Method Details

averaging

public boolean averaging()

Returns true for any instances of Matrices.ResizingMethod.Averaging class, in particular, for AVERAGING and POLYLINEAR_AVERAGING cases, false for other cases.

Returns:

whether this mode performs averaging of several elements.

interpolation

public final boolean interpolation()

Returns true for POLYLINEAR_INTERPOLATION and POLYLINEAR_AVERAGING cases, and for inheritors of Matrices.ResizingMethod.Averaging class created with Matrices.InterpolationMethod.POLYLINEAR_FUNCTION constructor argument, false for other cases.

Returns:

whether this mode performs some form of interpolation between elements.

interpolationMethod

public final Matrices.InterpolationMethod interpolationMethod()

Returns Matrices.InterpolationMethod.POLYLINEAR_FUNCTION for POLYLINEAR_INTERPOLATION and POLYLINEAR_AVERAGING cases, Matrices.InterpolationMethod.STEP_FUNCTION for SIMPLE and AVERAGING cases, and the argument of the constructor for inheritors of Matrices.ResizingMethod.Averaging class.

Returns:

the interpolation method used while resizing.
