      • LanczosInterpolator

        public LanczosInterpolator​(RandomAccessible<T> randomAccessible,
                                   int alpha,
                                   boolean clip,
                                   double min,
                                   double max)
        Creates a new Lanczos-interpolation
        Parameters:
        randomAccessible - - the RandomAccessible to work on
        alpha - - the radius of values to incorporate (typically 2 or 3)
        clip - - clips the value to range of the RealType, i.e. tests if the interpolated value is out of range
        min - - range for clipping (ignored if min==max)
        max - - range for clipping (ignored if min==max)
    • Method Detail

      • resetKernel

        protected final void resetKernel()
      • accumulate

        protected final void accumulate​(int d)
      • get

        public T get()
        Description copied from interface: Sampler
        Access the actual T instance providing access to a pixel, sub-pixel or integral region value the Sampler points at.
        Specified by:
        get in interface Sampler<T extends RealType<T>>
      • copy

        public Sampler<T> copy()
        Specified by:
        copy in interface Sampler<T extends RealType<T>>
        Returns:
        - A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)
