This is a format used for storing clipart images for working with CorelDRAW vector imaging. It’s used for entering separate, prepared graphical elements into a vector graphics design. It’s used as a blank template and is distributed in the form of millions of prepared cliparts which can compliment your own design.
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.
