[Mapserver-users] perl mapscript dying "Invalid image extent"

[Lowell Filak]

>From what I can quickly grab from the source code it appears that in your map extent either your minimum & maximum x are the same or your minimum & maximum y are the same or both of the previous are true.
If you print $map->{extent}->{minx} & etc. before the draw or temporarily comment out the draw what is shown as the values for the minx, maxx, & etc?
