I design emoticons, and often I need to resize things. However, this usually needs to be done without anti-aliasing. I can't find anywhere to do this.
It's kind of backward, as it's actually harder for a program to use anti-aliasing than not. It also means I need to spend lots of time hand-pixelling everything twice as large.
I'd especially prefer a way that this can be done within Photoshop CS3, though it's not required.
