Jcrop - Hello World
This example demonstrates the default behavior of Jcrop.
Since no event handlers have been attached it only performs
the cropping behavior.

Jcrop - Event Handlers
An example with a basic event handler. 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 onChange handler.
That's how easily Jcrop can be integrated into a traditional web form!

Jcrop - Aspect ratio w/ preview pane
| | |
An example implementing a preview pane. 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.
