About:
Scale2x is a real-time graphics effect that produces a larger version of an input image without introducing blurring. It achieves this by intelligently interpolating pixels to create a sharp, scaled-up output that preserves the original's detail and clarity. This effect is particularly effective for pixel art and retro gaming graphics, providing a clean and crisp visual enhancement.
Key Features:
  • Real-time image scaling
  • Preserves pixel art sharpness
  • No blurring artifacts
  • Lightweight and fast
Use Cases:
  • Enhancing retro game graphics for modern displays
  • Pixel art upscaling in real-time applications
  • Improving visual quality of emulators
Alternatives:
  • xBRZ – xBRZ is another high-quality scaling algorithm, often considered more advanced but potentially more computationally intensive than Scale2x.
  • Nearest Neighbor – The simplest scaling method, which enlarges pixels without interpolation, resulting in a blocky but fast output.
