    What's it?

    lowpoly.js is a JS liberary which can style an image with Low Poly.

    Img

    Img

    Install

    npm install lowpoly
    

    Usage

    Note that lowpoly.js was written in ES6, it would work fine in the lastest version of morden browsers, or use it with Babel.

    import LowPoly from 'lowpoly'
    
    new LowPoly(src, config) .init() .then((data) => { ... })
    

    After the init() function, it will returns a promise, which includes a base64 source of the low-poly style image.

    Params

    | Param | Type | Description | | --- | --- | --- | | src | {String} | Address of an original image | | config | {Object} | The configuration object |

    The configuration object might take 6 properties:

    EDGE_DETECT_VALUE: Lower this to increase edge contrast sensitivity.

    POINT_RATE: Number of points distribution ratio of points (number) on the edge, detail, generated higher see console.

    POINT_MAX_NUM: Maximum points sampled. Higher = more detail.

    BLUR_SIZE: Smaller is more detailed.

    EDGE_SIZE: Larger is more detailed.

    PIXEL_LIMIT: Images may have this many pixels at most (width x height) or will be resampled. Have had no trouble setting this to ~10,000,000 or more.

    @vimutt 这不是 node 呀,就一个普通的 js 库,不过是用了 es6 的特性而已,用法很简单的,看文档就可以啦
