     4 /**  convertMap.h

     5 Functions for converting  from one Map form to another 

     6 and extracting smaller maps. There are four polymorphic

     7 functions.   The general format is

     8 

     9 convertMap(MapType * source,MapType * target, Point ul, Point lr)

    10 

    11 MapTypes can be - BitMap, RLEMap, or VRLEMap

    12 source - the map to be converted from

    13 target - The map to be converted to.  Memory will be allocated

    14          for target's contents. 

    15 ul and lr mark a range to copy.   If either are the global var NOPNT,

    16 the entire map will  be copied.

    17 

    18 Functions return a MapStatus which will be VALID or OTHERERROR

    19 if there was an error in the conversion.  An error might be due

    20 to a user specifying an out of range ul and lr.
