Re: Possible bug in EPS export for Network Miditower object? (fwd)

[Andrew Ferrier <andrew junk new-destiny co uk>]

Further to that discussion yesterday, I tried creating a
diagram where all the line widths were 0.01 and that seemed to
fix the problem --- all lines are now thin when rendered in
EPS. So that seems to be a good workaround. The inconsistent
behaviour is still something which should stay on the buglist
though IMHO. Also maybe the 'special case' test which you cited
yesterday should be changed to a thinner line? Maybe 0.01 for
example?

If you say so :) That certainly sounds like the right kind of
thing.

OK, fine. I wouldn't want to encourage dia making non-standard
EPS files. I'll switch over to 0.01 and see if that fixes my
problem.

Yes, definitely. I don't know why it's happening but the end
result is definitely that different objects get exported with
patently different line widths --- whatever the boundary
condition mapping, as you showed above, it's not being applied
consistently.
