It seems like MGE 2011 in our setup (MGE 2011 Service Pack 1, Windows 2008 64-bit.) cannot produce or create raster in jpeg-format. This affects both the save map function as well as wms.
When trying to save map as jpeg (out-of-the-box widget) a dialog-window say "Preparing Image for download..." but nothing happens. When choosing a different format lika png, gif och dwf it works fine and you get asked to save or show the file.
Unfortunately this problem also appear when asking for jpeg in a WMS request. This is a far more critical problem for us.
It seems like Autodesk provides MGE with it´s own raster FDO which means that following MGOS on this issue is not a solution (correct me if wrong).
Please help!
