pdf conversion misses images if wiki not on standard port

[anonymous]

PDF conversion was missing images because my web server running Trac is not on a standard port. When I changed the line that is supposed to correct the image links from:

page = re.sub('<img src="(?!\w+://', '<img src="%s://%s' % (req.scheme, req.server_name), page)

to:

page = re.sub('<img src="(?!\w+://', '<img src="%s://%s:%d' % (req.scheme, req.server_name, req.server_port), page)

Then it now works ok for me.

Thanks for a very useful plugin!
