Hi,
having complete API looks like a good idea. In the meantime, you can:
PdfName name = "xxx";
if (document->GetInfo()->GetObject()->GetDictionary().HasKey(name)){
const PdfObject *object = document->GetInfo()->GetObject()->
GetDictionary().GetKey(PdfName(name));
if (object && (object->IsString() || object->IsHexString())) {
std::wstring wstr = object->GetString().GetStringW();
// wstr contains the value;
}
}
I'm not going to add the API there, I'm only showing that with PoDoFo
you can achieve anything by using low-level API, without relying on
provided higher-level APIs by PoDoFo itself. It's good to be aware of
it, because there are many things which can be done in PDF for which
PoDoFo doesn't have higher-level API at all.
Bye,
