Opacity Control for Google Maps in official demo gallery
Published Nov 03, 2008 Updated Nov 05, 2008

One of the results of the MapTiler/GDAL2Tiles is an extension of Google Maps API for new functionality related to tile overlays. In summer I created an Opacity slider control for Google Maps which lets the user drag a slider to change the transparency of a TileLayerOverlay on the map.
Recently I was contacted by Pamela Fox from Google and now she add my control to the official Google Maps API Demo Gallery.
I still should add similar control to OpenLayers, but till now there was no time for that unfortunately. The design of the control is finished (done in SVG in Inkscape, same as the Google one), so only the coding in JavaScript is missing. Christopher Schmidt from OpenLayers recommended to create a new OpenLayers Addin.opher Schmidt from OpenLayers recommended to create a new OpenLayers Addin.
