This plug-in can easily convert any colored image into a B&W greyscale image. It uses the the HTML5 canvas tag and a fallback for the old browsers. There are three options to choose from – normal, hover effect inverted and ajax content.
You can easily implement it in your projects and achive classy look of your images.
Usage
1 Include the plug into the page:
<script src="js/jQuery.BlackAndWhite.js"></script>
2 Set the image wrappers using the css:
.bwWrapper {
position:relative;
display:block;
}
3 Initialize the plug in on window load (no $(document).ready()):
$(window).load(function(){
$('.bwWrapper').BlackAndWhite({
hoverEffect : true, // default true
// set the path to BnWWorker.js for a superfast implementation
webworkerPath : false,
// for the images with a fluid width and height
responsive:true,
// to invert the hover effect
invertHoverEffect: false,
speed: { //this property could also be just speed: value for both fadeIn and fadeOut
fadeIn: 200, // 200ms for fadeIn animations
fadeOut: 800 // 800ms for fadeOut animations
},
onImageReady:function(img) {
// this callback gets executed anytime an image is converted
}
});
});
