Adding a Buffer Around a MapPoint Web Service Map

When a user requests a map containing a certain set of points, you can use one of four classes to return a map view: ViewByBoundingLocations, ViewByHeightWidth, ViewByScale, or ViewByBoundingRectangle. Only one of these classes, ViewByBoundingLocations, provides a buffer. This buffer is meant to prevent the icon images from being truncated and from appearing on the edges of the map. The default buffer, which is fixed, can usually prevent icons from being truncated. However, in certain situations, the default buffer may not work.

This article describes how to use the ViewByBoundingRectangle class to add a buffer around MapPoint Web Service maps, ensuring that all map icons are shown in their entirety.
