Zooms the map around a given center on the screen.

Namespace:  ESRI.ADF.UI
 

Syntax

function zoom (
	scaleFactor : Number, 
	center : Point, 
	animate : Boolean
) : Object

Parameters

scaleFactor
Type: [T:J#Number]
Amount to zoom in on the map. This value may be adjusted to fit a tiled layer.
center
Type: ESRI.ADF.Geometries..::.Point
Center point to zoom around in map coordinates. This point will stay fixed during zoom If null, the center of the current view is used.
animate
Type: [T:J#Boolean]
Specifies whether animation should be used for zooming. Default is true.

Return Value

True if a zoom was performed, false if not (no scale change). Returns undefined is the zoom was queued up.

Remarks

The scaleFactor might be adjusted to fit the closest pixel resolution if the map contains tiled resources. If the adjusted scaleFactor is 1, the map will return false and you should call panTo instead.
