55 |
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 |
56 |
footers. They are called automatically. They already exist in the FPDF class but do nothing, |
57 |
therefore we have to extend the class and override them. |
58 |
<br>
|
59 |
<br>
|
60 |
The logo is printed with the <a href='../doc/image.htm'>Image()</a> method by specifying its upper-left corner and |
61 |
its width. The height is calculated automatically to respect the image proportions. |
62 |
<br>
|
63 |
<br>
|
64 |
To print the page number, a null value is passed as the cell width. It means that the cell |
65 |
should extend up to the right margin of the page; it is handy to center text. The current page |
66 |
number is returned by the <a href='../doc/pageno.htm'>PageNo()</a> method; as for the total number of pages, it is obtained |
67 |
by means of the special value <code>{nb}</code> which will be substituted on document closure |
68 |
(provided you first called <a href='../doc/aliasnbpages.htm'>AliasNbPages()</a>). |
69 |
<br>
|
70 |
Note the use of the <a href='../doc/sety.htm'>SetY()</a> method which allows to set position at an absolute location in |
71 |
the page, starting from the top or the bottom. |
72 |
<br>
|
73 |
<br>
|
74 |
Another interesting feature is used here: the automatic page breaking. As soon as a cell would |
75 |
cross a limit in the page (at 2 centimeters from the bottom by default), a break is performed |
76 |
and the font restored. Although the header and footer select their own font (Arial), the body |
77 |
continues with Times. This mechanism of automatic restoration also applies to colors and line |
78 |
width. The limit which triggers page breaks can be set with <a href='../doc/setautopagebreak.htm'>SetAutoPageBreak()</a>. |
