A PDF document object can be constructed with an existing PDF file from file path, memory buffer, a custom implemented FSFileReaderCallback object and an input file stream. And then call function pdf::PDFDoc::load: or PDFDoc::startLoad:is_cache_stream:pause: to load document content. This class offers functions to retrieve different part of a PDF document. For example:
This class also offers functions for features, such as saving current document as another PDF file, importing pages from another PDF file, setting security handler in order to save encrypted PDF file, and so on.
This class object can also be used to construct objects of other classes in order to access specified information in PDF document:
