Since no event handlers have been attached it only performs
the cropping behavior.

<label>H <input type="text" size="4" id="h" name="h" /></label>
</div>
</form>
<p>
<b>An example with a basic event handler.</b> Here we've tied
several form values together with a simple event handler invocation.
The result is that the form values are updated in real-time as
the selection is changed using Jcrop's <em>onChange</em> handler.
</p>
<p>
That's how easily Jcrop can be integrated into a traditional web form!

<b>An example implementing a preview pane.</b> Obviously the most visual demo, the preview pane is accomplished entirely outside of Jcrop with a simple jQuery-flavored callback. This type of interface could be useful for creating a thumbnail or avatar. The onChange event handler is used to update the view in the preview pane.

<b>Experimental shader active.</b>
Jcrop now includes a shading mode that facilitates building
better transparent Jcrop instances. The experimental shader is less
robust than Jcrop's default shading method and should only be
used if you require this functionality.
</p>
<p>
<b>Animation/Transitions.</b>
Demonstration of animateTo API method and transitions for bgColor
and bgOpacity options. Color fading requires inclusion of John Resig's
jQuery <a href="http://plugins.jquery.com/project/color">Color
Animations</a> plugin. If it is not included, colors will not fade.
