Featherweight Local Wallpaper

0-overhead background wallpaper plugin => Obsidian. Supports drag & drop to set local images without a local web-server (+ file-nav wallpaper). Rendered directly via GPU-accelerated CSS variables.

Features

• Local & Remote Support: Use local images on your system. (e.g., ~/Downloads/wallpaper.png) or external web URLs (https://...).

• Zero-Overhead Architecture: Uses native Obsidian resource paths and pure CSS custom properties (var(--...)). Rendering, scaling, and opacity are offloaded directly to Chromium's GPU compositor.

• Visual Fine-Tuning:

  • Adjustable opacity ($0\text{–}100%$)
  • Native Gaussian blur slider ($0\text{–}40\text{ px}$)
  • Translucent contrast overlay for text legibility
  • Darkness overlay slider for high-brightness images
  • (etc. Maybe add text-colour later)

Personal Note

3yrs ago, this was my first "real" programming project. I called it "Hoshikawa Version 1" or something like that. Anyway, I never put it onto obsidian community plugins because I was frustrated that I couldn't get local images to work and because I wanted way more customization like a colour picker (struggling to make a colour picker is what drew me further into programming). . . And all the important parts were 100% vibe coded or stolen.

I greatly regret that I didn't just go a little harder and published it as is but oh well? I got my friends to use it anyway.
