Hi Brian, > > We're busy preparing for the AMS mountain met conference next month, and > consequently some questions regarding IDV have come up. Some of these > solutions are probably simple, but we haven't found them yet. > > 1. In attempting to print to a postscript file (using the print option > under the display menu), the output is cropped to the selected paper size. > Is there a way to scale the display to fit the page? > To be honest I didn't know you could save to a ps file. You are probably better off capturing the display as an image (.e.g, png) and then bringing it into word, etc., for final formatting. > 2. Can the installed location databases be edited? For example, in the > T-REX plugin the DRI network does not include elevations, which makes it > difficult to display on 3-D topography. If editing is not an option, is > there a way to create a new locations database? > Yes, you can edit it. I am attaching the dri xml file. Just add a elev="elevation in meters" to each entry. Mail this back to me and I will rebuild the jar file if you want. If you have a java jdk installed you can do: jar -xvf trex.jar look for the dri.xml file in: ucar/unidata/apps/trex/data/sensors/dri.xml edit it. then create the new plugin: jar -cvf trex.jar ucar > 3.

At start up the IDV fetches a resource xml file from our web server (port 80). The Thredds data server usually is on port 8080. The ADDE servers are accessed via port 112. > 4. Finally, when I display too many datasets (topography, flight tracks, > and aircraft locations in a map and transect), the program will eventually > freeze and I get a error message such as the one attached. The memory > display indicates that I am under the maximum, so I'm not sure what the > problem would be. > That's a bad error. The JVM core dumped. I get that occasionally on my Linux box. Unfortunately I don't have any solutions to offer. -Jeff Ticket Details =================== Ticket ID: NIB-631217 Department: Support IDV Priority: Normal Status: Closed
