-4ms, which will be a seamless experience for most users and apps.

-```groovy
-compile 'com.alterac.blurkit:blurkit-core:1.0.0'

 The layout background will continuously blur the content behind it. If you know your background content will be somewhat static, you can set the layout `fps` to `0`. At any time you can re-blur the background content by calling `invalidate()` on the `BlurLayout`.

 Other attributes you can configure are the blur radius and the downscale factor. Getting these to work together well can take some experimentation. The downscale factor is a performance optimization; the bitmap for the background content will be downsized by this factor before being drawn and blurred.
