public class PlanarImg<T extends NativeType<T>,A extends ArrayDataAccess<A>> extends AbstractNativeImg<T,A> implements PlanarAccess<A>, SubIntervalIterable<T>
NativeImg
that stores data in an list of primitive arrays, one per
image plane.
The PlanarImg
provides access to the underlying data arrays via the
getPlane(int)
method.

IterableRealInterval
Returns a RealCursor
that iterates with optimal speed without
calculating the location at each iteration step. Localization is
performed on demand.
Use this where localization is required rarely/ not for each iteration.

public PlanarRandomAccess<T> randomAccess()
RandomAccessible
The returned random access covers as much of the domain as possible.
Please note:RandomAccessibleInterval
s have a finite domain (their Interval
),
so RandomAccessible.randomAccess()
is only guaranteed to cover this finite domain.
This may lead to unexpected results when using Views
. In
the following code
RandomAccessible<T> extended = Views.extendBorder( img ) RandomAccessibleInterval<T> cropped = Views.interval( extended, img ); RandomAccess<T> a1 = extended.randomAccess(); RandomAccess<T> a2 = cropped.randomAccess();The
access
a1
on the extended image is valid
everywhere. However, somewhat counter-intuitively, the
access
a2
on the extended and cropped image
is only valid on the interval img
to which the extended image was
cropped. The access is only required to cover this interval, because it
is the domain of the cropped image. Views
attempts to provide the
fastest possible access that meets this requirement, and will therefore
strip the extension.
To deal with this, if you know that you need to access pixels outside the
domain of the RandomAccessibleInterval
, and you know that the
RandomAccessibleInterval
is actually defined beyond its interval
boundaries, then use the RandomAccessible.randomAccess(Interval)
variant and
specify which interval you actually want to access. In the above example,
RandomAccess<T> a2 = cropped.randomAccess( Intervals.expand( img, 10 ) );will provide the extended access as expected.

IterableRealInterval
IterableRealInterval
. If the
returned object equals (Object.equals(Object)
) the iteration
order of another IterableRealInterval
f then they can be
copied by synchronous iteration. That is, having an Iterator
on
this and another Iterator
on f, moving both in synchrony
will point both of them to corresponding locations in their source
domain. In other words, this and f have the same iteration order
and means and the same number of elements.iterationOrder

This is useful to create Imgs for temporary storage in generic methods
where the specific Img type is unknown. Note, that the factory can be
used even if all references to this Img have been invalidated.factory
