52@english
53This function allows you to obtain the height of a given ''TILE'' or a given
54set of ''TILES''. The width is expressed in tiles. If the parameter is a
55``TILESET``, this is the height of a single tile.

57@italian
58Questa funzione permette di ottenere l'altezza della tile (''TILE'')
59o delle tiles (''TILES'') date, espressa in tiles. Se il parametro è un
60''TILESET'', questa sarà l'altezza di una singola tessera.
