   Point centerPoint
)

Parameters

scaleFactor

Positive to zoom-in, negative to zoom-out.

centerPoint

Map's new center point.

Return Value

See Zoom(double) for discussion of how scaleFactors work with zooming in or out. This method allows zooming and re-centering the map in one operation. Since all zoom and pan methods cause the ArcIMS server to generate a map image, using this method can save server resources by limiting the number of images drawn.

Any Zoom, Pan, CenterAt or Draw method which changes the map extent also changes the map extent for the MapView.
