[mapguide-users] [mapguide-announce] MapGuide Open Source 2.0.0released

[Kenneth Skovhede, GEOGRAF A/S]

You can change this in the file "ajaxmappane.templ".
Around line 1666 you will find:

function RequestMapImage(reqId)
{
    url = webAgent + 
"?OPERATION=GETDYNAMICMAPOVERLAYIMAGE&FORMAT=PNG&VERSION=1.0.0&SESSION=" 
+ sessionId + "&MAPNAME=" + encodeComponent(mapName) + "&SEQ=" + 
Math.random()
    document.getElementById("overlay").innerHTML =
            '<img class="mapImage" name="' + reqId + '" id="mapImage" 
src="' + url + '" width=' + mapDevW + ' height=' + mapDevH + ' border=0 
vspace=0 hspace=0 style="visibility: hidden; width: ' + mapDevW + 'px; 
height: ' + mapDevH + 'px;" onload="return 
OnMapOverlayImageLoaded(event)">';
}

Modify the "FORMAT=PNG" part to your liking. If you need multiple 
formats, you could introduce a variable that the application sets.
