| 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>.
