eth-blockies-wasm-js (develop preview)

• Note: The current version is a develop preview (pre-alpha) version, so functions and their signatures are not guaranteed to be fixed.
  If you use this version, use with caution!

  • Porting from the Rust library eth-blockies-rs...
  • Currently not optimized yet in its binary size & performance
    (seems to be much faster than the pure JS version when generating millions of blockies, though)

• Examples of the current version:

  import * as ethBlockies from 'eth-blockies';
    
  const size = 8; // between 5-16
  const seed = '0x63006c2d5428b6c7ab64b773980831f0a3edf77b'; // for Ethereum address seed, the seed string must be lowercase
  const outputPngDim = [32, 32];
  const outputAnsiDim = [8, 8];
  const rgbToGray = rgb => Math.round(rgb[0] * 0.299 + rgb[1] * 0.587 + rgb[2] * 0.114)
    
    
    
  // list all functions
  console.log('\n<<< function list >>>\n',
      Object.keys(ethBlockies.default).filter(el => !el.startsWith("__")),
      '\n');
    
    
    
  // base data
    
  const data = ethBlockies.data(size, seed);
  console.log('\n<data> (' + data.constructor.name + ')\n', data);
    
  const dataMapped = ethBlockies.dataMapped(size, seed, rgbToGray);
  console.log('\n<dataMapped> (' + dataMapped.constructor.name + ')\n', dataMapped);
    
  const indexedData = ethBlockies.indexedData(size, seed);
  console.log('\n<indexedData> (' + indexedData.constructor.name + ')\n', indexedData);
    
  const indexedDataMapped = ethBlockies.indexedDataMapped(size, seed, rgbToGray);
  console.log('\n<indexedDataMapped> (' + indexedDataMapped.constructor.name + ')\n', indexedDataMapped);
    
    
    
  // encoded data
  const ansiseqData = ethBlockies.ansiseqData(size, seed, outputAnsiDim, true); // true: is_utf8
  console.log('\n<ansiseqData> (' + ansiseqData.constructor.name + ')\n', ansiseqData);
    
  const pngData = ethBlockies.pngData(size, seed, outputPngDim);
  console.log('\n<pngData> (' + pngData.constructor.name + ')\n', pngData);
    
  const pngDataBase64 = ethBlockies.pngDataBase64(size, seed, outputPngDim, true); // true: prepend data_uri string
  console.log('\n<pngDataBase64> (' + pngDataBase64.constructor.name + ')\n', pngDataBase64);
    
  const compressedPngData = ethBlockies.compressedPngData(size, seed, outputPngDim);
  console.log('\n<compressedPngData> (' + compressedPngData.constructor.name + ')\n', compressedPngData);
    
  const compressedPngDataBase64 = ethBlockies.compressedPngDataBase64(size, seed, outputPngDim, true); // true: prepend data_uri string
  console.log('\n<compressedPngDataBase64> (' + compressedPngDataBase64.constructor.name + ')\n', compressedPngDataBase64);
