#Remarks
This method works as follows.
Calculates a bounding box around map items.
Zooms the map to fit the box. Note that the padding factor is applied to the larger dimension of the box.
The following image shows an instance when the vertical dimension is larger than the horizontal. (“PF” means “Padding Factor” on images)
When the horizontal dimension is larger than the vertical, 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
private void VectorLayer_DataLoaded(object sender, DataLoadedEventArgs e) {
map.ZoomToFit(storage.Items, 0.3);
}
the result should look like the following.
