I am a new user of MapServer, using version 5.0.3 from the Ubuntu repositories. I attempted to compile everything from source, had some trouble, then decided to use the repository shortcut at least until I understood how the application works.
I am writing an application where the browser requests a map by setting the src attribute of an img object. Identifying locations on the resulting map requires that the application knows the extent. I calculate the extent of the map from various values, and use the same algorithms on the server so the browser and the server agree on the dimensions without having to negotiate. However, when I request the map from MapServer, the extent of the resulting map is always larger (both x and y dimensions) than what I requested, although still centered on the same point. Is this behavior normal (I don't want to beat my head against the wall searching for an irrelevant math error)? Is there some setting that might cause MapServer to more closely match my requested extent? Could this be an error that was fixed in a more recent version of MapServer? Any words of wisdom would be appreciated.
