Hello again Dom!
I have found what I think is a bug in the way that PdfInfo returns its
String entries.
The function in question is PdfInfo::GetStringFromInfoDict() which
ensures that the PdfObject its returning is in fact a string before
calling GetString() on that object. If the PdfObject is of any other
type the function returns NULL.
return pObj && pObj->IsString() ? pObj->GetString() : PdfString::StringNull;
However if pObj is a Hex String, the function incorrectly returns
StringNull, even though (as I understand it) calling GetString() on a
hex string is perfectly safe and allowable.
All that we need to do here is add a second test for the case where pObj
is a Hex string:
return pObj && (pObj->IsString() || pObj->IsHexString()) ?
pObj->GetString() : PdfString::StringNull;
I have attached a patch for this bug.
Cheers!
