<p>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.</p>

<div>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%).</div>

<div dir="ltr">I have a bunch of polygons that represent 8.5 x 11 printed map sheets. I'd like to produce images for each sheet that best fits the polygon within the outputted image. We've tried using mapscript by setting the map extent based on the bbox
of the source polygon and rotation but results aren't great depending on the orientation of the source polygon. Is there a way to set the "extent" based on a polygon? </div>
