I have downloaded and tested the latest version of Aspose.Words (9.7). I am also using the latest version of Adobe Reader (9.4.2).
I created a simple document with text and a picture and formatted the picture to have different types of wrapping. Here are the results.
Tight Left appears to behave like Square Left
This isn't too bad so...
I then tested a document that we've been having trouble with when converting to PDF (It has a text box that uses 'Square Other' wrapping). It is improved, in that the text box no longer overlaps the normal text. Unfortunately half of the normal text gets pushed onto the 2nd page.
I have attached the word document and the PDF document. I'd be really grateful if someone could tell me why this is happening and how to fix it.
