HTML5 Image cutout tool

We need a function to create a new image from an existing one. The function will be implemented to our product pages in admin panel to create different kind of product images. From the product editing page the tool must load a predefined image. Inside this image it shows a predefined cutout window. The user can move the cutout window to choose a good view inside the picture. When the User saves the cutout, this part of the image is saved on the server with predefined settings. Predefined settings should include everything from image location of loaded image over quality settings of saved images, as well as aspect ratio, size, default x- and y- location of the cutout. The user should have possibility to manipulate the cutout with the following settings: - Auto Beautify function - Manual sharpness - Manual light and contrast - Manual saturation See attached PDF File for Details and layout proposal. The Features shown in the attached PDF are required too. (For example multiple presets to choose from) The toolon must have proper manual/description, so that everybopdy with basic skills can implement it! The code must be well written and documentated for future develeopment! Final price bids only, all features required are listed here.
