+**RadPdfViewer** in the Telerik UI for WinForms suite is purposed to display PDF files.

+
+## Solution 
+
+**RadPdfViewer** exposes two methods that allows you to export singe page or the entire document to an image:
+
+* **ExportPage**: exports the specified page to an image.
+* **ExportPages**: exports the entire document to an image.
+
+The ExportPage method will be used in the following code snippet:
+
+````C#
+
+static void Main(string[] args)
+{
+    Telerik.WinControls.UI.RadPdfViewer rViewer = new Telerik.WinControls.UI.RadPdfViewer();
+    rViewer.DocumentLoaded += RViewer_DocumentLoaded;
+    rViewer.LoadDocument(@"..\..\WinForms PdfViewer.pdf");
+    rViewer.LoadElementTree();
+    System.Windows.Forms.Application.DoEvents();
+}
+private static void RViewer_DocumentLoaded(object sender, System.EventArgs e)
+{
+    string filePath = @"..\..\page";
+    Telerik.WinControls.UI.RadPdfViewerElement pdfViewerElement = sender as Telerik.WinControls.UI.RadPdfViewerElement;
+    if (pdfViewerElement != null)
+    {
+        for (int i = 0; i < pdfViewerElement.Document.Pages.Count; i++)
+        {
+            System.Drawing.Image imagePage = pdfViewerElement.ExportPage(i, 1, true, System.Drawing.Imaging.ImageFormat.Jpeg);
+            imagePage.Save(filePath + i + ".jpg");
+        }
+    }
+}
+
+````
+````VB.NET
+
+ Sub Main()
+
+     Dim rViewer As Telerik.WinControls.UI.RadPdfViewer = New Telerik.WinControls.UI.RadPdfViewer()
+     AddHandler rViewer.DocumentLoaded, AddressOf RViewer_DocumentLoaded
+     rViewer.LoadDocument("..\..\WinForms PdfViewer.pdf")
+     rViewer.LoadElementTree()
+     System.Windows.Forms.Application.DoEvents()
+ End Sub
+
+ Private Sub RViewer_DocumentLoaded(ByVal sender As Object, ByVal e As System.EventArgs)
+     Dim filePath As String = "..\..\page"
+     Dim pdfViewerElement As Telerik.WinControls.UI.RadPdfViewerElement =
+         TryCast(sender, Telerik.WinControls.UI.RadPdfViewerElement)
+
+     If pdfViewerElement IsNot Nothing Then
+
+         For i As Integer = 0 To pdfViewerElement.Document.Pages.Count - 1
+             Dim imagePage As System.Drawing.Image = pdfViewerElement.ExportPage(i, 1,
+                                                                                 True, System.Drawing.Imaging.ImageFormat.Jpeg)
+             imagePage.Save(filePath & i & ".jpg")
+         Next
+     End If
+ End Sub  
+
