Small, black, but powerful!
Calimero is a high-performance Win32 (x86) console application designed to take full control of your Windows Desktop background (Windows 8 and up).

Features

  • Display Modes: Supports all native Windows modes (stretch, center, tile, fit, fill, span) plus custom implementations like cover, alternate, and upcoming gallery mode.
  • Multi-monitor Mastery: Native support for multi-monitor setups. Perfectly handles wide wallpapers, 4K assets, and complex spanning without blurriness.
  • Graphic Filters: Apply professional-grade filters via integrated libraries (paintLib, NexgenIPL, FreeImageRE, ImageMagick) or use custom built-in effects like GhostTrail, Echo, Pixelate, and more.
  • Smart Rescaling: Custom algorithms to resize images on-the-fly for the sharpest possible output.
  • Deep Customization: Print dynamic text over images, filter by size or wildcards, and sort by name, dimensions, etc.
  • Hypersonic Loading: Powered by the BerkeleyDB engine to manage thousands of files instantly. No more disk-thrashing or re-scanning directories every time you run it.
  • Seamless Navigation: Change wallpapers via a configurable timer or global hotkeys.
  • Cloud-Ready: Fetch images directly from the web using free services like Picsum.
  • Native & Lightweight: Zero bloated frameworks, zero SLOP. Just pure, “to-the-metal” Win32 C/C++. A small, black ugly console app, but deadly as a Ninja!
  • 100% Free: No telemetry, no hidden connections, no backdoors. Just code.
