RealRandomAccess
to a RandomAccess
by nearest neighbor
interpolation.
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
using NearestNeighborInterpolator
, NLinearInterpolator
, or
LanczosInterpolator
means using the center-scheme.

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
- 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)
