A PDF dictionary object is an associative table containing pairs of objects, known as entries of the dictionary. The first element of each entry is the key, and it must be a PDF name object. The second element is the value, and it can be any kind of PDF object, including another dictionary. In the same dictionary, no two entries should have the same key. For more details, please refer to Section 3.2.6 "Dictionary Objects" in <PDF Reference 1.7>.
Class FSPDFDictionary is derived from FSPDFObject and offers functions to create a new PDF dictionary object and get/set entries in a PDF dictionary object.
+ (FSPDFDictionary *) create |
Create a new dictionary object.
Please call function PDFObject::destroy to release the created object if it has not been added/set into PDF document or other PDF object and will not be used any more.
