1.3.3 Using the GUI launcher

The graphical interface for the applications provides a usefull interactive user interface to set the parameters, choose files, and monitor the execution progress.

This interface can be activated through the CMake option OTB_WRAP_QT.

This launcher needs the same two arguments as the command line launcher :

$ otbApplicationLauncherQt module_name [MODULEPATH]

The application paths can be set with the OTB_APPLICATION_PATH environment variable, as for the command line launcher. Also, as for the command-line application, a more simple script is generated and installed by OTB to ease the configuration of the module path : to launch the Rescale graphical user interface, one will start the otbgui_Rescale script.

The resulting graphical application displays a window with several tabs:

In this interface, every optional parameter has a check box that you have to tick if you want to set a value and use this parameter. The mandatory parameters cannot be unchecked.

The interface of the application Rescale is shown here as an example.
