Opacity of base maps

(1/2) > >>

mapcat:

How possible would it be to make the opacity of the base maps user-controlled? For example, the US Census Bureau's TIGERWeb features an opacity slider on its maps.

(expand any category in the layers menu to see it)

Jim:
Do you mean the background map tiles?  If so, only if Google's API has that level of control, I think.

That's right. Thanks.

Somewhat relevant: I submitted a pull request that implements a blank map layer as described in this issue.

After playing around with Chrome's JS console, google does have functions for setting opacity for defined map types: map.mapTypes.Mapnik.setOpacity(0.5) for example.
I have only been able to get it to work with the MQOpenMap, MQOpenSat, and Mapnik layers. For whatever reason this doesn't work on google's built-in layers.

Thanks, I hope to get this and the other items that have been submitted tested out and (if all seems OK) live on the site in the next few days.
