I use Ubuntu Server Feisty, Trac 0.10.3 and Dia version 0.96.1. Once I installed DiaViewPlugin and modified the TODO for the dia path my pages with dia attachments and Macro usage would only show the HTML image tag "alt" attribute text:
JPG render of a DIA file.
In my trac.log file I would get the following:
2007-07-11 19:15:06,947 Trac[DiaView] INFO: New attachment: TracTest.png

I decided to try the dia command from the command line and it failed as follows:
bram@pyfool:/home/trac/qcard/plugins$ /usr/bin/dia -l --export-to-format=png --export=/home/trac/qcard/attachments/wiki/QcardAgi/TracTest.png /home/trac/qcard/attachments/wiki/QcardAgi/TracTest.dia
Unknown option --export-to-format=png
This prompted me to /usr/bin/dia --help which pointed out an option change to replace
--export-to-format=png
with
--filter=png
After making this change things worked perfectly...well as far as I have tested. Maybe some type of dia version testing should be done to determine exactly which options should be used for the export.
Thanks for the great plugin!
