Hi Crispin
We need to do the same thing. I had thought of creating a polygon object to cover the whole region, adding the watermark as a feature label, style the layer with no fill and no edge etc. One limitation is you can only use text and the watermark location is always central, but it does mean the polygon layer can be at the botton on the display list with the label at the top. This is similar to your option 4. In the past with MG6.5 we have used the onViewChanged to update a redline watermark, I'm sure a similar approach would work here.

Not in Fusion, just on a basic layout. A common situation is to have to add either a copyright notice or other watermarking/branding to mapping. Within the MapGuide environment I have come up with some options - discussion and suggestions welcome... 1) Open all the raster imagery and watermark it! Bit brutal and also does not account for different scales of mapping based on the same source or provide ability to always put a copyright notice down in one corner. 2) Use a low-level WWW service (IIS on Windows) process to intercept the image and edit before sending it out. This is "easy" on IIS7/Win2008 apparently due to a new API but I can't get it to happen on lower versions properly - I watermark the top of the image and truncate the rest. Plus this is a Windows only solution could do better: 3) Add an additional tiled-layer of a standard image overlay. Create a complete tile-cache and then replace every tile in the cache with a transparent watermark image and have that as an overlay to both vector and raster data. Can you seed a tile cache tree. This has the advantage that is would work for vector as well as raster data but is a bit of a sledgehammer and also cannot put a notice just on one corner of the map. 4) Edit the .templ files to include an additional layer that is turned on and off somehow according to scale. The would need to be on top of the map and possibly mess up the mouse interaction but has lots of inherent advantages in positioning, style, network and server efficiency. 5) Add to the MapGuide server functionality the ability to have a scale-dependant overlay image 'layer'. This layer, defined by a static image could be cantered, stretched, tiled, or placed in one of the four corners of the map. This is then built into the final image rendered by the server and is almost essential functionality IMHO. -- View this message in context: http://www.nabble.com/Watermarking-a-Map-tp19457144p19457144.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
