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.
|
|

|
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.
|
|

|
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; it 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 is obtained
|
|
by means of the special value <TT>{nb}</TT> which will be substituted on document closure
|
|
(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.
|
|

|
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 performed
|
|
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>.
