Thank you again.
Just to close definitely this discussion, do you think the following steps
are correct in this case? 
- Got the Upper Left corner of the image with
GetGeoTransform(adfGeoTransform) 
- Found out the others corners in this way: 
double miny = adfGeoTransform[3] + width*adfGeoTransform[4] +
height*adfGeoTransform[5]; 
double maxx = adfGeoTransform[0] + width*adfGeoTransform[1] +
height*adfGeoTransform[2]; 
- Convert all these 4 points related to the corners with TransformPoint(); 

Especially the point where I found the other corners, by moving in the
raster space.

Thank you,
have a nice day
MATT
