1 2 Android RenderScriptIntrinsic Sample 3 =================================== 4 5 RenderScriptIntrinsic sample that demonstrates how to use RenderScript intrinsics. 6 Creates several RenderScript intrinsics and shows a filtering result with various parameters. 7 Also shows how to extends RedioButton with StateListDrawable. 8 9 Introduction 10 ------------ 11 12 [RenderScript][1] is a framework for running computationally intensive tasks at high performance on Android. RenderScript is 13 primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can 14 benefit as well. 15 16 RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen 17 in image processing. Intrinsics provide extremely high-performance implementations of standard 18 functions with a minimal amount of code. 19 20 This sample shows how to access and use the blur, convolve, and matrix intrinsics: 21 22 ```java 23 mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS)); 24 mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS, 25 Element.U8_4(mRS)); 26 mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS, 27 Element.U8_4(mRS)); 28 ``` 29 30 RenderScript intrinsics will usually be the fastest possible way for a developer to perform these operations. The 31 Android team works closely with our partners to ensure that the intrinsics perform as fast as possible on their 32 architectures 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 36 Pre-requisites 37 -------------- 38 39 - Android SDK 24 40 - Android Build Tools v24.0.1 41 - Android Support Repository 42 43 Screenshots 44 ------------- 45 46 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 47 48 Getting Started 49 --------------- 50 51 This sample uses the Gradle build system.
