IARMap.ZoomOut Method

[C#]
public void ZoomOut (
    double factor
);

Product Availability

Available with ArcGIS Desktop. Requires Publisher Extension.

Description

Zooms out on the ARMap from the center of its current visible extent by a specified factor. This factor represents the ratio between the new visible extent and the previous visible extent and will cause the MapScale property to change. For example, zooming in by a factor of 2, is the same as zooming out by a factor of 0.5 and vice versa.
