Your issues are related to invalid input document and to incorrect using of PdfSaveOptions:

  1. Alternate text: the issue is caused by the images/shapes that does not have the alt text. To fix it, you can open the document in MS Word and check for Accessibility. validation.jpg (251.7 KB)
  2. All content should have the alt text or be marked as decorative (support for this feature will be added in the May release Aspose.Words 21.5).
  3. Pdf logic structure: to export the logical structure of the document needs to use a PdfSaveOptions:
PdfSaveOptions so = new PdfSaveOptions(); 
Document doc = new Document(path); 
so.OutlineOptions.HeadingsOutlineLevels = 5; 
so.DisplayDocTitle = true; 
so.ExportDocumentStructure = true; 
doc.Save(outPath, so);
  1. The issue with invalid table headers is already known and was logged with issue ID WORDSNET-21795. It is a missing feature in Aspose.Words. We will inform you via this forum thread once this feature is available.

A post was split to a new topic: Support of decorative shapes for document accessibility

The issues you have found earlier (filed as WORDSNET-22083) have been fixed in this Aspose.Words for .NET 21.7 update and this Aspose.Words for Java 21.7 update.
