Capture Control

Input Mode Selection (macOS only)

  • On macOS, barcodes and tickets can be captured by using a built-in camera or through a camera connected via USB.
    • The camera capture mode is activated by clicking the button with the "Camera" icon in the upper left corner of the main window.
    • When accessing the camera for the first time, a dialog window will appear prompting the user to grant permission for accessing the camera. The permission may be adjusted later in the macOS settings.
  • Alternatively, barcodes and tickets can be scanned directly from the screen.
    • The screen capture mode is activated using the button with the "Screen" icon in the upper left corner of the main window.
    • The app requires a special permission for capturing screen contents. As long as the permission is missing, no other applications are visible to the app (only the desktop background without any application windows).
    • The permission must be granted in the macOS settings. If necessary, the app will show an informative dialog with a button that leads to the corresponding page in the system preferences.

Camera Capture

  • Barcodes are captured on iOS/iPhoneOS using a built-in camera.
  • On macOS, a built-in camera can be used if available. Alternatively, an external USB camera that has been properly detected and activated by the operating system may be employed.
    • Scanning speed and recognition performance strongly depend on the capabilities of the camera being used.
    • Make sure that a camera with sufficiently high resolution is used and that there is good lighting without any reflections at the point of capture.
  • If multiple cameras are available, the device that should be used can be specified in the app's settings (see section "Camera Configuration").

Screen Capture (macOS only)

  • Screen Capture records the macOS user interface, following the movement of the cursor. The output of the captured image is displayed within the main window of the app.
  • As soon as the cursor comes to rest for a short moment, the underlying image area is scanned for barcodes.
  • As long as the option key on the keyboard is pressed and held down, capturing will be frozen at the current location.
    • In this manner, the cursor can be moved to the desired location on the screen first and then evaluation may be started by releasing the key.
    • Alternatively, if the feature for applying barcodes automatically is disabled (see section "Apply Barcodes"), the recognition can be frozen after targeting a barcode at the desired screen location in order to perform manual confirmation in the app's main window.
  • Several zoom levels can be chosen for more precise detection (see section "Screen Capture (Settings)"). The active image area is enlarged accordingly and may appear pixelated.
