There seems to be an issue in converting Word documents to Tiff - even when we set all sections of a document PageSetup.PaperSize = to PaperSize.A4 the generated tiff doesn’t conform to A4 paper size dimensions - it seems to work on some documents and not on others.
Thanks for your inquiry. Please call the Document.UpdatePageLayout method before saving the document to TIFF file format. Hope this helps you.
