| InterpolationNearest | | final public class InterpolationNearest extends Interpolation (Code) | | A class representing nearest-neighbor interpolation. Since
nearest-neighbor interpolation is simply pixel copying, and not
really interpolation at all, most code that performs
nearest-neighbor sampling will want to use special-purpose code.
However, this class is provided both as a way to specify such
interpolation, with the consumer making use of 'instanceof' to
detect the particular class, and as a way to force general
Interpolation users to use nearest-neighbor sampling.
Note that this interpolator does not actually select the
"nearest" pixel, but only uses the truncated integer pixel
location (floor). This is an optimization reflecting an
assumption about the implementation of the resampler. It
is assumed that the conversion of continuous source
image coordinates to discrete pixel indices drops the final
subtraction of 0.5 for the case of a nearest-neighbor interpolator.
Neighborhoods of sizes 2x1, 1x2, 2x2, 4x1, 1x4, 4x4, Nx1 and
1xN, that is, all the interpolate() methods defined in the
Interpolation class, are supported in the interest of simplifying
code that handles a number of types of interpolation. In each
case, the central sample is returned and the rest are ignored.
The class is marked 'final' so that it may be more easily inlined.
