outside the range of the second Extent in the Extent2. The valid index range for this
Extent is 0 through 9.
Basics
bool result = extVal.ContainsIndex(new Index2 (0, 1));
//result is true
result = extVal.ContainsIndex(new Index2 (1, 12));
//result is false
CopyIncreasing – This method copies this Extent2 and reverses the values if needed
to ensure a positive increment.
Index2 begin = new Index2(0, 1);
Index2 size = new Index2(5, 5);
Index2 inc = new Index2(-1, 1);
Extent2 ext = new Extent2(begin, size, inc);
//result Extent2 is [0:-1:-4, 1:1:5]
Extent2 newExt = ext.CopyIncreasing();
//newExt = [-4:1:0, 1:1:5]
CreateIncreasing - This method creates an extent that has a positive increment value.
The input values will be reverted to ensure that the new extent has a positive increment.
Index2 begin = new Index2(0, 1);
Index2 end = new Index2(5, 5);
Index2 inc = new Index2(-1, 1);
Extent2 ext = Extent2.CreateIncreasing(begin, end, inc);
//ext = [-4 : 1 : 0, 1 : 1 : 5]
