[IDV #IMF-703813]: imageserver

["Unidata IDV Support" <support-idv@xxxxxxxxxxxxxxxx>]

Hi Reinoud,

> I am testing the -imageserver option of IDV to see if I can use it as a backend (i.e. map drawing engine) for our WMS server (Mapserver). The idea is that I would translate a WMS request to either a bundle file or ISL script and to submit that to the imageserver.

The imageserver facility is something we started in on some years ago but never finished. However, server based generation of imagery is something we are starting to work on this summer. We are in need of users who can help us figure out the requirements, etc. Would you be willing to be involved in this effort?

One thing we are doing is providing support for the IDV to be used within a Java-based server environment (e.g., Tomcat) instead of the standalone imageserver approach. Do you run under Tomcat or does the imageserver based approach work best in your environment?

As to the imageserver right now - you do need to supply a bundle= argument. The IDV will load up the bundle and capture an image or a movie. I am adding some quick fixes right now so that the IDV runs in offscreen mode (like in the ISL context) and that you can specify width and height http arguments for the image size. The projection is defined within the bundle itself though that can be something we can look at supporting through external arguments.



Thanks,
Jeff
