1 2Android RenderScriptIntrinsic Sample 3=================================== 4 5RenderScriptIntrinsic sample that demonstrates how to use RenderScript intrinsics. 6Creates several RenderScript intrinsics and shows a filtering result with various parameters. 7Also shows how to extends RedioButton with StateListDrawable. 8 9Introduction 10------------ 11 12[RenderScript][1] is a framework for running computationally intensive tasks at high performance on Android. RenderScript is 13primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can 14benefit as well. 15 16RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen 17in image processing. Intrinsics provide extremely high-performance implementations of standard 18functions with a minimal amount of code. 19 20This sample shows how to access and use the blur, convolve, and matrix intrinsics: 21 22```java 23mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS)); 24mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS, 25 Element.U8_4(mRS)); 26mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS, 27 Element.U8_4(mRS)); 28``` 29 30RenderScript intrinsics will usually be the fastest possible way for a developer to perform these operations. The 31Android team works closely with our partners to ensure that the intrinsics perform as fast as possible on their 32architectures — often far beyond anything that can be achieved in a general-purpose language. 33 34[1]: http://developer.android.com/guide/topics/renderscript/compute.html 35 36Pre-requisites 37-------------- 38 39- Android SDK 24 40- Android Build Tools v24.0.2 41- Android Support Repository 42 43Screenshots 44------------- 45 46<img src="screenshots/main.png" height="400" alt="Screenshot"/> 47 48Getting Started 49--------------- 50 51This sample uses the Gradle build system.
