We have an issue with converting a doc/docx file to a pdf, and maintaining all accessibility information for the document. We have used the following code-snippet to ensure that structured content is copied to the destination pdf:
using (Stream tempStream = File.Create(tempFile.FullName))
{
PdfSaveOptions options = new PdfSaveOptions();
options.ExportDocumentStructure = true;
options.DisplayDocTitle = true;
options.PreserveFormFields = true;
m_Document.Save(tempStream, options);
}
When doing this action, the resulting pdf retains all tagged/ordered content from the word document in terms of the text content. However, when you insert an image to the word document, and give the image an alt-text property, the document does not retain the image as tagged content, and does not copy over the alt-text of the image/table properly, resulting in the failure of multiple conditions on an accessibility check in adobe acrobat.

Are there additional parameters needed in the save options to get the images to be processed properly?
