public class DTEDFrameCacheLayer
The DTEDFrameCacheLayer fills the screen with DTED data. To view the DTED iamges, the projection has to be set in an ARC projection, which OpenMap calls the CADRG or LLXY projection. In Gesture mode, clicking on the map will cause the DTEDFrameCacheLayer to place a point on the window and show the elevation of that point. The Gesture response is not dependent on the scale or projection of the screen.
The DTEDFrameCacheLayer uses the DTEDCacheHandler to get the images it needs. The DTEDFrameCacheLayer receives projection change events, and then asks the cache handler for the images it needs based on the new projection. The DTEDFrameCacheLayer also relies on properties to set its variables, such as the dted frame paths (there can be several at a time), the opaqueness of the frame images, number of colors to use, and some other display variables. The DTEDFrameCacheLayer properties look something like this:
NOTE: Make sure your DTED file and directory names are in lower case. You can use the com.bbn.openmap.layer.rpf.ChangeCase class to make modifications if necessary.

Occasionally it is necessary to abort a prepare call. When this happens, the map will set the cancel bit in the LayerThread, (the thread that is running the prepare). If this Layer needs to do any cleanups during the abort, it should do so, but return out of the prepare asap.
