Method Detail

numDimensions
public int numDimensions()
Description copied from interface:EuclideanSpace
Gets the space's number of dimensions.- Specified by:
numDimensions
in interfaceEuclideanSpace
-
toString
public java.lang.String toString()
- Overrides:
toString
in classjava.lang.Object
-
getSource
public RandomAccessible<T> getSource()
Description copied from interface:TransformedRandomAccessible
Get the source of the TransformedRandomAccessible. This is the next element in the view hierarchy, for example, the next ExtendedRandomAccessibleInterval or the underlying Img.- Specified by:
getSource
in interfaceTransformedRandomAccessible<T>
- Returns:
- the source
RandomAccessible
.
-
getTransformToSource
public MixedTransform getTransformToSource()
Description copied from interface:TransformedRandomAccessible
Get the transformation from view coordinates intosource
coordinates.Note that this is the inverse of the ''view transform'' which maps source to view coordinates.
- Specified by:
getTransformToSource
in interfaceTransformedRandomAccessible<T>
- Returns:
- transformation from view coordinates into
source
coordinates.
-
randomAccess
public RandomAccess<T> randomAccess(Interval interval)
Description copied from interface:RandomAccessible
Create a random access sampler for integer coordinates.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.- Specified by:
randomAccess
in interfaceRandomAccessible<T>
- Parameters:
interval
- in which interval you intend to use the random access.- Returns:
- random access sampler
-
randomAccess
public RandomAccess<T> randomAccess()
Description copied from interface:RandomAccessible
Create a random access sampler for integer coordinates.The returned random access covers as much of the domain as possible.
Please note:RandomAccessibleInterval
s have a finite domain (theirInterval
), soRandomAccessible.randomAccess()
is only guaranteed to cover this finite domain. This may lead to unexpected results when usingViews
. In the following codeRandomAccessible<T> extended = Views.extendBorder( img ) RandomAccessibleInterval<T> cropped = Views.interval( extended, img ); RandomAccess<T> a1 = extended.randomAccess(); RandomAccess<T> a2 = cropped.randomAccess();
Theaccess
a1
on the extended image is valid everywhere. However, somewhat counter-intuitively, theaccess
a2
on the extended and cropped image is only valid on the intervalimg
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 theRandomAccessibleInterval
, and you know that theRandomAccessibleInterval
is actually defined beyond its interval boundaries, then use theRandomAccessible.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.- Specified by:
randomAccess
in interfaceRandomAccessible<T>
- Returns:
- random access sampler
