See if you can find a copy of arial.ttf (debian systems can install them with a package called msttcorefonts, look in /usr/share/fonts/truetype/msttcorefonts/).

Now, put this file in the $PWD of the trac script. If you are using tracd, then this is where you called tracd from. In an FCGI scenario then this is the dir where the fcgi script lives (in my case /var/www/cgi-bin).

Ideally there would be a configurable prefix for the fonts, and probably also let you choose an alternative font.

Sorry, I am using Apache with mod_wsgi, I have arial.ttf but I couldn´t make it work. Do you have any idea where do I have to put arial.ttf?

to solve this do that: open gantt.py and go to:

font = ImageFont?.truetype("arial.ttf", 12)

and add this:

font_path = self.config.get('gantt', 'font_path') font = ImageFont?.truetype(font_path,12)

now in gantt section in yout trac.ini add:

[gantt] cache_dir = /tmp/gantt_cache font_path = /path/to/my/font/arial.ttf

now you can use a custom font in a custom place.
