Description

This extension adds bookmark support. The method to add a bookmark is:

Bookmark(string txt [, boolean isUTF8 [, int level [, float y]]])

txt: the bookmark title.
isUTF8: indicates if the title is encoded in ISO-8859-1 (false) or UTF-8 (true>). Default value: false.
level: the bookmark level (0 is top level, 1 is just below, and so on). Default value: 0.
y: the y position of the bookmark destination in the current page. -1 means the current position. Default value: 0.

Example

<?php require('bookmark.php'); $pdf = new PDF_Bookmark(); $pdf->SetFont('Arial', '', 15); // Page 1 $pdf->AddPage(); $pdf->Bookmark('Page 1', false); $pdf->Bookmark('Paragraph 1', false, 1, -1); $pdf->Cell(0, 6, 'Paragraph 1'); $pdf->Ln(50); $pdf->Bookmark('Paragraph 2', false, 1, -1); $pdf->Cell(0, 6, 'Paragraph 2'); // Page 2 $pdf->AddPage(); $pdf->Bookmark('Page 2', false); $pdf->Bookmark('Paragraph 3', false, 1, -1); $pdf->Cell(0, 6, 'Paragraph 3'); $pdf->Output(); ?>
