[postgis-users] Problem with ellipse function

[franco califano]

Hi.
I tried to use the ellipse function in
http://postgis.refractions.net/support/wiki/index.php?plpgsqlfunctions

but i find a problem.
The shape of ellipse depends on the latitude of the center point (the ry variable).
The bigger is it, the more the ellipse is stretched.
How can i solve this problem?
Thanks a lot.
