[ka-Map-users] initialize to a certain position

[Paul Spencer]

Herman,

I don't have easy access to IE to test ka-map on a daily basis, so it  
is likely that some stuff is a bit broken (since my major changes  
yesterday).  If any of the regulars can diagnose it, that would be  
most helpful :)

To initialize kamap to a certain position and zoom level, you can use  
the kaMap.initialize function and pass the center point and scale as  
the third argument:

myKaMap.initialize( null, null, lon+","+lat+","+scale );

to add a marker at that location, you will need to wait until after  
the map is initialized.  As this happens asynchronously, you will  
need to do something like the following:

var myKaMap, myCanvas;

function myOnLoad()
{
     ...
     myKaMap.registerForEvent( KAMAP_MAP_INITIALIZED, null,  
myMapInitialized );
     ...
}

function myMapInitialized()
{
     myCanvas = myKaMap.createDrawingCanvas( 500 );

     var marker = document.createElement( 'img' );
     marker.src = 'images/marker.png';

     myKaMap.addObjectGeo( myCanvas, lon, lat, marker );
}

Cheers

Paul
