This is a bitmap image format that was created by the MacPaint graphics program used on Apple Macintosh computers. The MAC format supported the display of only two colors, including a pattern palette. It was used by Macintosh graphics editors to store black-and-white graphics. The maximum image size was 576×720.

This format has the same color structure as RGB, but it includes an alpha channel that is used to display various levels of transparency. The transparency value is set from 0 to 1, where 1 corresponds to opacity. It is described using the CSS3 programming language.
