Which statement best describes vector graphics?

• A. They are encoded as a grid of colored squares
• B. They must be bitmap images to scale
• C. They are page layout elements only
• D. They are created with mathematical calculations and can be resized without loss of quality

Answer: (D)

Vector graphics are defined by mathematical calculations that describe shapes, lines, and curves rather than a fixed grid of colored pixels. Because they use geometry to render images, resizing simply recalculates those equations, giving you clean, sharp edges at any size without losing quality. This resolution-independence makes them ideal for logos, icons, and typography where crisp scalability is important. In contrast, raster (bitmap) images are built from a grid of pixels, so enlarging them can cause blurring or jagged edges. Vector graphics aren’t limited to page layout elements; they are editable at the shape and stroke level and can be saved in formats that preserve the mathematical description.
