24</SCRIPT>
25This 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
26footers. They are called automatically. They already exist in the FPDF class but do nothing,
27therefore we have to extend the class and override them.
28<BR>
29<BR>
30The logo is printed with the <A HREF='../doc/image.htm'>Image()</A> method by specifying its upper-left corner and
31its width. The height is calculated automatically to respect the image proportions.
32<BR>
33<BR>
34To print the page number, a null value is passed as the cell width. It means that the cell
35should extend up to the right margin of the page; it is handy to center text. The current page
36number is returned by the <A HREF='../doc/pageno.htm'>PageNo()</A> method; as for the total number of pages, it is obtained
37by means of the special value <TT>{nb}</TT> which will be substituted on document closure
38(provided you first called <A HREF='../doc/aliasnbpages.htm'>AliasNbPages()</A>).
39<BR>
40Note the use of the <A HREF='../doc/sety.htm'>SetY()</A> method which allows to set position at an absolute location in
41the page, starting from the top or the bottom.
42<BR>
43<BR>
44Another interesting feature is used here: the automatic page breaking. As soon as a cell would
45cross a limit in the page (at 2 centimeters from the bottom by default), a break is performed
46and the font restored. Although the header and footer select their own font (Arial), the body
47continues with Times. This mechanism of automatic restoration also applies to colors and line
48width. The limit which triggers page breaks can be set with <A HREF='../doc/setautopagebreak.htm'>SetAutoPageBreak()</A>.
