Remarks
Load a document, configure the geometry, then Save(String) / GetDocument. Each source page is drawn scaled and aligned onto a new page. The resized document keeps what the loaded document carries beyond its pages: annotations, links, form fields, bookmarks, named destinations, the open action, page labels, attachments, document information, viewer preferences and XMP metadata, with every page reference and coordinate remapped to the resized geometry.
Example
Copy
PdfResizeManager manager = new PdfResizeManager();
manager.Load("a4.pdf");
manager.PageSize = PdfCustomPageSize.Letter;
manager.PageMargins = new PdfMargins(36);
manager.Save("letter.pdf");
manager.Close();
