|
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. |
