jQuery.colorMatrix.js

A jQuery plugin for applying SVG and CSS colormatrices to inline images.

Why?

You can easily apply crossbrowser color changes to images, as long as these changes are within the possibilities of CSS and SVG filters. By default, grayscale and inverted colors are supported*.

• Tested in Chrome, Firefox, Safari and IE8+
• Uses CSS filters if supported
• Extendable**

* Sepia tint is included, but doesn't work in IE version 9 and lower

** More options (for example: hue rotation) are possible. It's not currently integrated in the plugin, though.

Installation

Install with Bower

$ bower install jquery-colormatrix 

Or: include files

Include the plugin's JavaScript and CSS files. Have a look at the examples for further customization.

Plugin options

The plugin accepts a few parameters:

className

`string` - Name of the class that will be added to the image
_default: "grayscale"_

type

`string` - Type of the `` element
_default: "saturate"_

ids

`array` - Identifiers for both `` elements
_default: ["desaturate", "normal"]_

values

`array` - Colormatrix values for both `` elements
_default: [0, 1]_

Examples

Auto-trigger

Adding class="grayscale" to images will auto-trigger the plugin.

<img src="path/to/image.png" alt="My image" class="grayscale" />

Manual configuration

When applying the plugin through JavaScript, you have full control over the available options. You can invert colors by adding the following script to your site:

$(".invert").colorMatrix({     className:  "invert",     type:       "matrix",     ids:        ["invert", "normal"],     values:     ["-1 0 0 0 1 0 -1 0 0 1 0 0 -1 0 1 0 0 0 1 0",                  "1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0"] })

Note that, if the browser supports CSS filters, CSS rules will be applied to the image. If you want to use a custom colormatrix, you should define it in both JavaScript as well as CSS (or LESS)
