Printing pop-up annotations

Post by IntegraHarlan »

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 Harlan,

PDF popup annotation does not have appearance but it has information about rectangle on PDF page, where popup annotation must be drawn. Appearance of PDF popup annotation depends from PDF reader application that displays PDF document. Our PDF Editor Demo uses WinForms user controls for displaying popup annotations.

Do you want to print PDF document with WinForms user controls?

Best regards, Alexander

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

Thanks

Hi Harlan,

We created example for your task but example needs functionality, which is not present in current version. Necessary functionality will be available in next minor version, which will be released next week. After version release we will provide example for your task.

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.

Source codes of CommentedPdfPrintDocument class:

Code: Select all

using System.Collections.Generic;

using System.Windows.Forms;

using Vintasoft.Imaging;
using Vintasoft.Imaging.Annotation.UI.Comments;

using Vintasoft.Imaging.Pdf.Print;
using Vintasoft.Imaging.Utils;
