[mapguide-users] capturing map image

[Andy Morsell]

The pushpin you are talking about is created as part of a users session,
right?  If so, then, yes, you would need to use the session to retrieve the
map if you want to view it.  If you need to do this with no user
interaction, then you should be able to perform all of the steps
programmatically, but you will need to establish a session as part of that
programming.

Hi andy,

i got one question, is that possible to set the push pin image location at
the same time while you get the map image?because if i didn't use the
session parameter, i can't view the push pin on the specific area.
pardon me if my explanation/english is bad.
I hope you can help me out..thank you

regards,
Kencana
