ImageConcat

ImageConcat development based on the GM, used to implement the PNG image concat, generation "Sprite Image", and export the JSON&CSS data.

合并多张png小图，并生成相应的CSS/JSON文件

Start

ImageConcat是基于gm开发，首先安装gm

npm install gm 

注意：gm需要安装ImageMagick或者GraphicMagick,详情请看gm

ImageConcat 安装

npm install imageConcat

运行：

var ic = require('imageConcat');
ic.init({
    source:'./dist/sprites/',
    imgDir:'dist/sprites/',
    dataType:'json,css', 
    dataDir:'dist/sprites/',
    direction:1,
    prefixer:['babyFade','bigEat'],
});

• source: 图片资源路径
• imgDir: 导出图片的路径
• dataType: 同时生成json、css，或只生成一个
• dataDir: 数据生成的地址
• direction: 排列方式 1 horizontial 0 vertical.
• prefixer: 根据前缀生成的多个sprite图片,如果不写将全部图片生成到一张图中
