Public Methods

public static ScriptIntrinsicConvolve3x3 create (RenderScript rs, Element e)

Supported elements types are U8_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.
