HOTSPOT ZOOM RANGES EXAMPLE
Hotspots can optionally include minimum and maximum values that specify the zoom range within
which the Hotspot will be visible. These values are added using 'ZMIN' and 'ZMAX' in the hotspots.xml file. See the
Zoomify Parameter List in the Documentation folder for details.
In this example note that hotspots in the center of the image are visible only when zoomed halfway in, while the hotspot
at the far right is visible only at 100% zoom.
