clip-path-polygon Build Status

This is a jQuery plugin that makes using clip-path property easy on whatever tag under different browsers.

Tested on latest Chrome, Safari, Firefox and Opera.

It should work on Chrome ≥31, Firefox ≥31, Safari ≥7 and Opera ≥30.

What it does?

Let's say that you want to achieve something like this:

Take a look at the example html file!

So you need to have a rectangle (e.g. 300x200) and you have to crop this image with such coordinates: (0; 0), (145; 0), (150; 20), (155; 0), (300; 0), (300; 200), (0; 200), (0; 0)

Absolute values

In Webkit all you have to do is to write a css style: -webkit-clip-path: polygon(0 0, 145px 0, 150px 20px, 155px 0, 300px 0, 300px 200px, 0 200px, 0 0)

In Firefox and in W3C standard what you should do is: clip-path: url(#my-definition) and somewhere in the file:

<svg>
    <defs>
        <clippath id="my-definition">
            <polygon points="0 0, 145 0, 150 20, 155 0, 300 0, 300 200, 0 200, 0 0"></polygon>
        </clippath>
    </defs>
</svg>

Relative values

If your design is resposive, you might want to use relative unit - percents. Then, the expected values would be:

  • Webkit: polygon(0 0, 49% 0, 50% 10%, 51% 0, 100% 0, 100% 100%, 0 100%, 0 0)
  • Firefox: <polygon points="0 0, 0.49 0, 0.5 0.1, 0.51 0, 1 0, 1 1, 0 1, 0 0"></polygon>

clip-path-polygon does this job for you!

Installation

Npm

Install with https://npmjs.org or add it to your package.json:

$ npm install clip-path-polygon

Then require it:

require('clip-path-polygon');

and use:

$myElement.clipPath();

Bower

$ bower install clip-path-polygon --save

and then add bower_components/clip-path-polygon/build/clip-path-polygon.min.js to your scripts.

<script src="bower_components/clip-path-polygon/build/clip-path-polygon.min.js"></script>

I'm assuming here that your bower installation folder is called bower_components.

Browser

Download clip-path-polygon.min.js (minified) or clip-path-polygon.js (dev) and add it to you HTML file:

<script src="clip-path-polygon.min.js"></script>

Compilation

If you want to compile the whole package with unit tests, run: npm install and then grunt (compilation) or grunt test (tests).

I use mocha, sinonjs and expect.js for testing.

Changelog

Changlelog is available here: CHANGELOG.md

API

Definition: clipPath(points [, options])

You can call it on a jQuery element:

$('#my-element').clipPath(points);

where points is an array of two-elements arrays: [[x0, y0], [x1, y1], [x2, y2]...] crops the element to this area defined by these points.

There are some options that you can use:

Option Default Description
isPercentage *false* specifies whether you want to use absolute numbers (pixels) or relative unit (percents)
isForWebkit *true* specifies if `-webkit-clip-path` property should be added to element
isForSvg *true* specifies if `-clip-path` property and `` element should be added
svgDefId *clipPathPolygonGenId* specifies *id* of SVG clippath definition

Examples

Basic

<html>
  <head>
    <script src="jquery.min.js"></script> 
    <script src="clip-path-polygon.min.js"></script> 
    <script>
      $(function() {
        var points = [[0, 0], [145, 0], [150, 20], [155, 0], [300, 0], [300, 200], [0, 200], [0, 0]];
        $('#test').clipPath(points);
      });
    </script> 
  </head>
  <body>
    <div style="width: 300px; height: 200px">
      <div id="test" style="width: 100%; height: 100%; background-color: green"></div>
    </div>
  </body>
</html>

which gives you such an html code (remember that svg element has to have http://www.w3.org/2000/svg namespace!):

<div style="width: 300px; height: 200px">
  <div id="test" style="width: 100%; height: 100%; background-color: green;
    -webkit-clip-path: polygon(0 0, 145px 0, 150px 20px, 155px 0, 300px 0, 300px 200px, 0 200px, 0 0);
    clip-path: url(#clipPathPolygonGenId)"></div>
</div>
 
<svg>
  <defs>
    <clippath id="clipPathPolygonGenId">
      <polygon points="0 0, 145 0, 150 20, 155 0, 300 0, 300 200, 0 200, 0 0"></polygon>
    </clippath>
  </defs>
</svg>

Relative values

To use relative values, you have to pass isPercentage option. You might want to name the SVG clippath definition differently too:

<html>
  <head>
    <script src="jquery.min.js"></script> 
    <script src="clip-path-polygon.min.js"></script> 
    <script>
      $(function() {
        var points = [[0, 0], [49, 0], [50, 10], [51, 0], [100, 0], [100, 100], [0, 100], [0, 0]];
        $('#test').clipPath(points, {
          isPercentage: true,
          svgDefId: 'mySvg'
        });
      });
    </script> 
  </head>
  <body>
    <div style="width: 300px; height: 200px">
      <div id="test" style="width: 100%; height: 100%; background-color: green"></div>
    </div>
  </body>
</html>

which gives you such an html code (remember that svg element has to have http://www.w3.org/2000/svg namespace!):

<div style="width: 300px; height: 200px">
  <div id="test" style="width: 100%; height: 100%; background-color: green;
    -webkit-clip-path: polygon(0 0, 49% 0, 50% 10%, 51% 0, 100% 0, 100% 100%, 0 100%, 0 0);
    clip-path: url(#mySvg)"></div>
</div>
 
<svg>
  <defs>
    <clippath id="mySvg">
      <polygon points="0 0, 0.49 0, 0.5 0.1, 51% 0, 1 0, 1 1, 0 1, 0 0"></polygon>
    </clippath>
  </defs>
</svg>
