> Opacity is an editor for screen graphics designed exclusively for
> Mac OS X. It makes it easy for graphic artists to design great
> looking images for icons, desktop applications, and the web.

> your graphics resolution independent. It's been designed from the
> ground up to make it easy to make gorgeous graphics at multiple
> resolutions.
>
> Opacity is a powerful tool for professional artists with all the
> features you'd expect, like vector objects, pixel editing, and live

> Opacity Express
>
> Opacity Express is a streamlined, more affordable version of
> Opacity. It includes most of Opacity's innovative, powerful features
> at a much lower price. Best of all, if you decide you need to
> upgrade to Opacity, you can at any time for the difference in price.

> What It's Not
>
> The things that Opacity doesn't do were almost as important in
> creating it as the things it does do. By focusing on a very specific
> purpose (graphics for the screen), Opacity is easier to use and has
> specific features that wouldn't make sense if it tried to do
> everything. Here are some things it's not for:
>
> � Editing photos
>  � Creating prepress images
>  � Creating print graphics
>  � Legacy image formats
>  � Swiss army knife-style image editing
