I can clone RasterImageViewer Transform to AnnContainer Transform when implementing Non Automated Annotation Program.Codes:
Private Sub RasterImageViewer1_TransformChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RasterImageViewer1.TransformChanged
If (Not IsNothing(annContainerObj)) Then
annContainerObj.Transform = RasterImageViewer1.Transform.Clone()
End If
End Sub

Now I try to create annotations with Microsoft.Ink in a tablet application.I can't just clone RasterImageViewer1.Transform to inkOverlay.Renderer.How to make it work?Codes:
Private inkOverlay As Microsoft.Ink.InkOverlay
inkOverlay = New Microsoft.Ink.InkOverlay(_RasterImageViewer1)
inkOverlay.EditingMode = Microsoft.Ink.InkOverlayEditingMode.Ink
inkOverlay.Enabled = true

Private Sub RasterImageViewer1_TransformChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RasterImageViewer1.TransformChanged

Using m As Matrix = RasterImageViewer1.GetTransformWithDpi()
inkOverlay.Renderer.SetViewTransform(m)
End Using

End Sub

I'm not familiar with Microsoft.Ink, but if what you want is to obtain the coordinates of an annotation object, or a specific pixel on screen, please explain to me what exactly you need from the LEADTOOLS controls (not the Ink part), and I might be able to help you.
To do that, I recommend you either use one of our demos or create a small test project and give me a detailed description of what you need from that project (such as location of something).
You can either post it here or send it to support@leadtools.com and mention this post.
When attaching to the forums, do not use the "Preview" feature.
Also, please include your attachments in a ZIP or RAR file.

How to get System.Drawing.Rectangle object of the 'image' in screen physical coordinates when zooming or scrolling?

Would you like to show me a quick vb.net code snippet?I'll try if it's what I want.

If what you want is the pixel coordinates of a specific part of the image (such as the client area rectangle), you can convert the coordinates between image pixel units and control client units using the Leadtools.Drawing.Transformer class.
To use this class, you assign the Transform Property of the RasterImageViewer object to the Transformer.Transform Property and then use the RectangleToLogical and RectangleToPhysical methods to do the conversion.
