PostCSS Border 9-patch

PostCSS plugin to generate 9-patch like border styles.

Introduction

This plugin aims to bring a convenient conversion to border image styles for 9-patch effects. In Android we have a bunch of 9-patch toolsets; in iOS we have UIImage.resizableImageWithCapInsets. In CSS, 9-patch is achieved via appropriate combinations of border-width, border-image-source and border-image-slice rules.

Example

.bg {
    /* Input example */

    border-9-patch: url('bg.png') 110px 114px 52px 50px 50px 48px;
}

.foo {
    /* Output example */

    border-style: solid;
    border-color: transparent;
    border-image-source: url('bg.png');
    /* image dimension: 110px x 114px */
    border-width: 52px 50px 50px 48px;
    border-image-slice: 45.61% 45.45% 43.86% 43.64%;
}

Usage

postcss([ require('postcss-border-9-patch') ])

See PostCSS docs for examples for your environment.
