Hi, I have a scenario wherein we are utilizing Leadtools.Windows.Annotations.AnnObjectBase for image annotation under (v16.5) . Then we updated our Leadtools version to 19 my problem is the AnnObjectBase is no longer found on latest version 19. Does anyone know where can I found it? Or are there any work around. It's look like they removed it completely on latest version.[img=https://www.screencast.com/t/83zCR8qbyjh]AnnObjectBase[/img]

Hello Carlo,

I believe all of our more recent annotations (at least back to v18) we use AnnObject as the base class for all the annotations. In the screenshot I see you were using that class for custom annotations. If you'd like to see how to create custom annotations for v19 we have a blog post with a sample project you can refer to:
https://www.leadtools.com/blog/document-imaging/custom-annotations-25-projects-25-days/

Also, we have some information about custom annotations in our documentation:
https://www.leadtools.com/help/leadtools/v19/dh/to/ac-topics-implementinguserdefinedobjectswithleadtoolsannotationsinwindowsforms.html

I'm assuming you have just started with your conversion to v19, if this is the case, I strongly recommend you use the Leadtools.Annotations.Core assembly, rather than the deprecated Leadtools.Annotations assembly. This will allow your application to be converting to a newer version more easily if you ever decide to upgrade again in the future.

Thanks,
