I get error:

from code :

 public void LoadImage (String imageName)
		{
			int Width = 800;
			int Height = 600;
       		                            
			byte[] buffer = new byte[Width * Height * 3];

			using (System.IO.Stream iStream = Assets.Open ("800x600.bmp")) {     
				iStream.Read (buffer, 0, buffer.Length);
	            
			}
			GCHandle handle = GCHandle.Alloc (buffer, GCHandleType.Pinned);		
			Image<Gray, Byte> grey = new Image<Gray, byte>(Width, Height, Width, handle.AddrOfPinnedObject());

			CvInvoke.cvCanny (grey, grey, 100, 60, 3);
}

Funny enough error shows on Image... while if I remove CvInvoke line it loads all .so files correctly
Help im stuck
