Hi All,

I'm facing in  strange result using gdaltransform. What I'm doing is to try
to trasform coordinates from WGS84 to Gauss-Boaga:

gdaltransform.exe -s_srs "WGS84" -t_srs "+proj=tmerc +ellps=intl +lat_0=0
+lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +units=m
entering lon and lat
>7,69746 45,106977<enter>
it gives
1342393.88434212 4984915.97865081 -47.0342488819733
doing the same transformation with qgis (same parameters), I have
1397559,446 4995677,02
that is quite near to the target expected also checking out in map.

Do we know the reason of this delta? Do I have to set any other correction
