And the handler was called using the line....

http://www.thierrybazzanella.com/wakka.php?wiki=Accueil/raw&pdf=1∞

and here are the instructions....

"Elle est téléchargeable vers http://www.fpdf.org∞

INSTALLATION:

Téléchargez la librairie fpdf et dézippez-là dans un dossier.
Mettez le fichier fpdf.php et le dossier font à la racine de votre wiki.
Téléchargez le fichier handlers/page/raw.php livré ICI,éditez le, et définissez en absolu le chemin du dossier font de votre arborescence fichier.
Ligne 25 : define('FPDF_FONTPATH','/home/www/users/thierrybazzanella/www/html/font/');

Remplacer ce fichier par le vôtre en lieu et place. "

that were there.

Thanks, Mike. That looks nicely implemented - though I don't see where the page is turned into HTML first; my guess is you need to run it through the formatter first (it looks like it's transforming HTML tags - not Wiki-markup tags - for printing as PDF). But it shouldn't be too hard to make it work. --JavaWoman

Installing Fpdf

1. download the fpdf-package and put it's content into 3rdparty/plugins/fpdf
2. save the following code as handlers/page/pdf.php
