@rabinintig The shapes that goes out of the left edge have negative horizontal position. In the source MS Word document they goes outsize left page margin too. So in this case you have encountered the expected behavior. By the way MS Word also shifts the shapes outsized the visible area if save your document to HTML.
If you need to preserve MS Word document layout in HTML, you can try using
SaveFormat.HTML_FIXED. In this case, Aspose.Words produces HTML with fixed position of all elements and the output document looks exactly the same as if you save it to PDF or XPS:
Document doc = new Document("C:\\Temp\\in.docx");
