VintaSoft PDF .NET Plug-in Discussions

Hi,
I am trying to print popup annotations.
There appear to be two annotations that make up the popup annotation.
A PdfTextAnnotation and a PdfPopupAnnotation.
When I print the pdf file, only the text annotation is printed.
I would like to be able to print the PdfPopupAnnotation when it is open on the pdf file.
We are using the Winforms version of the .Net Plug-in.

Thanks
Harlan

Hi Alexander,
Printing the PDF document with WinForms user controls might work.
Do you have an example of this?

Thanks
Harlan

Hi Harlan,

In version 9.0.0.15 we have added the CommentVisualTool.GetCommentControlsByImage method and this allows to create simple example that shows how to print PDF document with WinForms comment controls. Please use the CommentedPdfPrintDocument class (code can be found below) for printing PDF document with WinForms comment controls and let me know if you will have any question or problem.
