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##

3. Change the following thing in ##wikka.php##
a) no computing time (i.e. after line 385 if you are using 1.1.6.5):
**change**
%%(php)
if (!preg_match("/(xml|raw|mm)$/", $method))
%%
to
%%(php)
if (!preg_match("/(xml|raw|mm|pdf)$/", $method))
%%


b) we want no header and footer, therefore change in ##libs/Wakka.class.php##
**add** after the following code (i.e. after line 1750 if you are using 1.1.6.5)
%%(php)
		// raw page handler
		elseif ($this->method == "raw")
		{
			header("Content-type: text/plain");
			print($this->Method($this->method));
		}
%%
%%(php)
		//page to pdf - handler
		elseif ($this->method == "pdf")
		{
			print($this->Method($this->method));
		}
%%

4. Notice that the real work has only begun ;)
