We need an image editing module.
We need to take an image and FILTER A RADIAL region of the image.
The radial region is selected with mouse click and it's size [radix] should be selected through a Slider.
The image will be loaded from the disk [with browse] and there should be an option to save them to JPEG or PNG back to the disk.
I've attached 2 photos to give you an idea of what I want.
If you can deliver this and make a good job, more image processing modules in FLEX and ActionScript3 may come.
