This example will transform a vector dataset from spatial reference system EPSG 2392 to EPSG 2393. The geometries are translated by (dx, dy) = (2500000, 6600000) before applying the transformation.
$dsname = shift @ARGV;
$lname = shift @ARGV;
$layer1 = $datasource->Layer($lname) or die;
$dsname = shift @ARGV;
$lname = shift @ARGV;
$layer2 = $datasource->CreateLayer
({ Name => $lname, SRS => $sr2, GeometryType => $layer1->GetLayerDefn->GeometryType});
$layer2->Schema( $layer1->Schema );
$layer1->ResetReading();
while ($feature = $layer1->GetNextFeature()) {
my $geom = $feature->GetGeometry();
$geom->Move(2500000, 6600000);
$geom->Transform($tr);
$layer2->InsertFeature($feature);
}
