{ 
   MyForm2 form = new MyForm2(); 
   form.ShowDialog(); 
} 
 
class MyForm2 : Form 
{ 
   RasterPictureBox thePictureBox; 
 
   public MyForm2() 
   { 
      // Create the raster PictureBox 
      thePictureBox = new RasterPictureBox(); 
      thePictureBox.Dock = DockStyle.Fill; 
      thePictureBox.BorderStyle = BorderStyle.Fixed3D; 
      thePictureBox.UseDpi = false; 
 
      // Set the paint properties 
      RasterPaintProperties p = new RasterPaintProperties(); 
      p.PaintDisplayMode = RasterPaintDisplayModeFlags.Bicubic; 
      p.PaintEngine = RasterPaintEngine.GdiPlus; 
      p.UsePaintPalette = true;

      thePictureBox.Image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "eye.gif")); 
      codecs.Dispose(); 
 
      thePictureBox.FrameChanged += new EventHandler<RasterPictureBoxFrameChangedEventArgs>(thePictureBox_FrameChanged);
