<h1>Header, footer, page break and image</h1>
Here's a two page example with header, footer and logo:

This example makes use of the <a href='../doc/header.htm'>Header()</a> and <a href='../doc/footer.htm'>Footer()</a> methods to process page headers and
footers. They are called automatically. They already exist in the FPDF class but do nothing,
therefore we have to extend the class and override them.
<br>
<br>
The logo is printed with the <a href='../doc/image.htm'>Image()</a> method by specifying its upper-left corner and
its width. The height is calculated automatically to respect the image proportions.
<br>
<br>
To print the page number, a null value is passed as the cell width. It means that the cell
should extend up to the right margin of the page; this is handy to center text. The current page
number is returned by the <a href='../doc/pageno.htm'>PageNo()</a> method; as for the total number of pages, it's obtained
via the special value <code>{nb}</code> which is substituted when the document is finished
(provided you first called <a href='../doc/aliasnbpages.htm'>AliasNbPages()</a>).
<br>
Note the use of the <a href='../doc/sety.htm'>SetY()</a> method which allows to set position at an absolute location in
the page, starting from the top or the bottom.
<br>
<br>
Another interesting feature is used here: the automatic page breaking. As soon as a cell would
cross a limit in the page (at 2 centimeters from the bottom by default), a break is issued
and the font restored. Although the header and footer select their own font (Arial), the body
continues with Times. This mechanism of automatic restoration also applies to colors and line
width. The limit which triggers page breaks can be set with <a href='../doc/setautopagebreak.htm'>SetAutoPageBreak()</a>.
