[Mapserver-users] white (blank) image?

Pedro -

If you take out the projection and have adjusted the EXTENT to be decimal degrees (which is what seems to have been done), then you need to also adjust your UNITS to DD, not METERS.

Subject: [Mapserver-users] white (blank) image?


Greetings, 

I'm trying to view my shapes in mapserver. I defined a simple map file,
but when I invoke my html I'm always getting a blank image!! In "extent"
I put the lower-left point (minx miny) followed by the upper-right point
(maxx maxy). I don't get any error (I think...), but I don't know how
should I debug it!!

By the way, I comment in the PROJ directive (to not interfere).

Any help would be appreciated!

thanks,
Pedro Salazar.
