stitch(To combine a series of elements into an individual, larger one, such as a series of photos into one panoramic photo); unite(To combine two or more shapes or paths to result in a single compound path that represents all of the area that was covered by the individual shapes and paths. If the resulting path is not a solid shape (for example, if there are holes), you can release the compound path, which results in a path object being created for each contiguous edge)
