Does the map print with the watermark or is it only for screen viewing? Andy

The expected parameters to this JavaScript method are: doc: The document object, such as that returned by "frames['mapFrame'].document" imageUrl: The path to the watermark tile, e.g. "/images/watermark.gif" So this method will insert a DIV that covers the entire map with the tiled image. My image is transparent except for the required watermark string. In the code I set the opacity, but this is probably not necessary if you get your image looking the way you want it to beforehand. There are two important things to note: 1. I'm using this in a WebLayout with no left or right pane, and the middle pane comprises the status bar and zoom control only (plus the map of course). In this configuration the map frame is resizeable despite no left pane being present, which is undesirable. Fortunately, the watermarking method below covers this up and prevents manual resizing. 2. The z-index of the inserted DIV must be configured to be less than that of the zoom control ("scale slider") so that it appears underneath, but still above the map image. ShowInAjaxViewer: function(doc, imageUrl) { if (!doc) return; if (!imageUrl) return; // // Create a DIV to hold the watermark. // var watermark = doc.createElement('div'); // // Assign the passed-in background image URL. // watermark.style.backgroundImage = 'url(' + imageUrl + ')'; // // This value is very important. It must be less than the lowest z-index // value used by the scale slider (which happens to be 4 at the time of // writing. // watermark.style.zIndex = '3'; // // The rest of the styles. // watermark.style.position = 'absolute'; watermark.style.width = '100%'; watermark.style.height = '100%'; watermark.style.opacity = 0.5; watermark.style.filter = 'alpha(opacity=50)'; doc.body.insertBefore(watermark, doc.body.firstChild); } Hope this helps somebody.
