smallpic-2-css

Generate css from specify small pictures. This is not a sprite generator, we don't generate a sprite picture, but css with url as background-image instead.

smallpic-2-css is designed for legacy projects which you are planning to remove compass sprite usage with url-loader way proposed by webpack.

Let's say you already have a folder that contains lots of small pictures, and they were supposed to combined to sprite picture with css. Now, if you are going to do in webpack way, you don't need a sprite picture anymore, but css is still required. Try this library.

Installation

npm install smallpic-2-css --save

Usage

var gen = require('smallpic-2-css');

gen('root/logo/*.png', {
    out: cssPath,
    urlRoot: '../logo/',
    picSizeLimit: 10240, //picture will be ignored while generating css
    quite: true,    //warning will be ignored
    prefix: 'img-'  //prefix will be used in front of each generated class
}, function(err){
    if(err){
        //error occurred while generating css
    }
});

In above example, let's say we have following structure:

|root
|----logo/
|    |---es6.png
|    |---react-logo.png

The css will be generated to root/dist/generated.css, and content would be like this:

.img-es6{
    width: 406px;
    height: 140px;
    background-image: url(../logo/es6.png);
}
.img-react-logo{
    width: 391px;
    height: 377px;
    background-image: url(../logo/react-logo.png);
}
