Some quick, poorly researched responses which hopefully should give you a jump start.

Printing is tricky in web browers, especially with when displaying many layers as happens in Mapbuilder. From memory, the [print] from firefox works, but from IE 6 you don't get all layers. There has been much discussion about this over the years which you can find by trawling through mapbuilder-devel archives. From memory, the best solutions have an element of server side solution. If all your layers come from the same WMS, you are lucky because you can build an image with all layers merged into one. I'm a bit out of touch on this, so I suggest getting a second opinion. Pinging the openlayers list would be a good start. > > Problem 2 is that we have been using Ka-Map to tile and display the > tiles becuase some of the data sets are large and can take a long time > to load.

Mapbuilder wraps Openlayers, so any configuration param in Openlayers should be configurable from Mapubilder. It sounds likely that you would need to create a new Layer type to put into the OWS Context type and provide support for that in MapPane2.js So I suspect it is possible, but you will probably need to do some JS coding. > > Problem 3 is that I have gotten a tree structure going with the layers > and vectors, but the layers that won't display till a lower resolution > keep showing up in that list. Is there anyway to hide the layers that > won't be displayed on the map for that resolution? OWSContext and WMC allow you to specify a Max/Min scale value. What you could do is extend Legend.js (or Legend.xsl) to recognise the Max/Min scales and only display layers in scale. This should be set up to be configurable and would be a nice Mapbuilder addition. Again, some JS and/or XSLT programming required here. > > Thank you for taking the time to look at these questions and I look > forward to your response. > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------- > This SF.net email is sponsored by the 2008 JavaOne(SM) Conference > Don't miss this year's exciting event.
