LightningView Image Viewer and Browser

A lightning-fast cross-platform image viewer written in Rust

This is a very slim image viewer that aims to replicate the most important functions found in commercial software like ACDSee.

Core Design goals

  • Lightweight
  • Cross Platform
  • Common image format support
  • RAW file support for popular cameras
  • Browsing through the current directory with arrow keys
  • Pan/Zoom with the mouse
  • Basic file operations such as deletion
  • Quick way to start the default image editor (planned)

Non-goals

  • Any form of image modification
  • File format conversion
  • Plugin system

Command Line Parameters

To start viewing images:

lightningview.exe <imagefile.ext>

To open an image in windowed mode instead of fullscreen:

lightningview.exe /windowed <imagefile.ext>

To register as default program for viewing images on older versions of Windows:

lightningview.exe /register

To remove this registration from your windows registry and settings:

lightningview.exe /unregister
