||
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>. |
