If you want to know what this does and the title of this review doesn't help you, look up "The Rasterbator". This takes your image and puts a halftone screen of top of it for printing at large sizes.

Useful App. To answer the previous review 'What does it do?'. Just open the app and load a picture, or any file, Viola! It's pixelated!

I cannot get the software to open any type of image extension. And whan attempting to use support, it loads a website that offers no support about this software. Uninstalled.

I downloaded the app on my mac and the only thing that popped up when I tried to use it was the white box in the main photo for the app.
