xshow [-f ffconfigfile]

Description

xshow is a handy graphical user interface(GUI) that shows a low resolution map. xshow can be used to view single images, much like xv. xshow can also be used with ff to help get a general idea of direction and location. Under the View menu, there are two options, the Show Key Frames Toggle or the Show Flight Path Toggle. The key frames toggle shows only the location of the viewpoints visited, the flight path toggle connects all the viewpoints together with straight line segments. The Clear All option will clear all the key frames. The map changes size according to the xshow window size. A sequence of maps can be saved by clicking on the File Save option and specifying location and filename prefix. Maps will be saved with the name prefix######.

Options

-r resourcename
            Specify the resource name of the Router where it receives viewpoints from.
-s
            Specify the image is a global image and the viewpoints received are in Cartesian 3D coordinate.
-f ffconfigfile
            Take Flexible Flyer's configuration file as the input argument. The first surface defined in the config file will be              loaded into xshow. The Router resource name defined in the config file will be used as well.
