T - A - public class ArrayImg<T extends NativeType<T>,A extends DataAccess> extends AbstractNativeImg<T,A> implements SubIntervalIterable<T>
Img stores an image in a single linear array of basic types. By
that, it provides the fastest possible access to data while limiting the
number of basic types stored to Integer.MAX_VALUE. Keep in mind that
this does not necessarily reflect the number of pixels, because a pixel can
be stored in less than or more than a basic type entry.entitiesPerPixel, linkedType, numEntitiesdimension, max, n, numPixels| Constructor and Description |

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.

RandomAccessibleThe returned random access covers as much of the domain as possible.
Please note:RandomAccessibleIntervals 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.
randomAccess in interface RandomAccessible<T extends NativeType<T>>public ArrayRandomAccess<T> randomAccess(Interval interval)
RandomAccessible
The returned random access is intended to be used in the specified
interval only. Thus, the RandomAccessible may provide optimized versions.
If the interval is completely contained in the domain, the random access
is guaranteed to provide the same values as that obtained by
RandomAccessible.randomAccess() within the interval.

IterableRealIntervalIterableRealInterval. 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 in interface IterableRealInterval<T extends NativeType<T>>iterationOrder in interface RandomAccessibleInterval<T extends NativeType<T>>IterableRealInterval.FlatIterationOrderpublic ArrayImgFactory<T> factory()
ImgImgFactory that creates Imgs of the same kind as
this one.
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 in interface Img<T extends NativeType<T>>public Cursor<T> cursor(Interval interval)
