Using: ArcGIS API for Flex 2.5 Flash Builder 4.6 Browser: IE and Firefox
var mapImage:MapImage = new MapImage(); var mapImageExtent:Extent = new Extent(Number(externalLayer.xmin), Number(externalLayer.ymin), Number(externalLayer.xmax), Number(externalLayer.ymax), map.spatialReference); mapImage.extent=mapImageExtent; mapImage.href = externalLayer.url; mapImageLayer.add(mapImage);
Everything works great when the Image is added to the map. However when you move the map or zoom the image size changes. The upper left corner is where it is suppose to be but the other 3 corners shift closer to the upper left and stay that way.
