Hi all, we just started using OpenLayers as an alternative to googlemaps for a web application we are making. This application is used for comparing two sets of gridded data and displaying the result visually.<br><br>So, my questions:
<br>1. Is there a way to set the Bbox for a WMS.Untiled layer? As far as I can tell the entire world is always queried. Some of our sets use only North American data and loading the entire world takes too long. If this takes writing my own
WMS.custom layer, that's fine, but even looking at the custom WMS classes I just can't find where the max Bbox is set.<br><br>2. Adding an overlay: Is it possible to set the overlay transparent? In my WMS request url, if I had the transparent=true flag, most of the image comes back black but it is still not transparent at all. The black totally covers up the baseLayer.
<br><br><br>If anyone has any questions about what I'm asking, I will respond ASAP.<br>Any suggestions at all are greatly appreciated.<br><br>Thanks in advance!<br>-Ed <br><br><br>
