I would just to have like to take the HTML to PDF result, and then auto-tag it - because at the moment since there is no tagged content, I can’t do anything about programmatically tagging those elements.
It is similar to convert the PDF result into tagged PDF and we have tried that already. We tried to convert the document directly into PDF/UA but image was not tagged in the output for alternate text. We then tried to tag the images by accessing ITaggedContent but API did not find any StructureElement in the PDF.
HtmlLoadOptions htmlLoadOptions = new HtmlLoadOptions();
htmlLoadOptions.PageInfo.Width = Aspose.Pdf.PageSize.PageLegal.Width;
htmlLoadOptions.PageInfo.Height = Aspose.Pdf.PageSize.PageLegal.Height;
htmlLoadOptions.PageInfo.Margin = new MarginInfo(0, 48, 0, 36);
Document doc = new Document(dataDir + "testing_data.html", htmlLoadOptions);
doc.Convert(dataDir + "validationlog.xml", PdfFormat.PDF_UA_1, ConvertErrorAction.Delete);
doc.Save(dataDir + "pdf209.pdf");
doc = new Document(dataDir + "pdf209.pdf");
ITaggedContent taggedContent = doc.TaggedContent;
StructureElement rootElement = taggedContent.RootElement;
// Set title for tagged pdf document
taggedContent.SetTitle("Document with images");
foreach (FigureElement figureElement in rootElement.FindElements<FigureElement>(true))
{
// Set Alternative Text for Figure
figureElement.AlternativeText = "Figure alternative text (technique 2)";
}
doc.Save(dataDir + "taggedimage.pdf");

Right I know the image element could not be tagged - however this is also true for the rest of the elements correct, that there is no way to tag any of the elements that are existing there already via the HTML to PDF approach I provided examples of?
