Methods Summary
public static android.renderscript.ScriptIntrinsicColorMatrix	create(RenderScript rs, Element e) Create an intrinsic for applying a color matrix to an allocation. param rs The RenderScript context param e Element type for inputs and outputs, As of API 19, this parameter is ignored. The Element type check is performed in the kernel launch. deprecated Use the single argument version as Element is now ignored. return ScriptIntrinsicColorMatrix return create(rs);
public static android.renderscript.ScriptIntrinsicColorMatrix	create(RenderScript rs) Create an intrinsic for applying a color matrix to an allocation. param rs The RenderScript context return ScriptIntrinsicColorMatrix long id = rs.nScriptIntrinsicCreate(2, 0); return new ScriptIntrinsicColorMatrix(id, rs);
public void	forEach(Allocation ain, Allocation aout) Invoke the kernel and apply the matrix to each cell of input {@link Allocation} and copy to the output {@link Allocation}. If the vector size of the input is less than four, the remaining components are treated as zero for the matrix multiply. If the output vector size is less than four, the unused vector components are discarded. param ain Input allocation param aout Output allocation forEach(ain, aout, null);
public void	forEach(Allocation ain, Allocation aout, Script.LaunchOptions opt) Invoke the kernel and apply the matrix to each cell of input {@link Allocation} and copy to the output {@link Allocation}. If the vector size of the input is less than four, the remaining components are treated as zero for the matrix multiply. If the output vector size is less than four, the unused vector components are discarded. param ain Input allocation param aout Output allocation param opt LaunchOptions for clipping if (!ain.getElement().isCompatible(Element.U8(mRS)) && !ain.getElement().isCompatible(Element.U8_2(mRS)) && !ain.getElement().isCompatible(Element.U8_3(mRS)) && !ain.getElement().isCompatible(Element.U8_4(mRS)) && !ain.getElement().isCompatible(Element.F32(mRS)) && !ain.getElement().isCompatible(Element.F32_2(mRS)) && !ain.getElement().isCompatible(Element.F32_3(mRS)) && !ain.getElement().isCompatible(Element.F32_4(mRS))) { throw new RSIllegalArgumentException("Unsuported element type."); } if (!aout.getElement().isCompatible(Element.U8(mRS)) && !aout.getElement().isCompatible(Element.U8_2(mRS)) && !aout.getElement().isCompatible(Element.U8_3(mRS)) && !aout.getElement().isCompatible(Element.U8_4(mRS)) && !aout.getElement().isCompatible(Element.F32(mRS)) && !aout.getElement().isCompatible(Element.F32_2(mRS)) && !aout.getElement().isCompatible(Element.F32_3(mRS)) && !aout.getElement().isCompatible(Element.F32_4(mRS))) { throw new RSIllegalArgumentException("Unsuported element type."); } forEach(0, ain, aout, null, opt);
