fis-spriter-csssprites
Advanced tools
基于FIS的csssprites,对css文件以文件为级别进行csssprites处理。支持repeat-x
, repeat-y
, background-position
###安装
$ npm install -g fis-spriter-csssprites
####环境要求 0. 依赖native插件,node-images 环境需要符合个插件的要求。(OS X、Windows、Linux x86 提供了二进制包) 0. 只能在FIS中使用
###配置
fis.config.merge({
namespace: 'demo',
modules: {
spriter: 'csssprites'
},
roadmap: {
path: {
reg: /\static\/.*\.css$/i
//配置useSprite表示reg匹配到的css需要进行图片合并
useSprite: true
}
}
pack: {
//对合并的aio.css进行处理
'aio.css': [
'**.css'
]
},
settings: {
spriter: {
csssprites: {
//图之间的边距
margin: 10,
//使用矩阵排列方式,默认为线性`linear`
layout: 'matrix'
}
}
}
});
###使用
调用执行spriter,需要fis release
时加-p
参数: fis release -p
,具体请参照文档
在书写css时标注background-image
的图片是否进行合并,标注说明;
通过图片添加query识别图片是否需要做图片合并,具体
query | 说明 |
---|---|
?__sprite | 标识图片要做合并 |
支持图片的background-position:有的情况下引用的图片已经是合并了几个小图的图片,通过background-position
来显示每个小图,这种情况也是支持的。
支持以下几种background-position
,有的同学不知道background-position
是如何工作的,请参见MDN
支持写法 | 示例 | 使用场景 |
---|---|---|
background-position: \d+px \d+px; | background-position: -9px -1px; | 需要合并的图是一个合并了很多小图的图片 |
background-position: left \d+px; | background-position: left -11px; | 需要合并的图片向左浮动 |
background-position: right \d+px; | background-position: right -1px; | 需要合并的图片向右浮动 |
background-position: left top; | background-position: left top; | 需要合并的图片向左浮动 |
background-position: right top; | background-position: right top; | 需要合并的图片向右浮动 |
###示例
源代码: aio.css
.header, .footer {
background: url(/img/1px_bg.png?__sprite) repeat-x;
height: 150px;
width: 960px;
}
.nav {
min-height: 400px;
width: 100px;
background: url(/img/nav_bg.png?__sprite) repeat-y;
}
.icon_add {
width: 25px;
height: 25px;
background: url(/img/icon/add.jpg?__sprite) no-repeat;
}
.icon_mul {
width: 25px;
height: 25px;
background: url(/img/icon/mul.jpg?__sprite) no-repeat;
}
产出结果:
.header, .footer {
height: 150px;
width: 960px;
background-repeat: repeat-x
}
.nav {
min-height: 400px;
width: 100px;
background-repeat: repeat-y
}
.icon_add {
width: 25px;
height: 25px;
background-repeat: no-repeat
}
.icon_mul {
width: 25px;
height: 25px;
background-repeat: no-repeat
}
.header, .footer {
background-position: 0px 0px;
}
.nav {
background-position: 0px 0px;
}
.icon_add {
background-position: 0px 0px;
}
.icon_mul {
background-position: 0px -25px;
}
.header, .footer {
background-image: url('aio_x.png');
}
.nav {
background-image: url('aio_y.png');
}
.icon_add, .icon_mul {
background-image: url('aio_z.png');
}
如上,1px_bg.png
会合并到aio_x.png
(aio.css对应图片), nav_bg.png
合并到aio_y.png
, add.jpg
和mul.jpg
被合并到aio_z.png
。
