The splash screen is displayed at Mobile Authenticator Studio startup. It disappears as soon as the application is actually started.
The graphical settings of the splash-screen are defined in the static.properties file in the \CustomizationTool\input\conf folder. In this file, you need to define the following elements for the splash screen image and background color:
splashscreenImage
splashscreenBackgroundColor
The splash screen image is centered, and not resized. The background color is applied to fill the screen.
