[dokuwiki] Re: pdf export

Hi Heikko,
I tried here to fiddle about with this code,

for a start the script "destination.prodownload.class.php"
doesn't seem to be present. I only found
"destination.download.class.php".

I seem to have got it all running with the folowing configuration in the
config file:

// Path to Ghostscript executable
define('GS_PATH','/usr/bin/gs');

// Path to font metric files (AFM files). 
// NOTE: Trailing backslash required
define('TYPE1_FONTS_REPOSITORY',"/usr/share/fonts/type1/gsfonts/");


However it only returned a blank pdf page.
