On my map, if you right click on a layer in the right hand legend, then you get a context menu which includes an opacity slider where appropriate. For example of overlaid raster, see the the Frontier map, look at gravity or magnetic overlain on google. Implementation is tricky. I am using a context menu plugin to the tree, then using geoext's opacity slider implementation. At a pure OL level, opacity is part of the wms layer properties so straightforward to impl I wait with anxious your precious suggestions to the Peter's questions too. Hmm, I didnt see further questions from Peter? Notice: This email and any attachments are confidential. If received in error please destroy and immediately notify us.
