利用gulp 插件gulp.spritesmith 完成小图合成精灵图，并自动输出样式文件
安装依赖
yarn add gulp yarn add gulp.spritesmith 本次依赖的版本是： "gulp": "^3.9.1" "gulp.spritesmith": "^6.5.1"
gulpfile.js的配置
const gulp = require("gulp")
// 本实例为完成精灵图的合并
const spritesmith = require("gulp.spritesmith")
gulp.task('sprite',function(){
gulp.src("images/*.png")
.pipe(spritesmith({
imgName:'images/sprite.png', //合并后大图的名称
cssName:'css/sprite.less',
padding:2,// 每个图片之间的间距，默认为0px
cssTemplate:(data)=>{
// data为对象，保存合成前小图和合成打大图的信息包括小图在大图之中的信息
let arr = [],
width = data.spritesheet.px.width,
height = data.spritesheet.px.height,
url = data.spritesheet.image
// console.log(data)
data.sprites.forEach(function(sprite) {
arr.push(
".icon-"+sprite.name+
"{"+
"background: url('"+url+"') "+
"no-repeat "+
sprite.px.offset_x+" "+sprite.px.offset_y+";"+
"background-size: "+ width+" "+height+";"+
"width: "+sprite.px.width+";"+
"height: "+sprite.px.height+";"+
"}\n"
)
})
// return "@fs:108rem;\n"+arr.join("")
return arr.join("")
}
}))
.pipe(gulp.dest("dest/"))
})
未合并前的效果
小图文件未合并前的效果如下(小图一共40张)
合并之后的效果：图片与less
