CVI
curl.js 1.4 allows you to add an page curl effect (inc. backside mask) to images on your webpages. It uses unobtrusive javascript to keep your code clean.

It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, Safari and IE6+. On older browsers, it'll degrade and your visitors won't notice a thing.

Demonstration

Shows some of the things curl.js does.

First Image with class = "curl invert", others with class = "curl isizeN" (different sizes)...

If you want flexibility, use "cvi_curl_lib.js" instead of "curl.js". You can make your curls respond to user actions (e.g. changing the curl size when the image is hovered over).

Setting Up

Download curl.js and include it into your webpage.

<script type="text/javascript" src="curl.js"></script>

Using It

To get the page curl effect just add a class="curl" to the image (minimum dimension: 64x64).

Classes

Scripting lib

If you want flexibility, use "cvi_curl_lib.js" instead of "curl.js". You can make your curls respond to user actions (e.g. changing the curl size when the image is hovered over).

Set defaults using Javascript
cvi_curl.defaultSize = 33; //INT 0-100 (% curling)
cvi_curl.defaultShadow = 66; //INT 0-100 (% opacity)
cvi_curl.defaultColor = 0; //STR '#000000'-'#ffffff' or 0
cvi_curl.defaultInvert = false; //BOOLEAN
If cvi_filter_lib.js is loaded also...
cvi_curl.defaultFilter = null; //OBJ [{f='grayscale'},{f='emboss', s:1}...]

Add images using Javascript
cvi_curl.add(image, options);
image should be an image element: document.getElementById("myimg")
options can contain one or more values: {size: value, shadow: value, color: value, invert: value, filter: value}
Examples:
cvi_curl.add(document.getElementById("myimg"), { shadow: 75, size: 50 });
<img onLoad="cvi_curl.add(this, { shadow: 75, size: 50 });" ...>

Modify images using Javascript
cvi_curl.modify(image, options);
If the image has already an effect but a option value has changed, the effect will be changed accordingly.
Example:
cvi_curl.modify(document.getElementById("myimg"), { size: 100 });

Remove effect from an image using Javascript
cvi_curl.remove(image);

Support libs

If you are using the more flexible "cvi_curl_lib.js" instead of "curl.js", you'll get access to additional features by the following support libraries (part of distribution):

Why use Javascript Image Curl?

In older browsers, the script degrades and your visitors won't notice a thing.
