The toolbar includes a number of basic and familiar tools, such as erase, magnifier, and pencil. It also has select, free-form select, color pick, and color fill. Free-form select designates irregularly-shaped objects in your picture, and pick color helps you set a foreground or background color based on the color you pick. Paint also includes brushes of various styles, lines of various thickness, a large collection of shapes, background transparency options, and a full color palette. You can customize colors or pick a specific color using the color pick tool. Size options can be very helpful. In Paint versions after Windows XP, you can resize images after drawing them.
