Basics
IsSubset – This method returns true if the input Extent2 is a subset of this
Extent2.
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]
bool result = ext1.IsSubset(ext);
//result is true
result = ext.IsSubset(ext1);
//result is false
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
