示例1: default
export default(seed: string) => {
// Init randomizer
const random = seedrandom(seed);
// 各チャンネルをランダムに決定
const r = Math.floor(random() * 255);
const g = Math.floor(random() * 255);
const b = Math.floor(random() * 255);
// 輝度(重み付き)
const luminance = Math.floor(
rWeight * r + gWeight * g + bWeight * b);
// 16進數に変換
const rHex1 = r.toString(16);
const gHex1 = g.toString(16);
const bHex1 = b.toString(16);
// 0埋め
const rHex2 = `0${rHex1}`.slice(-2);
const gHex2 = `0${gHex1}`.slice(-2);
const bHex2 = `0${bHex1}`.slice(-2);
// フォーマット
const background = `#${rHex2}${gHex2}${bHex2}`;
const foreground = luminance > 180 ? '#000' : '#fff';
return {
background,
foreground
};
};示例2: multinomialInternal
protected multinomialInternal(
probabilities: Array1D, numSamples: number, seed: number): Array1D {
