Public methods

create

ScriptIntrinsicConvolve3x3 create (RenderScript rs, 
                Element e)

Supported elements types are U8(RenderScript), U8_2(RenderScript), U8_3(RenderScript), U8_4(RenderScript), F32(RenderScript), F32_2(RenderScript), F32_3(RenderScript), and F32_4(RenderScript).

The default coefficients are:

[ 0, 0, 0 ]

[ 0, 1, 0 ]

[ 0, 0, 0 ]

Parameters
rs RenderScript: The RenderScript context
e Element: Element type for intputs and outputs
Returns
ScriptIntrinsicConvolve3x3 ScriptIntrinsicConvolve3x3

forEach

void forEach (Allocation aout, 
                Script.LaunchOptions opt)

Apply the filter to the input and save to the specified allocation.

Parameters
aout Allocation: Output allocation. Must match creation element type.
opt Script.LaunchOptions: LaunchOptions for clipping

forEach

void forEach (Allocation aout)

Apply the filter to the input and save to the specified allocation.

Parameters
aout Allocation: Output allocation. Must match creation element type.

getFieldID_Input

Script.FieldID getFieldID_Input ()

Get a FieldID for the input field of this intrinsic.

Returns
Script.FieldID Script.FieldID The FieldID object.

getKernelID

Script.KernelID getKernelID ()

Get a KernelID for this intrinsic kernel.

Returns
Script.KernelID Script.KernelID The KernelID object.

setCoefficients

void setCoefficients (float[] v)

Set the coefficients for the convolve.

The convolve layout is:

[ 0, 1, 2 ]

[ 3, 4, 5 ]

[ 6, 7, 8 ]

Parameters
v float: The array of coefficients to set

setInput

void setInput (Allocation ain)

Set the input of the 3x3 convolve. Must match the element type supplied during create.

Parameters
ain Allocation: The input allocation.
