public static android.support.v8.renderscript.ScriptIntrinsicConvolve3x3	create(RenderScript rs, Element e) Supported elements types are {@link Element#U8_4} The default coefficients are. [ 0, 0, 0 ] [ 0, 1, 0 ] [ 0, 0, 0 ] param rs The RenderScript context param e Element type for intputs and outputs return ScriptIntrinsicConvolve3x3 if (rs.isNative) { RenderScriptThunker rst = (RenderScriptThunker) rs; return ScriptIntrinsicConvolve3x3Thunker.create(rs, e); } float f[] = { 0, 0, 0, 0, 1, 0, 0, 0, 0}; if (!e.isCompatible(Element.U8_4(rs))) { throw new RSIllegalArgumentException("Unsuported element type."); } int id = rs.nScriptIntrinsicCreate(1, e.getID(rs)); ScriptIntrinsicConvolve3x3 si = new ScriptIntrinsicConvolve3x3(id, rs); si.setCoefficients(f); return si;
public void	forEach(Allocation aout) Apply the filter to the input and save to the specified allocation. param aout Output allocation. Must match creation element type. forEach(0, null, aout, null);
public Script.FieldID	getFieldID_Input() Get a FieldID for the input field of this intrinsic. return Script.FieldID The FieldID object. return createFieldID(1, null);
public Script.KernelID	getKernelID() Get a KernelID for this intrinsic kernel. return Script.KernelID The KernelID object. return createKernelID(0, 2, null, null);
public void	setCoefficients(float[] v) Set the coefficients for the convolve. The convolve layout is [ 0, 1, 2 ] [ 3, 4, 5 ] [ 6, 7, 8 ] param v The array of coefficients to set FieldPacker fp = new FieldPacker(9*4); for (int ct=0; ct < mValues.length; ct++) { mValues[ct] = v[ct]; fp.addF32(mValues[ct]); } setVar(0, fp);
public void	setInput(Allocation ain) Set the input of the blur. Must match the element type supplied during create. param ain The input allocation. mInput = ain; setVar(1, ain);
