How to reach a comment inside the pdf file?

[mawe1965]

A pdf document can contain multiple comments. These are placed in a page and shown as yellow balloons. A comment can contain an attachment and these are shown as small paperclips.

Does anyone know if there is a object available in the library to access these objects?

Best regards,

Hi there, this sounds like annotations https://github.com/UglyToad/PdfPig#annotations-005

The embedded files will probably be accessible separately through the EmbeddedFiles API https://github.com/UglyToad/PdfPig#annotations-005

Let me know if this works :)

` Dim files As IReadOnlyList(Of EmbeddedFile) = Nothing

            If document.Advanced.TryGetEmbeddedFiles(files) AndAlso files.Count > 0 Then
                For Each EmbeddedFile In files
                    Dim Filename As String = System.IO.Path.GetFileName(EmbeddedFile.FileSpecification)
                    Dim FileExtension As String = System.IO.Path.GetExtension(EmbeddedFile.FileSpecification)

... other code here

                Next
            End If`

this only catches files stored in the attachment tab of the file, not the ones stored in a page.

Here the two different ways the files can be included in the PDF file:

I noticed I can find some info about the excel file from the annotation object. But how to get the excel file extracted is unknown to me.

Are you able to share the file or an example file at all please? There are many many things in the PDF spec so it's hard to know exactly which feature this is without access to the raw file.

I am not able to share the files, they are all classified. If possible I will try to create one myself.
