Reorder pages

GroupDocs.Viewer allows you to reorder the document pages. The order of the pages in the source document is never changed, instead, the API applies reordering to the resultant PDF document.

To reorder the pages:

• Instantiate Viewer object;
• Create PdfViewOptions;
• Call View method specifying desired page numbers order.

The following code snippet shows how to reorder pages.

using (Viewer viewer = new Viewer("sample.docx"))            
{     
    PdfViewOptions viewOptions = new PdfViewOptions();
 
    // Pass page numbers in the order you want to render them                                       
    viewer.View(viewOptions, 2, 1);
}
