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 13 Android. RenderScript is primarily oriented for use with data-parallel computation, although serial 14 computationally intensive workloads can 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 31 operations. The Android team works closely with our partners to ensure that the intrinsics perform 32 as fast as possible on their architectures often far beyond anything that can be achieved in a 33 general-purpose language. 34 35 [1]: http://developer.android.com/guide/topics/renderscript/compute.html 36 37 Pre-requisites 38 -------------- 39 40 - Android SDK 28 41 - Android Build Tools v28.0.3 42 - Android Support Repository 43 44 Screenshots 45 ------------- 46 47 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 48 49 Getting Started 50 --------------- 51 52 This sample uses the Gradle build system.
