Discontinued: I still like that app, but I gave up in the face of the dependency hell. Electron and React should not be used on base on a boiler plate template...

• shows pictures (jpg) in directories or playlists (txt, m3u)
• digital photo frame mode
  • selects randomly folders and shows a handful pictures (so not like the standard digital photo frame, who jumps immediatly to the next folder => minimizes headache caused by context jumping...)
  • filter directories by name snippets (white- and blacklists)
  • filter images by rating or tags (xmp; white- and blacklists)
  • favors images by rating
• integrated Exiftool
  • show image details (date, rating, camera + lens models, gps location)
  • open image location in browser (if any; predefined is openstreetmap)
• supports ICC color profiles
• fullscreen modus available
• transitions (at moment only crossfades)
• configuration via file (ini style) and some command line options
• runs on Linux and Windows
• screensaver mode: exits at the first mouse move or key press (see tools/screensaver.sh)
• able to block the system power saving for some time
• drag&drop images or directories (you can also drop several dirs at once => temporary playlist)

Download binaries from the release pages.

npm package manager is required.

$ git clone --depth=1 https://github.com/rosenloecher-it/roloviewer
# install prerequisites
$ npm install
# start development version
$ npm run dev
# start production version
$ npm start
# create linux binary
$ npm run package-linux
# create windows binary
$ npm run package-win

Most functionality is self explanatory - see menu or the hot key list (F1).

Some of the configuration has to be written into a file (e.g. filtering by tags and rating, blacklisting).

There are some commandline switches which overwrite the settings from config file.

Location:

• Linux: $HOME/.config/RoloViewer/roloviewer.ini
• Windows: %APPDATA%\RoloViewer\roloviewer.ini
