Add one more floating region to this target.
When you define a floating region, you define an inner region and offsets outwards from the inner region in all directions to form an outer region. All the pixels of the outer region will be considered as matched if the pixels of the checkpoint inner region match at least one area in the baseline outer region.
- One or more region objects separated by commas.
- Type: Target
- The value returned is the object that called the method. You can use it to call other methods supported by the object class.
