Each of these objects (except text) may be drawn using a "pen", which can have any rectangular dimensions, pattern or color. Note that, because the pen is rectangular and axis-aligned, diagonal lines will end up thicker than horizontal or vertical ones. Shapes may be drawn filled or framed, using any pattern or color. A filled Arc forms a wedge. Text may be drawn in any installed font, in a variety of stylistic variations, and at any size and color. Depending on how the selected font is stored, text can be scaled in a variety of ways - TrueType fonts will scale smoothly to any size, whereas bitmap fonts do not usually scale well.
