In the info.xml I need such informations :

<envelope crs =3D "GEOGCS['WGS 84',=20
  DATUM['World Geodetic System 1984',=20
    SPHEROID['WGS 84', 6378137.0, 298.257223563,=20
AUTHORITY['EPSG','7030']],=20
    AUTHORITY['EPSG','6326']],=20
  PRIMEM['Greenwich', 0.0, AUTHORITY['EPSG','8901']],=20
  UNIT['degree', 0.017453292519943295],=20
  AXIS['Geodetic latitude', NORTH],=20
  AXIS['Geodetic longitude', EAST],=20
  AUTHORITY['EPSG','4326']]" srsName =3D "EPSG:4326" >
<pos>580991.6875 2423886.75</pos>
<pos>585996.25 2428891.25</pos>
</envelope>

In my .tfw file, I've got :

            1.3229166666
            0.0000000000
            0.0000000000
           -1.3229166665
       580991.6614583330
      2428891.3385416698

So I need to calcule the 2423886.75 and the 585996.25 if I say that=20
580991.6875 is the same as 580991.6614583330 and that 2428891.25 is the=20
same as  2428891.3385416698

That's why I though I need geotools ?
