Adding an image to a PDF using iTextSharp and scale it properly

Question

here s my code  It correctly adds the pictures I want and everything works except that the images are using their native resolution  so if the image is big it s being cropped to fit the page   Is there some way to have the picture use like a Zoom feature to stretch to fit  but also maintain the aspect ratio  There has to be something I m missing there   P  Here s a picture to illustrate the problem    using System  using System IO  using iTextSharp text  using iTextSharp text pdf  using System Drawing  using System Collections Generic   namespace WinformsPlayground       public class PDFWrapper               public void CreatePDF List lt System Drawing Image gt  images                        if  images Count  gt   1                                Document document   new Document PageSize LETTER                   try                                           step 2                         we create a writer that listens to the document                        and directs a PDF-stream to a file                      PdfWriter GetInstance document  new FileStream  Chap0101 pdf   FileMode Create                            step 3  we open the document                     document Open                         foreach  var image in images                                                iTextSharp text Image pic   iTextSharp text Image GetInstance image  System Drawing Imaging ImageFormat Jpeg                           document Add pic                           document NewPage                                                            catch  DocumentException de                                        Console Error WriteLine de Message                                     catch  IOException ioe                                        Console Error WriteLine ioe Message                                         step 5  we close the document                 document Close

I solved it using the following   foreach  var image in images        iTextSharp text Image pic   iTextSharp text Image GetInstance image  System Drawing Imaging ImageFormat Jpeg        if  pic Height  gt  pic Width                  Maximum height is 800 pixels          float percentage   0 0f          percentage   700   pic Height          pic ScalePercent percentage   100             else                 Maximum width is 600 pixels          float percentage   0 0f          percentage   540   pic Width          pic ScalePercent percentage   100              pic Border   iTextSharp text Rectangle BOX      pic BorderColor   iTextSharp text BaseColor BLACK      pic BorderWidth   3f      document Add pic       document NewPage
