<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.
