[worldKit-dev] switch between 2 or more sets of zoomify files

[Mikel Maron]

Hi Iain

Sorry for the delay in response, just have a lot going on here.

There is a new Javascript variable to request the current extent of worldkit. That can be downloaded from
http://worldkit.org/download/latest/worldkit.swf


document.worldkit.SetVariable("JGetExtentComm","callbackFunction");

will call your javascript function, "callbackFunction", with the extent and the zoom of the current view. 
Within "callbackFunction", you can set the position of the other worldkit instance, and toggle visibility.

Best,
Mikel

Thanks Mikel,

Got this working well using javascript to toggle the visibility of two
worldkit instances. What Id like now, is a means to fetch the most recent
zoom and location values so that when the user toggles the view, they
maintain their position/zoom (currently when the user toggles to the
alternate view, the new view is fully zoomed-out and centred).

I can see how zoom, lat and long values can be set using the JzoomComm,
but how can these values be fetched without resorting to annotation mode
techniques?

Cheers,

Iain
