Functions | |
| bool | GetHeightmapDimensions (char *filename, uint *x, uint *y) |
| Get the dimensions of a heightmap. | |
| void | LoadHeightmap (char *filename) |
| Load a heightmap from file and change the map in his current dimensions to a landscape representing the heightmap. | |
| void | FlatEmptyWorld (byte tile_height) |
| Make an empty world where all tiles are of height 'tile_height'. | |
| void | FixSlopes () |
| This function takes care of the fact that land in OpenTTD can never differ more than 1 in height. | |
