<DIV>imgext is an input parameter as far as I know. If I know it, then I use imgext to request the map with that particular extent. But in my case I only know the center point (geocoded address), the scale and the image width/height. These are my inputs. Mapserver calculates the extent when drawing the map. How can I ask Mapserver to return this extent (coordinates of bottom-right and top-left of the map) besides returning the rendered image?</DIV>
<DIV> </DIV>
<DIV>So my input is: center lat/lon; scale; width/height pixels of map</DIV>
<DIV>Current output: 1) image</DIV>
<DIV> </DIV>
<DIV>Desired output: 1) image and 2) bottom-right/top-left coordinates</DIV>
