This sample demonstrates using RenderScript to perform basic image manipulation. Specifically, it allows users
|
|
to dynamically adjust the saturation for an image using a slider. A custom RenderScript kernel performs the saturation
|
|
adjustment, running the computation on the device\'s GPU or other compute hardware as deemed appropriate by the system.

[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.
|
|
|
|
The RenderScript runtime will parallelize work across all processors available on a device, such as multi-core CPUs,
|
|
GPUs, or DSPs, allowing you to focus on expressing algorithms rather than scheduling work or load balancing.
|
|
RenderScript is especially useful for applications performing image processing, computational photography, or computer
|
|
vision.
|
|
|
|
This sample demonstrates the fundamentals of writing a RenderScript compute kernel, and using it to perform basic image
|
|
manipulation. In this case, each pixel is transformed based on a liner interpolation between its original
|
|
RGB value and it's luminance (black-and-white) value, weighted based on the user's specified saturation target.
