Arguments
- region1
- An instance of type
<region>. - region2
- An instance of type
<region>.
Values
- region
- An instance of type
<region>.

Description
Returns a region that contains all points that are in either of the regions region1 or region2 (possibly with some points removed in order to satisfy the dimensionality rule)
The result of region-union always has dimensionality that is the maximum dimensionality of region1 and region2. For example, the union of a path and an area produces an area; the union of two paths is a path.
Note: region-union may return either a simple region or a region set.
