Usage: amiga-convert

Options:
--colors Number of colors in palette (2-4096, default: 32)

--quant Color quantization algorithm (default: rgbquant)
- rgbquant: Spatial color quantization (fast, best all-round)
- wuquant: Xiaolin Wu's algorithm (very fast, good quality)
- neuquant: Neural network (slow, poor for small palettes)
- median-cut: Classic median cut (fast, decent quality)

--dither Dithering algorithm (default: floyd-steinberg)
- none: No dithering, nearest color
- floyd-steinberg: Error diffusion (best for photos)
- atkinson: Error diffusion with lighter touch
- ordered: Bayer matrix dithering (retro look)

--dither-amount Dithering strength (0.0-1.0+, default: 1.0)
Lower values = less dithering, higher = more

--bayer-size Bayer matrix size for ordered dithering (2, 4, or 8)
Default: 8
