Editing the accessibility tagging of an existing PDF

[Iddo Weis]

I'm trying to edit the accessibility tagging of an existing pdf using the examples in https://help.syncfusion.com/file-formats/pdf/working-with-tagged-pdf, but the document's tags don't seem to change. I can add elements to the pdf's content, but nothing changes in the tag tree when viewing in Adobe Acrobat.

Am I missing something here, or is this not possible? I know you can create a new tagged PDF, but not edit one?

Thank you,

My code:

PdfLoadedDocument document = new PdfLoadedDocument(fileName);

PdfStructureElement rootElement = document.StructureElement;

rootElement.TagType = PdfTagType.HeadingLevel1;

foreach (var child1 in rootElement.ChildElements)

{

child1.TagType = PdfTagType.HeadingLevel1;

child1.AlternateText = "test";

child1.ActualText = "test";

}

document.Save(newFileName);

document.Close(true);
