Basics
Origin – This property returns the Origin value.
Index2 origVal = extVal.Origin;
//result is an Index2 of 1, 2
Stride – This property returns the increment for each Extent in the Extent2. This is
the constant step between the values.
Index2 incVal = extVal.Stride;
//result is an Index2 of 1, 1
The methods exposed by this class are as follows:
Extent2 extVal = new Extent2(new Index2 (1, 2), new Index2(5, 10));
Clone – This method is an overridden base class method and creates a cloned copy of the
object.
Extent2 clonedVal = (Extent2)extVal.Clone();
Contains - This method checks whether given position is represented by this Extent2.
To be represented, each of the values in the input Index2 must be within its respective
Extent in the Extent2. In the first example, the first Extent in the Extent2 contains
the 1, but the second does not contain the 20 so the result is false. In the second
example, both values (1 & 3) are contained in their respective Extent objects.
bool result = extVal.Contains(new Index2 (1, 20));
//result is false. Second extent doesn’t contain 20
result = extVal.Contains(new Index2 (1, 3));
//result is true. Values are in respective Extentss
ContainsIndex - This method checks whether the given index is valid for this
Extent2. This means that the values provided in the input Index2 are valid indexes into
the array represented by the Extent contained in the Extent2. The first case below is
true because both indexes are valid. The second case is false because 12 is an index
