This object represents a document information dictionary which contains metadata from the PDF file. The object is a collection of DocumentInformationDictionaryItem objects. The DocumentInformationDictionary may exist either as an independent object or as a subobject of the DocumentContentInfo object.
  • The indexing of ABBYY FineReader Engine collections starts with 0.
  • The foreach statement in C# (for each in Visual Basic .NET) can be used to manipulate the collection.
  • If the values of the Author, Keywords, Subject or Title properties of the DocumentContentInfo object are not empty strings, the values of these properties are used instead of the corresponding items of the DocumentInformationDictionary object.
