212 Chapter 13: Thumbnail Generation
13.5 Logging
Thumbnail Generator has its own log files (e.g. viz_thumbnailgenerator.log).
The logfiles are normally located in the program folder; however, you can also
place the log files in other directories using the -logpath <path> command line
parameter (added to your program shortcut’s target path). If you only want to
enable logging you can use the -dologging command line parameter.
