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

Protected constructors

ScriptIntrinsicLUT(long id, RenderScript rs)

Public methods

static ScriptIntrinsicLUT create(RenderScript rs, Element e)

Supported elements types are U8_4(RenderScript) The defaults tables are identity.

void forEach(Allocation ain, Allocation aout)

Invoke the kernel and apply the lookup to each cell of ain and copy to aout.

Script.KernelID getKernelID()

Get a KernelID for this intrinsic kernel.

void setAlpha(int index, int value)

Set an entry in the alpha channel lookup table

void setBlue(int index, int value)

Set an entry in the blue channel lookup table

void setGreen(int index, int value)

Set an entry in the green channel lookup table

void setRed(int index, int value)

Set an entry in the red channel lookup table
