Syntax


        public 
        Document(
        



BinaryReader
         reader

        )

Parameters



BinaryReader
 reader

The reader from which the document is read.

The document should have no open password set.

This method gives you full control over how the document is read. It requires that the binary reader remains open during the lifetime of the document.

Provided that the argument binary reader is seekable, information will be read from the PDF file on demand. E.g. if one hits page 10, we seek to the correct position, skipping all other pages, and we return page 10. If after that a request references page 5, we seek back and read that page. This means that one should not close/dispose the binary reader during the whole session one needs the document, pages, bookmarks, or other info extracted from it.

If the binary reader is not seekable, we will read information eagerly, i.e., the entire document will first be read into memory before we access it.

Sample code: FileStream fileStream = new FileStream( @"in.pdf", FileMode.Open, FileAccess.Read ); BinaryReader reader = new BinaryReader( fileStream ); Document source = new Document( reader );
