Define vector graphic and bitmap graphic, and explain the characteristics of each.

What will be an ideal response?

A vector graphic is a mathematically calculated object composed of anchor points and straight or curved line segments, which collectively form a path. You can fill a path with a color, gradient, or pattern and outline it with a line known as a stroke. Vector graphics appear smooth, which makes them perfect for illustrations. Because they retain their appearance regardless of how you edit them, vector graphics offer far more flexibility than bitmap images. They keep their sharp, crisp-looking edges no matter how much you enlarge them.

A bitmap graphic displays a picture image as a matrix of dots, or pixels, on a grid. A pixel is the smallest square of color used to display an image on a computer screen. This is why most of the photographs and other images on a web page are bitmap images (also known as raster images). Pixels allow your computer screen to depict colors realistically in a photographic image. A bitmap image consists of a finite number of pixels. Therefore, when you resize the image, the existing pixels are stretched over a larger area, which causes distortion and loss of image quality.
