Configuration Settings - nasa-jpl/LiveViewOpenCL GitHub Wiki

Overview

LiveView offers a configuration file which contains many useful preferences that change the application behavior. Although these settings can be changed from within the application, sometimes it is better or faster to modify parameters outside of the application. The LiveView configuration file, lvconfig.ini, is stored in a standard yet system-dependent location on the disk. Please see the list below for standard locations of the config file:

  • Linux: ~/.config/LiveView/lvconfig.ini or /etc/xdg/LiveView/lvconfig.ini
  • MacOS: ~/Library/Preferences/LiveView/lvconfig.ini

Contents of the LiveView Configuration file
