public class FloorInterpolator<T> extends Floor<RandomAccess<T>> implements RealRandomAccess<T>
RealRandomAccess
to aRandomAccess
by nearest floor interpolation (i.e., the value is sampled at floor(x)).In ImgLib2, the coordinate of a sample corresponds to the 'center' point of the sample, i.e. the location at which the sample was acquired. This scheme is intuitive in both rasters and irregularly samples data but can trigger confusion when displaying images on a screen with a pixel raster which, in this scheme, spans the range [-0.5,width-0.5]. In the screen-friendly alternative scheme, where sample coordinates reference the top left corner of the pixel rectangle representing a sample the range covered by an image is [0,width], however, coordinate transfer functions other than translation and homogeneous scaling generate different results than in the center-scheme. Rendering an image using
FloorInterpolator
means using the top-left-scheme, rendering it usingNearestNeighborInterpolator
,NLinearInterpolator
, orLanczosInterpolator
means using the center-scheme.- Author:

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 theSampler
points at.
-
copy
public FloorInterpolator<T> copy()
- Specified by:
copy
in interfaceSampler<T>
- Returns:
- - A new
Sampler
in the same state accessing the same values. It does NOT copy T, just the state of theSampler
. 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 anArrayCursor
for example)
