Class Overview

Intrinsic for applying a per-channel lookup table. Each channel of the input has an independant lookup table. The tables are 256 entries in size and can cover the full value range of U8_4(RenderScript).

Summary

Public Methods

? Examples 		static ScriptIntrinsicLUT create( RenderScript rs, Element e)
Supported elements types are U8_4(RenderScript) The defaults tables are identity.

? Examples 		void forEach( Allocation ain, Allocation aout)
Invoke the kernel and apply the lookup to each cell of ain and copy to aout.

? Examples 		Script.KernelID getKernelID()
Get a KernelID for this intrinsic kernel.

? Examples 		void setAlpha(int index, int value)
Set an entry in the alpha channel lookup table

? Examples 		void setBlue(int index, int value)
Set an entry in the blue channel lookup table

? Examples 		void setGreen(int index, int value)
Set an entry in the green channel lookup table

? Examples 		void setRed(int index, int value)
Set an entry in the red channel lookup table
