Describe

This example shows how to define a map's animation when the user zooms in or out. Zoomduration and Zoomrate are Dojo animation properties that determine the animation's duration and frame refresh rate. These property units are milliseconds, and the default value of Zoomduration is 250,zoomrate the default value is 25.

In this case, you can get a better look at the data and the app by adjusting these properties. For example, if the map takes a long time to load, you can increase the zoomduration so that the user sees a short or distorted screen time while waiting for the zoom map to load. Conversely, if the map loads quickly, you can lower the zoomduration value to give the map a quicker feel.

This example shows how to change the default symbol for the Zoom box that is displayed when you hold down the SHIFT key while you click and drag the mouse. The ability to define arbitrary fill symbols as esriconfig inside the Zoomsymbol. As shown in this line of code:

EsriConfig.defaults.map.zoomSymbol = {"Color": [255,255,255,127], "outline": {"color": [255,0,0,255], "width": 1.5, " Style ":" Esrislsdash "}," style ":" Esrisfssolid "};
