Method Detail

get

public T get()

Description copied from class: AbstractNLinearInterpolator

Get the interpolated value at the current position.

To visit the pixels that contribute to an interpolated value, we move in a (binary-reflected) Gray code pattern, such that only one dimension of the target position is modified per move.

See http://en.wikipedia.org/ wiki/Gray_code

get in class AbstractNLinearInterpolator<T extends NumericType<T>>

copy

public NLinearInterpolator<T> copy()

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)
