Export PDF file to ImageSource in WPF
The WPF Image control allows you to display images in an application. You can use GemBox.Pdf to convert a PDF page to an image.
The following example shows how to convert a PDF page to an ImageSource instance and attach it to WPF's Image control.

</Menu>
<Border Margin="10" BorderBrush="Black" BorderThickness="1">

fileDialog.Filter = "PDF files (*.pdf)|*.pdf";
if (fileDialog.ShowDialog() == true)
{
using (var document = PdfDocument.Load(fileDialog.FileName))
{
this.ImageControl.Source = document.ConvertToImageSource(SaveOptions.Image);
}
}
}
}

End Sub
Private Sub MenuItem_Click(sender As Object, e As RoutedEventArgs)
Dim fileDialog = New OpenFileDialog()
fileDialog.Filter = "PDF files (*.pdf)|*.pdf"
If (fileDialog.ShowDialog() = True) Then
Using document = PdfDocument.Load(fileDialog.FileName)
Me.ImageControl.Source = document.ConvertToImageSource(SaveOptions.Image)
