+Options
+
+ratioDim obj
+    The pixel dimensions to apply as a restrictive ratio, with properties x & y.
+minWidth int
+    The minimum width for the select area in pixels.
+minHeight int
+    The mimimum height for the select area in pixels.
+maxWidth int
+    The maximum width for the select areas in pixels (if both minWidth & maxWidth set to same the width of the cropper will be fixed)
+maxHeight int
+    The maximum height for the select areas in pixels (if both minHeight & maxHeight set to same the height of the cropper will be fixed)
+displayOnInit int
+    Whether to display the select area on initialisation, only used when providing minimum width & height or ratio.
+onEndCrop func
+    The callback function to provide the crop details to on end of a crop.
+captureKeys boolean
+    Whether to capture the keys for moving the select area, as these can cause some problems at the moment.
+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;
+   3.
+          $( 'y1' ).value = coords.y1;
+   4.
+          $( 'x2' ).value = coords.x2;
+   5.
+          $( 'y2' ).value = coords.y2;
+   6.
+          $( 'width' ).value = dimensions.width;
+   7.
+          $( 'height' ).value = dimensions.height;
+   8.
+      }
+
+Basic interface
+
+This basic example will attach the cropper UI to the test image and return crop results to the provided callback function.
+Display code as plain text
+HTML:
+
+   1.
+      <img src="test.jpg" alt="Test image" id="testImage" width="500" height="333" />
+   2.
+       
+   3.
+          <script type="text/javascript" language="javascript">
+   4.
+          Event.observe( window, 'load', function() {
+   5.
+              new Cropper.Img(
+   6.
+                  'testImage',
+   7.
+                  { onEndCrop: onEndCrop }
+   8.
+              );
+   9.
+          } );
+  10.
+      </script>
+
+Minimum dimensions
+
+You can apply minimum dimensions to a single axis or both, this example applies minimum dimensions to both axis.
+Display code as plain text
+HTML:
+
+   1.
+      <img src="test.jpg" alt="Test image" id="testImage" width="500" height="333" />
+   2.
+       
+   3.
+      <script type="text/javascript" language="javascript">
+   4.
+          Event.observe( window, 'load', function() {
+   5.
+              new Cropper.Img(
+   6.
+                  'testImage',
+   7.
+                  {
+   8.
+                      minWidth: 220,
+   9.
+                      minHeight: 120,
+  10.
+                      onEndCrop: onEndCrop
+  11.
+                  }
+  12.
+              );
+  13.
+          } );
+  14.
+      </script>
+
+Select area ratio
+
+You can apply a ratio to the selection area, this example applies a 4:3 ratio to the select area.
+Display code as plain text
+HTML:
+
+   1.
+      <img src="test.jpg" alt="Test image" id="testImage" width="500" height="333" />
+   2.
+       
+   3.
+      <script type="text/javascript" language="javascript">
+   4.
+          Event.observe( window, 'load', function() {
+   5.
+              new Cropper.Img(
+   6.
+                  'testImage',
+   7.
+                  {
+   8.
+                      ratioDim: {
+   9.
+                          x: 220,
+  10.
+                          y: 165
+  11.
+                      },
+  12.
+                      displayOnInit: true,
+  13.
+                      onEndCrop: onEndCrop
+  14.
+                  }
+  15.
+              );
+  16.
+          } );
+  17.
+      </script>
+
+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

+ * Image Cropper (v. 1.2.0 - 2006-10-30 )

+ * Copyright (c) 2006 David Spurr (http://www.defusion.org.uk/)

+ * 

+ * The image cropper provides a way to draw a crop area on an image and capture

+ * the coordinates of the drawn crop area.

+ * 

+ * Features include:

+ * 		- Based on Prototype and Scriptaculous

+ * 		- Image editing package styling, the crop area functions and looks 

+ * 		  like those found in popular image editing software

+ * 		- Dynamic inclusion of required styles

+ * 		- Drag to draw areas

+ * 		- Shift drag to draw/resize areas as squares

+ * 		- Selection area can be moved 

+ * 		- Seleciton area can be resized using resize handles

+ * 		- Allows dimension ratio limited crop areas

+ * 		- Allows minimum dimension crop areas

+ * 		- Allows maximum dimesion crop areas

+ * 		- If both min & max dimension options set to the same value for a single axis,then the cropper will not 

+ * 		  display the resize handles as appropriate (when min & max dimensions are passed for both axes this

+ * 		  results in a 'fixed size' crop area)

+ * 		- Allows dynamic preview of resultant crop ( if minimum width & height are provided ), this is

+ * 		  implemented as a subclass so can be excluded when not required

+ * 		- Movement of selection area by arrow keys ( shift + arrow key will move selection area by

+ * 		  10 pixels )

+ *		- All operations stay within bounds of image

+ * 		- All functionality & display compatible with most popular browsers supported by Prototype:

+ * 			PC:	IE 7, 6 & 5.5, Firefox 1.5, Opera 8.5 (see known issues) & 9.0b

+ * 			MAC: Camino 1.0, Firefox 1.5, Safari 2.0

+ * 

+ * Requires:

+ * 		- Prototype v. 1.5.0_rc0 > (as packaged with Scriptaculous 1.6.1)

+ * 		- Scriptaculous v. 1.6.1 > modules: builder, dragdrop 

+ * 		

+ * 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 the error 

+ *        that the forceReRender() method fixes for IE 6, i.e. IE 5.5 is not redrawing the box properly.

