Android RenderScriptIntrinsic Sample
|
||
|
|
===================================
|
||
|
|
|
||
|
|
RenderScriptIntrinsic sample that demonstrates how to use RenderScript intrinsics.
|
||
|
|
Creates several RenderScript intrinsics and shows a filtering result with various parameters.
|
||
|
|
Also shows how to extends RedioButton with StateListDrawable.
|
||
|
|
|
||
|
|
Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
[RenderScript][1] is a framework for running computationally intensive tasks at high performance on
|
||
|
|
Android. RenderScript is primarily oriented for use with data-parallel computation, although serial
|
||
|
|
computationally intensive workloads can benefit as well.
|
||
|
|
|
||
|
|
RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen
|
||
|
|
in image processing. Intrinsics provide extremely high-performance implementations of standard
|
||
|
|
functions with a minimal amount of code.
|
||
|
|
|
||
|
|
This sample shows how to access and use the blur, convolve, and matrix intrinsics:
|
||
|
|
|
||
|
|
```java
|
||
|
|
mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS));
|
||
|
|
mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS,
|
||
|
|
Element.U8_4(mRS));
|
||
|
|
mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS,
|
||
|
|
Element.U8_4(mRS));
|
||
|
|
```
|
||
|
|
|
||
|
|
RenderScript intrinsics will usually be the fastest possible way for a developer to perform these
|
||
|
|
operations. The Android team works closely with our partners to ensure that the intrinsics perform
|
||
|
|
as fast as possible on their architectures — often far beyond anything that can be achieved in a
|
||
|
|
general-purpose language.
