包路径：net.imglib2.view.Views
类名称：Views
方法名：offsetInterval
[英]Define an interval on a RandomAccessible and translate it such that the min corner is at the origin. It is the callers responsibility to ensure that the source RandomAccessible is defined in the specified interval.
[中]在随机曲线上定义一个间隔，并对其进行平移，使最小角位于原点。调用者有责任确保在指定的时间间隔内定义源。
