3*d353a188SXin Li===================================
4*d353a188SXin Li
5*d353a188SXin LiRenderScriptIntrinsic sample that demonstrates how to use RenderScript intrinsics.
6*d353a188SXin LiCreates several RenderScript intrinsics and shows a filtering result with various parameters.
7*d353a188SXin LiAlso shows how to extends RedioButton with StateListDrawable.

9*d353a188SXin LiIntroduction
10*d353a188SXin Li------------
11*d353a188SXin Li
12*d353a188SXin Li[RenderScript][1] is a framework for running computationally intensive tasks at high performance on
13*d353a188SXin LiAndroid. RenderScript is primarily oriented for use with data-parallel computation, although serial
14*d353a188SXin Licomputationally intensive workloads can benefit as well.
15*d353a188SXin Li
16*d353a188SXin LiRenderScript **intrinsics** are built-in functions that perform well-defined operations often seen
17*d353a188SXin Liin image processing. Intrinsics provide extremely high-performance implementations of standard
18*d353a188SXin Lifunctions with a minimal amount of code.
19*d353a188SXin Li
20*d353a188SXin LiThis sample shows how to access and use the blur, convolve, and matrix intrinsics:
21*d353a188SXin Li
22*d353a188SXin Li```java
23*d353a188SXin LimScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS));
24*d353a188SXin LimScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS,
25*d353a188SXin Li        Element.U8_4(mRS));
26*d353a188SXin LimScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS,
27*d353a188SXin Li        Element.U8_4(mRS));
28*d353a188SXin Li```
29*d353a188SXin Li
30*d353a188SXin LiRenderScript intrinsics will usually be the fastest possible way for a developer to perform these
31*d353a188SXin Lioperations. The Android team works closely with our partners to ensure that the intrinsics perform
32*d353a188SXin Lias fast as possible on their architectures — often far beyond anything that can be achieved in a
33*d353a188SXin Ligeneral-purpose language.
