A zoom hotspot defines a zoomable region on the page. When tapped the region is zoomed in to almost fill the screen and any remaining visible area beyond the hotspot is dimmed.
Hotspot = Zoom
Note: The Zoom hotspot does not work on long scrolling pages, and because of this is not advisable to use it on B (Both) pages.
If you have more than one zoomable region on a page, it is best practice to name each one uniquely by appending a number to the hotspot url, e.g. Zoom1, Zoom2 and so on. This will allow you to use actions on each region individually. See below for more details:
|Hotspot URL||Zoom (optionally numbered Zoom1, Zoom2 etc)|
|Hotspot options||scale=, noclamp (see below for details)|
|Examples||Download example from here|
|scale=<n>||Scaling factor: 1.0 (100%) means zoom to fit entire screen, 0.5 (50%) would be half the screen size, 2.0 (200%) would be twice the screen size. Default is 0.95 i.e. 95%. It is not recommended to go beyond 2.0 due to memory constraints.|
|noclamp||By default the zoomed region will try to display in the centre of the screen. However when it is very close to the screen edge it will be clamped to the edge so may not be able to be fully centred. Use the “noclamp” option to disable clamping and force the zoomed region to display in the centre of the screen. Be aware that this may reveal part of the next page or the background underneath.|

Zoom hotspots can be zoomed via remote action hotspots by sending the “tap” action. This performs the same action as if the user tapped on the zoom hotspot. Actions may also include the zoom options as detailed above.
Action,Zoom1,tap - tell Zoom1 hotspot to zoom in Action,Zoom2,tap - tell Zoom2 hotspot to zoom in Action,Zoom2,tap,scale=0.75 - tell Zoom2 hotspot to zoom in to 75% rather than the default
