Application w2x-app is intended to be used directly from the directory created by unzipping its distribution.
On Windows, you can start w2x-app by double-clicking
On the Mac and on Linux, please type the following command in a terminal, then press Enter:
/opt$ w2x-1_5_1/bin/w2x-app &
w2x-app works fine on computers having very high resolution (HiDPI) screens. For example, it works fine on a Mac having a Retina® screen and a Windows computer having an UHD (“4K”) screen.
However, on some Linux computers having HiDPI screens, HiDPI is not automatically detected. You'll have to specify the display scaling factor you prefer using the
-putpref command-line option:
w2x-app -putpref displayScaling 200
displayScaling may be used to globally change the size of all the items comprising the user interface of w2x-app. Its value is a percentage between 100 and 400 or integer -1 which means use system settings.
Note that using option
-putpref updates the user preferences file. Therefore suffice to specify
-putpref once and you are done.
 Alternatively, type the following command in a command prompt and then press Enter:
w2x-app-c.bat on Windows , but only when you need to start w2x-app with a console. On Windows, a console is needed to be able to see low-level error messages.
