Re: [mapserver-users] rotate and fit based on polygon

[Lime, Steve D (MNIT)]

Looks like you need to use the polygon extent to compute the rotation angle but 
then should use the extent of the rotated polygon for the map extent.

Thanks Carlos, we've employed the method you've suggested already but not 
getting the results we are looking for, perhaps the linked image will help 
illustrate my problem

Travis,

Do you have the polygons in PostGIS ? Maybe you can get the extent by using 
st_extent(geom) and retrieve it on PHP/Python to set the map extent. You could 
also get a margin by multiplying extent b 1.1 (10%).

It’s kinda hard to picture what you’re after, any way to help visualize it?
