Simple, lightweight slideshow selecting random images from specified directory. This slideshow is designed to compile and run also on a Raspberry Pi, for example to turn it into a digital picture frame.
- Raspberry Pi 3 running Raspbian Stretch.
Screen background is filled with a scaled version of the image to prevent pure black background.
slide [-t rotation_seconds] [-o background_opacity(0..255)] [-b blur_radius] -p image_folder
image_folder: where to search for images (.jpg files), currently non-recursively
rotation_seconds(default=30): time until next random image is chosen from the given folder
background_opacity(default=150): opacity of the background filling image between 0 (black background) and 255
blur_radius(default=20): blur radius of the background filling image
