Hi Cindy. First off, we have a few questions. Can you tell us more about what institution or company you work for? I have a few more comments below: > Hi. > I have two questions using idv and need your big help. > All the situation appears in Java enviroment using jdk1.6.0_20. > > Question1: I download IDV 2.9u2 Installer for Windows XP from your website. > An error occures when opertating as follow steps: > > (1) Start idv 2.9u2. > (2) > In default mapView , I create two drawingControls using tools from > toolbar :control1 and control2, So control1 is firstly created. > (3) Open each drawing control window, add a text shape to each control .

Error occurs as below: > " visad.DisplayException: ScalarMap.setDisplay: ScalarMap cannot belong to > two Displays " I can confirm the errors that you see. Unfortunately, we do not have any quick resolutions to offer. Is there a way to achieve what you want without going through multiple display controls and map views? You may be able to find a work around through experimentation. > Such > error can also be seen in the other version.

If you want to capture a very large image you can save the state (File->Save) as an .isl file, e.g., test.isl. The IDV will prompt you for some of the parameters to the ISL script including image size. Choose offscreen rendering and specify a larger image size.
