About

Dither Pro 2.0 is a standalone Windows application designed to bring advanced image dithering algorithms to a modern, accessible desktop interface. Unlike web-based or cloud-dependent tools, Dither Pro runs entirely on your local machine, ensuring maximum performance and complete privacy for your files.

Whether you are looking to emulate 1-bit Macintosh graphics, prepare images for E-Ink displays, or create retro "pixel art" aesthetics, Dither Pro provides the granular control needed for professional results without requiring an internet connection.

Key Features

Advanced Dithering Engines

Access a library of industry-standard error diffusion and ordered dithering algorithms:

• Error Diffusion: Floyd-Steinberg, Atkinson, Jarvis-Judice-Ninke, Stucki, Burkes, Sierra (Lite, 2-Row, 3-Row).
• Ordered patterns: Bayer matrices (2x2, 4x4, 8x8) and Cluster Dot halftones.
• Serpentine Scanning: Reduce linear artifacts by processing pixels in alternating directions.

Color Science

• Custom Palettes: Built-in presets for Gameboy, CGA, Neon, Vaporwave, and Monochrome.
• Dynamic Quantization: Generate optimized palettes from your source image using Median Cut or Popularity algorithms.
• Perceptual Matching: Toggle between Euclidean distance and "Redmean" color metrics for human-eye accuracy.

Professional Workflow

• Non-Destructive Editing: Full Undo/Redo history stack.
• Live Split-View: Compare your original image and the dithered output side-by-side in real-time.
• Image Enhancement: Built-in pre-processing for brightness, contrast, saturation, blur, and sharpening.
• Pixel Scaling: Downsample images (1x to 8x) for authentic retro resolution emulation.

Performance

• Local Processing: No API calls. No uploads. 100% Offline.
• Native Architecture: Optimized for Windows to handle heavy computation and high-resolution images with zero latency.
