Public Sub AnnContainer_LockPicture(ByVal container As AnnContainer)
   ' we are going to create a new lock image that is 20 by 20 red ellipse with a blue cross inside it.
   Dim btmp As Bitmap = New Bitmap(20, 20, PixelFormat.Format32bppArgb)
   Dim g As Graphics = Graphics.FromImage(btmp)
   Try
      ' fill the image with a white color
      g.FillRectangle(Brushes.White, New Rectangle(0, 0, 20, 20))
      g.FillEllipse(Brushes.Red, New Rectangle(0, 0, 20, 20))
      g.DrawLine(Pens.Blue, 0, 0, 20, 20)
      g.DrawLine(Pens.Blue, 20, 0, 0, 20)
   Finally
      CType(g, IDisposable).Dispose()
   End Try
   ' create an annotation picture for this image, use white as the transparent color
   Dim pic As AnnPicture = New AnnPicture(btmp)
   pic.TransparentMode = AnnPictureTransparentMode.UseColor
   pic.TransparentColor = Color.White

   ' use this picture to draw all locked objects in this container
   container.LockPicture = pic
End Sub
C#Copy Code
public void AnnContainer_LockPicture(AnnContainer container) 
{ 
   // we are going to create a new lock image that is 20 by 20 red ellipse with a blue cross inside it. 
   Bitmap btmp = new Bitmap(20, 20, PixelFormat.Format32bppArgb); 
   using (Graphics graphics = Graphics.FromImage(btmp)) 
   { 
      // fill the image with a white color 
      graphics.FillRectangle(Brushes.White, new Rectangle(0, 0, 20, 20)); 
      graphics.FillEllipse(Brushes.Red, new Rectangle(0, 0, 20, 20)); 
      graphics.DrawLine(Pens.Blue, 0, 0, 20, 20); 
      graphics.DrawLine(Pens.Blue, 20, 0, 0, 20); 
   } 
   // create an annotation picture for this image, use white as the transparent color 
   AnnPicture pic = new AnnPicture(btmp); 
   pic.TransparentMode = AnnPictureTransparentMode.UseColor; 
   pic.TransparentColor = Color.White; 
 
   // use this picture to draw all locked objects in this container 
   container.LockPicture = pic; 
}

Remarks

All objects inside the container will use this picture when drawing the object if the object is locked.

The container uses a picture of a "lock" that is created by default. You can change this default picture by using this property.
