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.
RenderScript 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:
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.
