We are using the Image Uploader component to select multiple files for bulk upload. One of the requirements is to allow users to perform basic editing of photos during upload. The operations required are cropping and rotating. Now these have to be applied over the images whih has already been selected in the Image Upload List pane in a three pane view of the Image Uploader. So these Image Processing operations will have to be performed at the client side without page postback. Can you tell me if this is possible. Looking at the demos and the API it looks like this is primarily a server side component. Though probably there is a client side library available using remote scripting techniques(AJAX). I did not get enough time to go deep into this but probably not all image processing operations are supported at client side. Can you provide me with some source code on how to implement cropping and rotation at client side with server side posts.

Image Uploader supports three basic imaging operations on the client-side: rotate, resize, and adding watermark. Unfortunatey crop is not supported.

In your case you can implement the required functionality in the following way:
  1. Resize and rotate operations are performed on the client using Image Uploader.
  2. Crop is applied on the server using Graphics Mill.
The article Resizing and Rotating Images will give you the quick outlook how to implement imaging operations with Image Uploader.
Sincerely yours,
Dmitry Sevostyanov
