Problem with saving annotation...

Please could you help as I have been trying to do this for hours. I am able to draw annotation using annAutomation, however I am able to save the image but not with the annotations in it, see code below:

' Leadtools variables
' Automation Manager used in managing the automation mode.
Private annAutomationManager As AnnAutomationManager
Private automation As AnnAutomation
Private annCodecs As AnnCodecs
Private tagFormat As AnnCodecsTagFormat

Private Sub frmCommManager_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Lead tools info
' Lead tools info
' enable 14.5 new rotate control points
' create and set up the automation manager
annAutomationManager = New AnnAutomationManager

' enable 14.5 preserve aspect ratio
annAutomationManager.MaintainAspectRatio = True

' You can instruct the manager to create the default (all) automation objects.
' comment out the call to CreateMyAutomationObjects and call this instead:
annAutomationManager.CreateDefaultObjects()

' create the toolbar and add it to the form
annAutomationManager.CreateToolBar()
'Controls.Add(annAutomationManager.ToolBar)

' set up the automation (will create the container as well)
automation = New AnnAutomation(annAutomationManager, Me.rasterViewer)

' set up this automation as the active one
automation.Active = True
end sub

Public Sub save()
Dim Codecs As RasterCodecs = New RasterCodecs()
RasterCodecs.CodecsPath = "C:\Program Files\LEAD Technologies, Inc\LEADTOOLS EVAL 14.5\Bin\Dotnet\v11"
Dim memoryStream As New System.IO.MemoryStream
Dim bits As Integer = Me.rasterViewer.Image.BitsPerPixel

Codecs.Save(New RasterImage(Me.rasterViewer.Image), "C:\temp\ann1.tif", RasterImageFormat.Tif, bits)

Dim tag As RasterTagMetadata = annCodecs.SaveToTag(automation.Container, tagFormat)
Codecs.WriteTag("C:\temp\ann1.tif", 1, tag)
end sub

Could you please point out where I am going wrong and if possible correct my sample code.

I am using v14.5 .Net Class

Thanks in advance

What build of Leadtools.dll are you using (14.5.0.x)?

Are you getting any errors?

Why are you creating a new RasterImage in the Codecs.Save call?  Assuming that Me.rasterViewer is a RasterImageViewer, the Image property already is a RasterImage and you don't need to pass it to the constructor.  I don't know if this is causing problems, but it's certainly frivolous.

Have you been able to get the help file's example for SaveToTag to work?

I am using 14.5.0.68

I am not getting any errors, all code seems to be processed.

To be honest I am having a really hard time trying to get this to save, hence the request for an example. I have been unable to get the SaveToTag to work even when working through the examples in the help file.

Your help in this matter would be greatly appreshiated.

I've made a small working project based off of your code to help you get started.  You need to:

1. Click the Load Image button to load an image without annotations
2. Draw some annotations on the image.
3. Click the Save Image and Annotatoins button
4. Remove the annotations
5. Click the Load Image and Annotations button.

If this does not work, then please send an email to support@leadtools.com in order to get the download instructions for the latest patch.  For verification purposes, I need you to include the following information:
