Set annotation link target to PDF attachment

[Halla602]

Hi, I am unable to solve this C# problem with annotation and attachment.

I currently have a file that was generated elsewhere from HTML into PDF, which I am editing using GDPicutre.
I save the files that were referenced in HTML localy and then I embed into PDF.
My problem is, the original HTMl links are (in the newly created PDF file) converted to annotations.
By using this code, I am able to read the ActionURI (which is set to local files by my other HTML -> PDF SDK when the conversion from HTML link to local files occurs) using this code:

Code: Select all

 string[] Files = Directory.GetFiles(Temp_Attachements_Dir);
 for (int i = 0; i < Files.Length; i++)
 {
   Output_PDF.EmbedFile(Files[i], Path.GetFileName(Files[i]), "");              
 }
 count = Output_PDF.GetAnnotationCount();
 for (int i = 0; i < count; i++)
 {
   Output_PDF.GetActionURI(Output_PDF.GetAnnotationActionID(i));
 }

The last call returns value, whic points at the local file, such as "C:\Windows\Temp\Local_Attachment.jpg" -> which is the same file, that I embed in the for{} cycle before.

Is there any way to change this Annotation to point at the file I embeded into PDF and not at the local file, so when I click the link in the PDF (opened in acrobat for example), it opens the attachment / opens the attachment tab ?
I attached a sample PDF file showing my problem (it references local paths, but also has the same files as attachments).

Hi,

the second example here shows you the approach that can be useful:
