Basics
Intersection – This method gets the intersection of the given two extent
objects.
Extent2 ext = new Extent2(new Index2 (1, 1), new Index2(2, 3));
//ext is [1 : 1 : 2, 1 : 1 : 3]
Extent2 ext1 = new Extent2(new Index2 (1, 1), new Index2(3, 4));
//ext1 is [1 : 1 : 3, 1 : 1 : 4]
Extent2 ext2 = ext1.Intersection(ext);
//ext2 is [1 : 1 : 2, 1 : 1 : 3]
Reverse – This method returns the reverse of the extent.
Extent2 ext = new Extent2(new Index2 (1, 1), new Index2(2, 3));
//ext is [1 : 1 : 2, 1 : 1 : 3]
Extent2 reverseExt = ext.Reverse();
//reverseExt is [2 : -1 : 1, 3 : -1 : 1]
NearestIndex – This method finds the nearest index in the extent corresponding
to given values in the Index2 input parameter. If the input values are off the end of
the extent, the last index is returned. -1 is returned if the extent is empty. Indexes
into the extent are zero-based.
Extent2 ext = new Extent2(new Index2 (1, 3), new Index2(4, 5));
//ext is [1 : 1 : 4, 3 : 1 : 7]
Index2 nearest = ext.NearestIndex(new Index2(3, 8));
// result is (2, 4)
Here the Extent2 has two arrays {1, 2, 3, 4} and {3, 4, 5, 6, 7}. In the first array,
you are looking for the value 3 and find it at index position 2. In the second array,
you are looking for the value 8, but it is not there. It is beyond the end of the array,
so the index position returned is the last index position or 4. The result is (2, 4).
SnapValue – This method returns the nearest value in each Extent2 that falls on
an extent increment closest to the input values. The returned values can be outside
the range of the Extent2 objects.
Index2 begin = new Index2(3, 5);
Index2 size = new Index2(10, 10);
Index2 inc = new Index2(3, 5);
Extent2 ext = new Extent2(begin, size, inc);
//ext is [3 : 3 : 30, 5 : 5 : 50]
Index2 snap = ext.SnapValue(new Index2(13, 22));
//snap is (12, 10).
In this example, the output Index2 value has elements of 12 and 20. The value 13
falls closest to the value 12 that is an even increment of the starting value of 3 and
