Are you after the middle WGS points or the middle points on a mercator grid
The 2 points must be converted to mercator.

Hi all
Maybe that one is easy for someone out there, for me it's unsolvable.
I have
minlat, minlon, maxlat, maxlon
That describes an area in WGS84
The area should be placed on the screen.
To place it on the screen, I need the centerlat,centerlng and the zoomlevel.
To be shorter on that:
How about converting to UTM then using a zoom level specified as meters
per pixel?
Here is what I did when printing from Mapnik:

Hint:
At first you maybe think
centerLat = (minlat + matlat)/2;
centerLng = (minlng + matlng)/2;
could be the solution.
But that does not give the correct
Small correction:
I think your problem is more fundamental; because min and max are not
going to work ;) lefttop, righttop, leftbottom, right bottom are.
Good Point you are right on that.
I have 2 Points in WGS84:
Southeast (example 0,0)
Northwest (example 90, 180)
