 1 | AndroidGaussianBlur
 2 | ===================
 3 | 
 4 | Android Gaussian Blur use RenderScript demo
 5 | 
 6 | Info
 7 | ======
 8 | 1. The idea from App [Blurone -创作毛玻璃效果壁纸][1].
 9 | 2. You just learn [RenderScript][2] to complete the App.
10 | 3. If you want to support Android `2.2+`, please look 
11 | [RenderScript in the Android Support Library][3].
12 | 4. Download the support library and source, use `Android SDK Manager` download Android SDK Build-tools `18.1.0`.
13 | 5. Do `Gaussian Blur`, can use [ScriptIntrinsicBlur][4], and you also want to learn this [page][5].
14 | 6. If you look `RenderScript` source, some advanced below.
15 |   * [GCC and Clang Vector Extensions][6]
