Hello Everyone I want to use DocumentViewer control to display Multipage Tiffs.The code i have written is the following...

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace Tiff_Viewer

 /// <summary>
 /// Interaction logic for MainWindow.xaml
 /// </summary>
 public partial class MainWindow : Window
 
 private System.Windows.Controls.Image _Image;
 private System.Windows.Documents.FixedDocument _FixedDocument;
 private System.Windows.Documents.FixedPage _FixedPage;
 private System.Windows.Documents.PageContent _PageContent;
 public MainWindow()
 
 InitializeComponent();
 


 private void testbutton_Click(object sender, RoutedEventArgs e)
 
 try
 
 this._Image = new Image();
 FileStream ImageStream = new FileStream("C:\Users\ttsa\Desktop\DocumentViewerTest\002544-20180907.tif", FileMode.Open, FileAccess.Read, FileShare.Read);
 TiffBitmapDecoder ImageDecoder = new TiffBitmapDecoder(ImageStream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);

 //BitmapSource bitmapSource = ImageDecoder.Frames[0];
 this._Image.Source = ImageDecoder.Frames[0];
 //this._Image.Source = new BitmapImage(new Uri("C:\Users\ttsa\Desktop\DocumentViewerTest\AAA0011A.tif", UriKind.Relative));
 this._Image.Stretch = Stretch.None;
 this._Image.Margin = new Thickness(20);

 this._FixedPage = new System.Windows.Documents.FixedPage();
 this._FixedPage.Width = 1000;
 this._FixedPage.Height = 1000;
 this._FixedPage.Children.Add(this._Image);

 this._PageContent = new System.Windows.Documents.PageContent();
 this._PageContent.Child = this._FixedPage;

 this._FixedDocument = new FixedDocument();
 this._FixedDocument.Pages.Add(this._PageContent);

 DocumentViewer.Document = this._FixedDocument;
 //DocumentViewer.LastPage();
 
 catch (Exception fd)
 
 System.Windows.MessageBox.Show(fd.Message);

I have tried to take and display only one frame-page from the TIFF.However when i run the program it does show the page i want BUT when i move the cursor of the mouse inside the Document Viewer and specifically inside the image i keep getting the following error:

"System.IO.FileNotFoundException: 'Could not find file
'C:UsersttsaDesktopTIFF_ViewerTiff_ViewerTiff_ViewerbinDebugimage'.'".

I have tried almost everything and i cant find a way to fix this.
Does anyone knows anything about this? Is there something i can do to fix it?
Or else does anyone knows another way to display multipage tiff to DocumentViewer???

Thanks in advance!!!

I did make a copy of your code and you are not the only one with the exception.
I don't know why the documentviewer trows the 'File not found exception', if someone can explain this it would be appreciated.

One way I have found to solve this is to put the image stream inside a BitmapImage before loading it in the document viewer. The only problem is that I can't get this to work with a multipage Tiff:

BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.StreamSource = ImageStream;
bi.EndInit();
this._Image.Source = bi;

One way to make it work with a multipage tiff is kind of a hack, you could just create the file the program is asking for. It needs to be a file named Image witout a file extension, also it needs to be a Tiff file structure. It can be any tiff but for this I did make a copy of the tiff we show in the documentviewer. When there is already a Image file, there is no need to copy it again.

string pathToTiff = @"C: UsersdeveloperDesktoptemptest.tif";

this._Image = new Image();
FileStream ImageStream = new FileStream(pathToTiff, FileMode.Open, FileAccess.Read, 
FileShare.Read);
TiffBitmapDecoder ImageDecoder = new TiffBitmapDecoder(ImageStream, 
BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);

this._FixedDocument = new FixedDocument();

if (!File.Exists(AppDomain.CurrentDomain.BaseDirectory + @"Image"))

 File.Copy(pathToTiff, AppDomain.CurrentDomain.BaseDirectory + @"Image", true);


foreach (BitmapFrame f in ImageDecoder.Frames)

 this._Image = new Image();
 this._Image.Source = f.Clone(); ;
 this._Image.Stretch = Stretch.None;
 this._Image.Margin = new Thickness(20);

 this._FixedPage = new System.Windows.Documents.FixedPage();
 this._FixedPage.Width = 1000;
 this._FixedPage.Height = 1000;
 this._FixedPage.Children.Add(this._Image);

 this._PageContent = new System.Windows.Documents.PageContent();
 this._PageContent.Child = this._FixedPage;
 this._FixedDocument.Pages.Add(this._PageContent);

documentViewer.Document = this._FixedDocument;

Im assuming, that the path shown in your exception message, is your actual FileStream path. You might need to add the extension of the file aswell (for example: "..Debugimage.tif").
