ImageCropper is a free component written by Paul Whitelock for Adobe Flex that allows an image to be cropped by adjusting the position and dimensions of a cropping rectangle that overlays the image.

ImageCropper may be configured to constrain the cropping to an aspect ratio. For example, defining a cropping rectangle with a width of 200 pixels and a height of 100 pixels and then enabling the aspect ratio constraint will result in the cropping rectangle maintaining a 2:1 aspect ratio as it is resized.

ImageCropper works with a BitmapData Object or a URL that points to an external image. There are also lots of options for customizing the look of this component, and since the souce code is included this makes a great base for extending it into a custom component for your site.

Well done Paul!
