public class ScriptIntrinsicColorMatrix
extends ScriptIntrinsic

Intrinsic for applying a color matrix to allocations. This has the same effect as loading each element and converting it to a F32_4(RenderScript), multiplying the result by the 4x4 color matrix as performed by rsMatrixMultiply() and writing it to the output after conversion back to U8_4(RenderScript).

Summary

Protected constructors

ScriptIntrinsicColorMatrix(long id, RenderScript rs)

Public methods

static ScriptIntrinsicColorMatrix create(RenderScript rs, Element e)

Create an intrinsic for applying a color matrix to an allocation.

void forEach(Allocation ain, Allocation aout, Script.LaunchOptions opt)

Invoke the kernel and apply the matrix to each cell of input Allocation and copy to the output Allocation.

void forEach(Allocation ain, Allocation aout)

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

Script.KernelID getKernelID()

Get a KernelID for this intrinsic kernel.

void setAdd(Float4 f)

Set the value to be added after the color matrix has been applied.

void setAdd(float r, float g, float b, float a)

Set the value to be added after the color matrix has been applied.

void setColorMatrix(Matrix3f m)

Set the color matrix which will be applied to each cell of the image.

void setColorMatrix(Matrix4f m)

Set the color matrix which will be applied to each cell of the image.

void setGreyscale()

Set a color matrix to convert from RGB to luminance.

void setRGBtoYUV()

Set the matrix to convert from RGB to YUV with a direct copy of the 4th channel.

void setYUVtoRGB()

Set the matrix to convert from YUV to RGB with a direct copy of the 4th channel.

Protected constructors

ScriptIntrinsicColorMatrix

ScriptIntrinsicColorMatrix (long id, 
                RenderScript rs)

Parameters
id long
rs RenderScript

Public methods

create

ScriptIntrinsicColorMatrix create (RenderScript rs, 
                Element e)

Create an intrinsic for applying a color matrix to an allocation. Supported elements types are U8_4(RenderScript)

Parameters
rs RenderScript: The RenderScript context
e Element: Element type for intputs and outputs
Returns
ScriptIntrinsicColorMatrix ScriptIntrinsicColorMatrix

forEach

void forEach (Allocation ain, 
                Allocation aout, 
                Script.LaunchOptions opt)

Invoke the kernel and apply the matrix to each cell of input Allocation and copy to the output Allocation. If the vector size of the input is less than four, the remaining components are treated as zero for the matrix multiply. If the output vector size is less than four, the unused vector components are discarded.

Parameters
ain Allocation: Input allocation
aout Allocation: Output allocation
opt Script.LaunchOptions: LaunchOptions for clipping

forEach

void forEach (Allocation ain, 
                Allocation aout)

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

Parameters
ain Allocation: Input allocation
aout Allocation: Output allocation

getKernelID

Script.KernelID getKernelID ()

Get a KernelID for this intrinsic kernel.

Returns
Script.KernelID Script.KernelID The KernelID object.

setAdd

void setAdd (Float4 f)

Set the value to be added after the color matrix has been applied. The default value is {0, 0, 0, 0}

Parameters
f Float4: The float4 value to be added.

setAdd

void setAdd (float r, 
                float g, 
                float b, 
                float a)

Set the value to be added after the color matrix has been applied. The default value is {0, 0, 0, 0}

Parameters
r float: The red add value.
g float: The green add value.
b float: The blue add value.
a float: The alpha add value.

setColorMatrix

void setColorMatrix (Matrix3f m)

Set the color matrix which will be applied to each cell of the image. This will set the alpha channel to be a copy.

Parameters
m Matrix3f: The 3x3 matrix to set.

setColorMatrix

void setColorMatrix (Matrix4f m)

Set the color matrix which will be applied to each cell of the image.

Parameters
m Matrix4f: The 4x4 matrix to set.

setGreyscale

void setGreyscale ()

Set a color matrix to convert from RGB to luminance. The alpha channel will be a copy.

setRGBtoYUV

void setRGBtoYUV ()

Set the matrix to convert from RGB to YUV with a direct copy of the 4th channel.

setYUVtoRGB

void setYUVtoRGB ()

Set the matrix to convert from YUV to RGB with a direct copy of the 4th channel.
