## com.bbn.openmap.image
Class ImageMaster

    java.lang.Object
      com.bbn.openmap.image.ImageMaster

public class ImageMaster
extends java.lang.Object

The ImageMaster is an organizer for running the ImageServer to create one or more images. It relies on a properties file, which sets up a series of entries for an ImageServer. Each entry has parameters for setting up a projection for an image, a parameters for a URL for the ImageServer to use to set up the layers for an image, and a parameter to set the name and path of the output image file.

Each map entry in the ImageServer has parameters for the projection and layer properties to use for the map image, and the size, location and format of the output image.

Nested Class Summary
`class` | `ImageMaster.ImageMasterHelper` The ImageMasterHelper contains an ImageServer, and acts like the ImageReceiver to create the Image file when the bits are ready.
