+onloadCoords obj
+    A coordinates object with properties x1, y1, x2 & y2; for the coordinates of the select area to display onload
+
+The callback function
+
+The callback function is a function that allows you to capture the crop co-ordinates when the user finished a crop movement, it is passed two arguments:
+
+    * coords, obj, coordinates object with properties x1, y1, x2 & y2; for the coordinates of the select area.
+    * dimensions, obj, dimensions object with properities width & height; for the dimensions of the select area.
+
+An example function which outputs the crop values to form fields:
+Display code as plain text
+JavaScript:
+
+   1.
+      function onEndCrop( coords, dimensions ) {
+   2.
+          $( 'x1' ).value = coords.x1;

+Basic interface
+
+This basic example will attach the cropper UI to the test image and return crop results to the provided callback function.

+Select area ratio
+
+You can apply a ratio to the selection area, this example applies a 4:3 ratio to the select area.

+  17.

+
+With crop preview
+
+You can display a dynamically prouced preview of the resulting crop by using the ImgWithPreview subclass, a preview can only be displayed when we have a fixed size (set via minWidth & minHeight options). Note that the displayOnInit option is not required as this is the default behaviour when displaying a crop preview.

+Known Issues
+
+    * Safari animated gifs, only one of each will animate, this seems to be a known Safari issue.
+    * After drawing an area and then clicking to start a new drag in IE 5.5 the rendered height appears as the last height until the user drags, this appears to be the related to another IE error (which has been fixed) where IE does not always redraw the select area properly.
+    * Lack of CSS opacity support in Opera before version 9 mean we disable those style rules, if Opera 8 support is important you & you want the overlay to work then you can use the Opera rules in the CSS to apply a black PNG with 50% alpha transparency to replicate the effect.
+    * Styling & borders on image, any CSS styling applied directly to the image itself (floats, borders, padding, margin, etc.) will cause problems with the cropper. The use of a wrapper element to apply these styles to is recommended.
+    * overflow: auto or overflow: scroll on parent will cause cropper to burst out of parent in IE and Opera when applied (maybe Mac browsers too) I'm not sure why yet.
+
+If you use CakePHP you will notice that including this in your script will break the CSS layout. This is due to the CSS rule
+
+form div{
+vertical-align: text-top;
+margin-left: 1em;
+margin-bottom:2em;
+overflow: auto;
+}
+
+A simple workaround is to add another rule directly after this like so:
+
+form div.no_cake, form div.no_cake div {
+margin:0;
+overflow:hidden;
+}
+
+and then in your code surround the img tag with a div with the class name of no_cake.
+
+Cheers

+// Autocompleter.Base handles all the autocompletion functionality 
+// that's independent of the data source for autocompletion. This
+// includes drawing the autocompletion menu, observing keyboard
+// and mouse events, and similar.
+//
+// Specific autocompleters need to provide, at the very least, 
+// a getUpdatedChoices function that will be invoked every time
+// the text inside the monitored textbox changes. This method 
+// should get the text for which to provide autocompletion by
+// invoking this.getToken(), NOT by directly accessing
+// this.element.value. This is to allow incremental tokenized
+// autocompletion. Specific auto-completion logic (AJAX, etc)
+// belongs in getUpdatedChoices.
+//
+// Tokenized incremental autocompletion is enabled automatically
+// when an autocompleter is instantiated with the 'tokens' option
+// in the options parameter, e.g.:
+// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
+// will incrementally autocomplete with a comma as the token.
+// Additionally, ',' in the above example can be replaced with
+// a token array, e.g. { tokens: [',', '\n'] } which
+// enables autocompletion on multiple tokens. This is most 
+// useful when one of the tokens is \n (a newline), as it 
+// allows smart autocompletion after linebreaks.

+// The local array autocompleter. Used when you'd prefer to
+// inject an array of autocompletion options into the page, rather
+// than sending out Ajax queries, which can be quite slow sometimes.
+//
+// The constructor takes four parameters. The first two are, as usual,
+// the id of the monitored textbox, and id of the autocompletion menu.
+// The third is the array you want to autocomplete from, and the fourth
+// is the options block.
+//
+// Extra local autocompletion options:
+// - choices - How many autocompletion choices to offer
+//
+// - partialSearch - If false, the autocompleter will match entered
+//                    text only at the beginning of strings in the 
+//                    autocomplete array. Defaults to true, which will
+//                    match text at the beginning of any *word* in the
+//                    strings in the autocomplete array. If you want to
+//                    search anywhere in the string, additionally set
+//                    the option fullSearch to true (default: off).
+//
+// - fullSsearch - Search anywhere in autocomplete array strings.
+//
+// - partialChars - How many characters to enter before triggering
+//                   a partial match (unlike minChars, which defines
+//                   how many characters are required to do any match
+//                   at all). Defaults to 2.
+//
+// - ignoreCase - Whether to ignore case when autocompleting.
+//                 Defaults to true.
+//
+// It's possible to pass in a custom function as the 'selector' 
+// option, if you prefer to write your own autocompletion logic.
+// In that case, the other options above will not apply unless
+// you support them.
