 [IterableInterval](http://javadoc.scijava.org/ImgLib2/net/imglib2/IterableInterval.html) represents an iterable collection of samples at integer coordinates. You can obtain a `Cursor` using the `cursor()` or `localizingCursor()` methods. You can obtain the number of elements using `size()`. The first element can be obtained by `firstElement()` which is a short-cut for `cursor().next()`.
 
-[RandomAccessibleInterval](http://javadoc.scijava.org/ImgLib2/net/imglib2/RandomAccessibleInterval.html) and [IterableInterval](http://javadoc.scijava.org/ImgLib2/net/imglib2/IterableInterval.html) represent bounded images where all samples lie within an interval. Both extend [Interval](http://javadoc.scijava.org/ImgLib2/net/imglib2/Interval.html) which defines methods to obtain the minimum, maximum, and dimensions of the interval. Dimensions refers to the extend of the interval in every dimension, and is defined as `maximum - minimum + 1. You can obtain the maximum and minimum in a single or all dimensions. If you obtain it in all dimensions, it can be stored into a `long[]` array or a `Positionable`. (Have a look at the [Interval](http://javadoc.scijava.org/ImgLib2/net/imglib2/Interval.html) API doc.)
