    Background Blur Plugin

    Background Blur plugin is a cross browser jQuery plugin for blurring images.

    See http://msurguy.github.io/background-blur/ for documentation and demos

    Installation and Usage

    Install the plugin with Bower:

    bower install background-blur

    Or with NPM:

    npm install background-blur

    Or manually:

    <script src="jquery.min.js"></script>
    <script src="background-blur.min.js"></script>

    Create a container which will contain the blurred image:

    <div id='some-element'></div>

    Then create a blurred image in that container:

    $('#some-element').backgroundBlur({
        imageURL : 'http://URL-of-the-image',
        blurAmount : 50,
        imageClass : 'bg-blur'
    });

    OR Create a blurred image and fade it in:

    $('#some-element').backgroundBlur({
        imageURL : 'http://URL-of-the-image',
        blurAmount : 50,
        imageClass : 'bg-blur'
        duration: 1000, // If the image needs to be faded in, how long that should take
        endOpacity : 1 // Specify the final opacity that the image will have
    });

    OR Create a blurred image, fade it in and switch to another image:

    // Initialize the blur
    $('#some-element').backgroundBlur({
        imageURL : 'http://URL-of-the-image',
        blurAmount : 50,
        imageClass : 'bg-blur'
        duration: 1000, // If the image needs to be faded in, how long that should take
        endOpacity : 1 // Specify the final opacity that the image will have
    });
     
    //Switch the image
    $('#some-element').backgroundBlur('http://URL-of-another-image');

    Browser Support:

    • Chrome
    • Firefox
    • Safari and Safari Mobile (iOS)
    • IE6, IE7, IE8 - blur is supported without animation (need to omit "duration" property in those browsers to make this plugin work, the problem will get fixed when Velocity.js issue gets fixed)
    • IE9, IE10, IE11
    • Android browsers

    Possibly, more. Please let me know if some browser doesn't work

    Under the hood:

    This plugin utilizes SVG filter to blur the image if SVG is supported by the browser (all except IE), otherwise the plugin creates an IMG tag and applies a special IE-only filter in CSS

    Q: Why not simply use CSS 3 blur filter? A: The browser support for SVG blur filter is much wider when it comes to older browsers.

    Velocity.js support:

    If you are using Velocity.js animation library, the plugin will automatically detect its presence and make fade in/fade out animations more performant, especially on mobile. If Velocity is not present on the page, jQuery's "animate" is used instead.

    Where is this used?
