Sierra Lite Dither

Sierra Lite is the fastest variant of the Sierra family of dithering algorithms. Using only a single-row diffusion pattern, it provides quick processing while still producing quality results for real-time applications.

Effect ID: dither-sierra-lite

Example Configuration

sierra-lite.json
{
  "effectId": "dither-sierra-lite",
  "dither": {
    "pattern": "sierraLite",
    "pixelation": 4,
    "paletteId": "monochrome",
    "colors": ["#000000", "#ffffff"],
    "brightness": 1,
    "contrast": 1,
    "threshold": 0.5
  }
}

Error Diffusion Matrix

Sierra Lite uses an extremely compact matrix:

  *   2      (row 0: current row)
  1   1      (row 1: next row)

  Divisor: 4

Characteristics

  • Fastest Sierra - Minimal calculations per pixel
  • Real-time friendly - Excellent for video and animation
  • Compact spread - Error stays localized
  • Sharp texture - More visible grain than larger matrices

Sierra Family Comparison

  • Sierra (full) - 3 rows, smoothest, slowest
  • Two-Row Sierra - 2 rows, balanced
  • Sierra Lite - 1+ row, fastest, most texture

Tips

  • Ideal for real-time video effects where speed matters
  • Works well with high-contrast images
  • Use when you want visible dither texture
  • Combine with scanlines for retro gaming aesthetic
