✨ glslideshow — the manual, but make it fashion 💅

okay bestie, welcome to glslideshow, a page from the XScreenSaver manual, and honestly? it's giving art gallery. it's giving screensaver that understood the assignment. let's go 🎀

🌸 NAME 🌸

glslideshow — a slideshow of images using smooth zooming and fades ✨

🦋 SYNOPSIS 🦋

[--root] [--window-id number] [--duration seconds] [--transition
seconds] [--pan seconds] [--fade seconds] [--letterbox | --clip] [--zoom
percent] [--titles] [--delay usecs] [--fps] [--verbose] [--debug]
[--wireframe]

💖 DESCRIPTION 💖

So what it does is: it displays a slideshow of images, and it does it with panning, zooming and crossfading effects. yes. it's a whole vibe. main character energy for your desktop, fr fr. 🌈

Now, about where the pictures come from — and this is the part ppl always ask about: to specify the directory that images are loaded from, you run xscreensaver-settings(1) and click on the "Advanced" tab. that's it. that's the whole trick. iykyk 🫶

✨ OPTIONS ✨

  • --visual visual — pick which visual to use. legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. so like, name it or number it, your call 💅
  • --window — draw on a newly-created window. this is the default, bestie.
  • --root — draw on the root window.
  • --window-id number — draw on the specified window. you give it a number, it draws there. obsessed.
  • --duration seconds — how long each image chills on screen before a new one gets loaded. Default 30 seconds. a whole half a minute of a moment. iconic.
  • --transition seconds — when a new image is loaded, it transitions onto the screen by sliding in from the edges, spinning or flipping. this is how long that transition takes. set it to 0 to disable the transition effects. Default 3 seconds. the drama of the entrance? unmatched 🎬
  • --pan seconds — once an image has been loaded, it gets panned, zoomed and cross-faded against itself. this is how fast those pans are. set this to 0 to disable the panning-and-crossfading effect. Default 6 seconds.
  • --fade seconds — when zooming and cross-fading, this is how long the "fade" portion takes. 🚨 this value must be less than the pan option (it is inclusive). set this to 0 to disable the panning-and-crossfading effect. Default 2 seconds. respect the math, babes.
  • --letterbox — whether to fit the image on the screen (adding horizontal or vertical black bars) or to fill the screen (cropping the image). this is the default.
  • --clip — the opposite of --letterbox. that's the entire description. periodt.
  • --zoom number — zoom in on the image a little bit. this applies both to "transitions" and to "panning-and-crossfading". Default: 75, meaning that 75% or more of each image will always be visible. if you always want to see 100% of every image, then use "letterbox" and set "zoom" to 100%. 🙈
  • --titles — whether to show the file name of the current image in the upper left corner. yes, like a lil museum plaque 🎀
  • --delay number — per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
  • --fps — display the current frame rate, CPU load, and polygon count. nerd stats, we love her 🔥
  • --verbose — prints debugging info to stderr.
  • --debug — draw some diagnostic rectangles.
  • --wireframe — another debug mode.

🌈 ENVIRONMENT 🌈

  • DISPLAY — to get the default host and display number.
  • XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
  • XSCREENSAVER_WINDOW — the window ID to use with --root.
