Hi,
I'm making a new GML layer from an existing layer. For some reason the
CopyLayer method leaves adjusted fields out but CreateField,
CreateFeature sequence does not. I guess they should be identical?
i.e.
my $datasource = Geo::OGR::Open('Pg:...');
my $l = $datasource->ExecuteSQL('...');
my $gml = Geo::OGR::Driver('GML')->Create('/vsistdout/');
$gml->CopyLayer($l, 'a');
leaves fields like "a b" out, while
my $datasource = Geo::OGR::Open('Pg:...');
my $l = $datasource->ExecuteSQL('...');
my $gml = Geo::OGR::Driver('GML')->Create('/vsistdout/');
my $l2 = $gml->CreateLayer('test');
my $d = $l->GetLayerDefn;
for (0..$d->GetFieldCount-1) {
my $f = $d->GetFieldDefn($_);
$l2->CreateField($f);
}
$l->ResetReading;
while (my $f = $l->GetNextFeature) {
$l2->CreateFeature($f);
}
works ok (and prints out warnings about the field name adjustments)
I tried to look into what the CopyLayer method generic driver does
differently but could not tell.
Any ideas?
Ari
