[mapserver-users] Repeating annotation, using LABEL_NO_CLIP=1 with Open Layers

[Lime, Steve D (DNR)]

Do you have to have them in the image or is it enough to have them displayed some other way? Work arounds include:

  - Use untiled with 'ratio:1', creates images the same size as your view port.
  - Just drop the copyright in a div over the top of the viewport and don't have it in the image.
  - Could even create a copyright only layer in OL but if that's the only use then I'd just use the browser to do it.

It probably still there, only out of frame if you are using OpenLayers, 
which I believe grabs a tile larger than the current view for panning by 
the user.

Other than adding another layer or restricting the tiles retrieved to 
the same size as the current view port, I don't know of a way of getting 
a copyright into view.  There may be some OpenLayers settings that aloow 
for a center tile that is as large as the current view with tiles 
arouand the edges, but this may be a performance hit.
