Public Methods

public static 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 The RenderScript context
e Element type for intputs and outputs
Returns
  • ScriptIntrinsicConvolve3x3

public void forEach ( Allocation aout)

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

Parameters
aout Output allocation. Must match creation element type.

public Script.FieldID getFieldID_Input ()

Get a FieldID for the input field of this intrinsic.

Returns
  • Script.FieldID The FieldID object.

public Script.KernelID getKernelID ()

Get a KernelID for this intrinsic kernel.

[ 6, 7, 8 ]

Parameters
v The array of coefficients to set

public void setInput ( Allocation ain)

Set the input of the blur. Must match the element type supplied during create.

Parameters
ain The input allocation.
