Swayimg: image viewer for Sway/Wayland

Swayimg is a lightweight image viewer for Wayland display servers.

In a Sway compatible mode, the viewer creates an "overlay" above the currently active window, which gives the illusion that you are opening the image directly in a terminal window.

Supported image formats

• JPEG (via libjpeg);
• JPEG XL (via libjxl);
• PNG (via libpng);
• GIF (via giflib);
• SVG (via librsvg);
• WebP (via libwebp);
• HEIF/AVIF (via libheif);
• AV1F/AVIFS (via libavif);
• TIFF (via libtiff);
• EXR (via OpenEXR);
• BMP (built-in);
• PNM (built-in);
• TGA (built-in).

Usage

swayimg [OPTIONS]... [FILE]...

See man swayimg for details.

Examples:

• View multiple files:

  swayimg photo.jpg logo.png
  

• Start slideshow for all files (recursively) in the current directory in random order:

• View using pipes:

  wget -qO- https://www.kernel.org/theme/images/logos/tux.png | swayimg -
