slide

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.

Tested versions:

• Raspberry Pi 3 running Raspbian Stretch.
• Raspberry Pi 3 running Raspbian Buster.

Screen background is filled with a scaled version of the image to prevent pure black background.

Usage

slide [-t rotation_seconds] [-o background_opacity(0..255)] [-b blur_radius] [-f fullscreen_flag(true/false)] -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
• fullscreen_flag: flag indicating whether to display fullscreen, default is true

Dependencies

• libexif
• qt5

sudo apt install libexif12 qt5-default

Build

dev libs needed to build slide on from source:

sudo apt install libexif-dev

mkdir -p make
cd make
qmake ../src/slide.pro
make
sudo make install