+ * 

+ * 		- Lack of CSS opacity support in Opera before version 9 mean we disable those style rules, these 

+ * 		  could be fixed by using PNGs with transparency if Opera 8.5 support is high priority for you

+ * 

+ * 		- Marching ants keep reloading in IE <6 (not tested in IE7), it is a known issue in IE and I have 

+ *        found no viable workarounds that can be included in the release. If this really is an issue for you

+ *        either try this post: http://mir.aculo.us/articles/2005/08/28/internet-explorer-and-ajax-image-caching-woes

+ *        or uncomment the 'FIX MARCHING ANTS IN IE' rules in the CSS file

+ *		

+ *		- 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 (maybe Mac browsers too)

+ *		  I'm not sure why yet.

+ * 

+ * Usage:

+ * 		See Cropper.Img & Cropper.ImgWithPreview for usage details

+ * 

+ * Changelog:

+ * v1.2.0 - 2006-10-30

+ * 		+ Added id to the preview image element using 'imgCrop_[originalImageID]'

+ *      * #00001 - Fixed bug: Doesn't account for scroll offsets

+ *      * #00009 - Fixed bug: Placing the cropper inside differently positioned elements causes incorrect co-ordinates and display

+ *      * #00013 - Fixed bug: I-bar cursor appears on drag plane

+ *      * #00014 - Fixed bug: If ID for image tag is not found in document script throws error

+ *      * Fixed bug with drag start co-ordinates if wrapper element has moved in browser (e.g. dragged to a new position)

+ *      * Fixed bug with drag start co-ordinates if image contained in a wrapper with scrolling - this may be buggy if image 

+ * 		  has other ancestors with scrolling applied (except the body)

+ *      * #00015 - Fixed bug: When cropper removed and then reapplied onEndCrop callback gets called multiple times, solution suggestion from Bill Smith

+ *      * Various speed increases & code cleanup which meant improved performance in Mac - which allowed removal of different overlay methods for

+ *        IE and all other browsers, which led to a fix for:

+ * 		* #00010 - Fixed bug: Select area doesn't adhere to image size when image resized using img attributes

+ *      - #00006 - Removed default behaviour of automatically setting a ratio when both min width & height passed, the ratioDimensions must be passed in

+ * 		+ #00005 - Added ability to set maximum crop dimensions, if both min & max set as the same value then we'll get a fixed cropper size on the axes as appropriate

+ *        and the resize handles will not be displayed as appropriate

+ * 		* Switched keydown for keypress for moving select area with cursor keys (makes for nicer action) - doesn't appear to work in Safari

+ * 

+ * v1.1.3 - 2006-08-21

+ * 		* Fixed wrong cursor on western handle in CSS

+ * 		+ #00008 & #00003 - Added feature: Allow to set dimensions & position for cropper on load

+ *      * #00002 - Fixed bug: Pressing 'remove cropper' twice removes image in IE

+ * 

+ * v1.1.2 - 2006-06-09

+ * 		* Fixed bugs with ratios when GCD is low (patch submitted by Andy Skelton)

+ * 

+ * v1.1.1 - 2006-06-03

+ * 		* Fixed bug with rendering issues fix in IE 5.5

+ * 		* Fixed bug with endCrop callback issues once cropper had been removed & reset in IE

+ * 

+ * v1.1.0 - 2006-06-02

+ * 		* Fixed bug with IE constantly trying to reload select area background image

+ * 		* Applied more robust fix to Safari & IE rendering issues

+ * 		+ Added method to reset parameters - useful for when dynamically changing img cropper attached to

+ * 		+ Added method to remove cropper from image

+ * 

+ * v1.0.0 - 2006-05-18 

+ * 		+ Initial verison

+ * 	@param obj Optional options:

+ * 		- ratioDim obj 

+ * 			The pixel dimensions to apply as a restrictive ratio, with properties x & y

+ * 

+ * 		- minWidth int 

+ * 			The minimum width for the select area in pixels

+ * 

+ * 		- minHeight	int 

+ * 			The mimimum height for the select area in pixels

+ * 

+ * 		- maxWidth int

+ * 			The maximum width for the select areas in pixels (if both minWidth & maxWidth set to same the width of the cropper will be fixed)

+ * 

+ * 		- maxHeight int

+ *			The maximum height for the select areas in pixels (if both minHeight & maxHeight set to same the height of the cropper will be fixed)

+ * 

+ * 		- displayOnInit int

+// 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 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
