see attached sample: it opens a docx file which has a image shape and some text in the header section.
The sample just opens the file using latest Aspose.Words 18.9, and saves it to DOCX and PDF.
In the resulting PDF file the layout is broken: the header text is on the same line as the image.
Thanks for your inquiry. We have tested the scenario and have managed to reproduce the same issue at our side. For the sake of correction, we have logged this problem in our issue tracking system as WORDSNET-17485. You will be notified via this forum thread once this issue is resolved.
The attachment link to my initial post does not work anymore (“Page not found”), so I actually cannot check whether the issue still happens with recent versions.
