In the Atlantis Word Processor documents, headers and footers are a special layer of content located behind the document's main layer. When the content of the two layers overlap, the latter always prevails (i.e. the document's main content displays over the header's content).
Since the headers are always "behind", they can be used to add various backgrounds to the document pages. But that is not the only way to affect the document's main area with headers. Floating pictures in headers can also be used to adjust the content flow in the document's main layer. When a header contains a picture with the "Square", "Tight" or "Through" text wrapping style, and that picture is overlapped by the document's main area, the document main text would respect the wrapping style of the header's picture (i.e. would flow around it).
Let's take an example:
