# DigiKam Screensaver
[](https://github.com/bohdanbobrowski/digikam_screensaver/graphs/commit-activity) [](https://lbesson.mit-license.org/)   
Windows screensaver, from pictures loaded out from DigiKam database in Python.
As for now - this is just for Windows.
## Instructions
## Features
- Takes random photos from digikam4.db SQLite database (`*.jpg`, `*.gif` and `*.png`) with a minimum rating according settings (by default it's one star).
- Some configuration is needed.
- Database is opened in read-only mode!
- Pressing `` will (obviously) turn off screen saver, but I've added a function that will open current picture in associated app.
- Pressing `` will open project Github page.
## Known issues
- screensaver work just **for one monitor**
- **preview does not work**: _none of python screensaver examples has this feature_, and to make it working I need to
display screensaver in given window handler number (Windows passes it via cmdline, I'm parsing that but Tkinter AFAIK
can't display or create window inside other window): see how it's done
[here, in C](https://github.com/henrypp/matrix/blob/master/src/main.c).
- because of these two problems above, I'm considering change Tkinter to other library
([Arcade](https://api.arcade.academy/en/latest/index.html)? [Pygame](https://www.pygame.org/news)?) and keep Tkinter
just for configuration window
- the choice of Python for this kind of program (it's more for a demonstration - hold my beer, I'll show you something
cool) is not very optimal, mainly because of the size and the way the binary generated by PyInstaller works,
it's also like a **red rag to a bull for antiviruses**... but anyone who knows anything about PyInstaller will understand
## Dev environment
This will work on Windows cmd:
git clone [email protected]:bohdanbobrowski/digikam_screensaver.git
cd digikam_screensaver
python -m venv venv
venv\Scripts\activate
pip install -e '.[dev]'
Run configuration windows first:
python digikam_screensaver/screen_saver.py /c
It should look like this:
Then, to test how does it work just type:
python digikam_screensaver/screen_saver.py /s
Preview mode can be reached by typing:
python digikam_screensaver/screen_saver.py /c
### Building own *.scr
If all required stuff is installed in system, this command should make the job:
python digikam_digikam_screensaver_build.py
You'll find exe in `.\dist` folder - just rename it to scr and install.
