[OSM-talk] #AttributionIsNotOptional experiment on OSM France tile servers

[Mario Frasca]

well, it does look slightly invasive … I had imagined something like a 
transparent text on top of the requested tile.  doing it the way you are 
doing it, you are removing part of the underlying information.  it is 
true that the user can zoom in or out, and the chance that the same are 
is also hidden is, as you state, 4%, but still. … did you experiment 
with a transparency added on top of the requested tile?  that's how I 
would probably do it, and I would only use the lower text, not the top 
icon and bold text, using a smooth opaque mask to make sure the text 
stays well visible, separated from the background.

in practice, I would only add what they need to add themselves, and not 
remove anything.
