MapToWordCloud

---

地图GeoJson多边形数据转相似形状词云图片

Turn GeoJson polygon data into wordcloud picture of similar shape.

1 安装 / Install

npm install maptowordcloud --save

2 使用 / Use

let geojson = geojson// 单个多边形的geojson数据
let wordcloudData = let wordcloudData = [
    ['la', 30],
    ['li', 28],
    ['lu', 26],
    ['le', 24],
    ['lo', 22],
    ['la', 20]
]
let opt = {
    list: wordcloudData,
    gridSize: 4,
    weightFactor: 1,
    fontFamily: 'serif',
    color: 'random-light',
    backgroundColor: 'rgba(0,0,0,0.0)',
    rotateRatio: 0.3,
    rotationSteps: 3,
    wait: 0
}
MapToWordCloud(geojson.features[0], opt, 10).then(src => {
    document.getElementById('wordcloud').src = src
})

3 目前待解决问题 / Current Issues

1. 最后生成的图片无法与原图形非常贴合 / Image generated does not match with polygon perfectly
2. 生成的图片大小不一，空白区域多 / Image generated have a lot of blank areas
3. 无法很好应对奇形怪状的多边形，因为用的wordcloud2.js的shape / Does not compatible well with polygons with weird shapes
