Description

Hi HN!I'd like to share my app for viewing images the way I find comfortable on a desktop computer. No window frame, no menus, no toolbars, just the image itself in transparent fullscreen overlay; pan (move around) with mouse with left button pressed (or keyboard arrows), zoom into point under cursor with scroll (or into point at center of display with keyboard +=/-/0), close with left click anywhere (or keyboard Enter, allowing "instant toggle" between file manager and image view). Written in C and Rust with SDL3 and image-rs.Source and builds for Linux (Ubuntu 25.10, Nix expr) and Windows: https://github.com/shatsky/lightning-image-viewerMicrosoft store (with screenshot): https://apps.microsoft.com/detail/9np4j8k90smkWeb demo: https://shatsky.github.io/lightning-image-viewer/Dev notes: https://shatsky.github.io/notes/2025-03-07_sdl3-image-viewer...

Could you build this?

Yes It is a lightweight desktop image viewing utility with pan/zoom controls and transparent fullscreen overlay, easily implemented using frameworks like Tauri, Electron, or native Rust/C++ bindings with AI assistance.
