Selon ahmet temiz <[email protected]>:
GetFeature(n) returns the feature such as feature.GetFID() == n, so attribute or
spatial filter are not taken into account.
If you want to iterate over the feature of the layers, and take into account
filters, you have to use GetNextFeature(), until it returns null.
