Hello everybody,
I'm using GDAL 1.8.0 with Java, and I do not why but I got different results
with TransformPoint with same inputs. Maybe I'm wrong, anyway see this:

Upper Left = (/258321.25943477/, 655225.28062628)
Abs: *-24.39163021771631*, 66.2996405709653

Lower Left = (/258321.25943477/, 574605.28062628)
Abs: *-24.24282066963955*, 65.5792295908428

Upper Right = (/339151.25943477,/ 655225.28062628)
Abs: *-22.593238696114604*, 66.35110363848813

Lower Right = (/339151.25943477,/ 574605.28062628)
Abs: *-22.493807890469444*, 65.62928831950212

Those are the corners of my image, and as you can see when I try to convert
with TransformPoint(X,Y), I got different value for example with static X
and variable X. 

Thank you for your help,
Mattia
