Notes		  

This method provides a simple method for remapping the pages in a document. It can be used for reordering, copying or deleting pages.

It accepts a list of page numbers and reorders the pages in the document so that they match these page numbers. If a number is repeated more than once, the page is duplicated. If a number is omitted, the page is deleted.

Page numbers can be delimited using spaces, commas or semicolons. The first page in a document is page one. So to reverse a four page document, you might use "4 3 2 1".

If a page is duplicated and it contains Form fields, you may want to call MakeFieldsUnique to avoid sharing fields across pages.

 

    

Example		  

The following code snippet illustrates how one might reverse all the pages in a document.

 

using var doc = new Doc(); doc.Read(Server.MapPath("../mypics/sample.pdf")); doc.FontSize = 500; doc.Color.String = "255 0 0"; doc.TextStyle.HPos = 0.5; doc.TextStyle.VPos = 0.3; int count = doc.PageCount; var pages = new List<int>(); for (int i = 1; i <= count; i++) {   doc.PageNumber = i;   doc.AddText(i.ToString());   pages.Add(count - i + 1); } doc.RemapPages(pages.ToArray()); doc.Save(Server.MapPath("docremappages.pdf"));
