Example

import { randpix, RandpixColorScheme, Symmetry } from 'randpix'

const generate = randpix({
  colorScheme: RandpixColorScheme.DARKULA, // Color theme (default: NEUTRAL)
  size: 8, // Art size. Recommended 7 or 8 (odd/even symmetry) (default: 8)
  scale: 32, // Pixel scale (default: 1)
  symmetry: Symmetry.VERTICAL, // Symmetry (default: VERTICAL)
  color: [255, 100, 50], // [R, G, B] like color for solid art (default: undefined),
  seed: 'Some string', // Seed (default: undefined)
  colorBias: 15, // Slightly changes the color hue, which adds more color to the image (default: undefined)
  grayscaleBias: false // Change only the brightness of the color instead of the hue (default: undefined)
})

const art = generate() // Generating the pixel art

const pngBuffer = art.toBuffer('image/png')
const dataURL = art.toDataURL()

Custom color scheme

const customColorScheme = [
  // [R, G, B, C], C is the frequency of this color appearing in the pixel art
  [151, 219, 174, 1],
  [195, 229, 174, 0.5],
  [241, 225, 166, 0.5],
  [244, 187, 187, 0.2],
]
