    copied!<p>I'm able to save the captured image from a barcode scanner using this code:</p> <pre><code> Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog(); dlg.DefaultExt = ".jpg"; dlg.Filter = "JPEG Images (.jpg)|*.jpg|All files (*.*)|*.*"; if (dlg.ShowDialog() == true) { using (FileStream file = File.OpenWrite(dlg.FileName)) { file.Write(e.ImageBuffer, 0, e.ImageSize); } } </code></pre> <p>However, I would like to display the captured image using WPF but I get a distorted image.</p> <pre><code>private void _barcodeScannerInstance_SavePhotoEvent(object sender, ImageEventArgs e) { SetBitmap(e.ImageBuffer, 350, 263, 96); } private void SetBitmap(byte[] image, int width, int height, int dpi) { MainWindow.Instance.Dispatcher.Invoke(DispatcherPriority.Normal, (ThreadStart)delegate() { BitmapSource bitmapSource = BitmapSource.Create( width, height, (double)dpi, (double)dpi, PixelFormats.Bgr24, null, image, ((width * 24 + 31) &amp; ~31) &gt;&gt; 3); HwModeScreen.BarcodeImageCanvas.Children.Clear(); Image myImage = new Image(); myImage.Width = HwModeScreen.BarcodeImageCanvas.ActualWidth; myImage.Height = HwModeScreen.BarcodeImageCanvas.ActualHeight; myImage.Stretch = Stretch.Fill; myImage.Source = bitmapSource; HwModeScreen.BarcodeImageCanvas.Children.Add(myImage); }); </code></pre> <p>Here is the image I see. It should be a black and white picture of a kleenex box.</p> <p><img src="https://img.photobucket.com/albums/v85/Keyoh/distortedphoto.jpg" alt="alt text"></p> <p>Here is the saved jpg file: <img src="https://img.photobucket.com/albums/v85/Keyoh/barcodephoto2.jpg" alt="alt text"></p>
