This method works as follows.
Calculates a bounding box around map items contained in specified layers.
Zooms the map to fit the box. Note that the padding factor is applied to the larger dimension of box.
The following image shows an instance when the horizontal dimension larger than the vertical. (“PF” means “Padding Factor” on images)
When the vertical dimension is larger than the horizontal, the zoom appears as follows.
Note that the padding factor is divided by two for each side of the region.
In the instance of the following code
the result should look like the following.
