    public static ScriptIntrinsicColorMatrix create(RenderScript rs,
                                    Element e)

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

    Parameters:

    rs - The Renderscript context

    e - Element type for intputs and outputs

    Returns:

    ScriptIntrinsicColorMatrix

  • setColorMatrix

    public void setColorMatrix(Matrix4f m)

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

    Parameters:

    m - The 4x4 matrix to set.

  • setColorMatrix

    public 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 - The 3x3 matrix to set.

  • setGreyscale

    public void setGreyscale()

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

  • setYUVtoRGB

    public void setYUVtoRGB()

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

  • setRGBtoYUV

    public void setRGBtoYUV()

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

  • forEach

    public void forEach(Allocation ain,
               Allocation aout)

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

    Parameters:

    ain - Input allocation

    aout - Output allocation

  • getKernelID

    public Script.KernelID getKernelID()

    Get a KernelID for this intrinsic kernel.

    Returns:

    Script.KernelID The KernelID object.
