Bitmap vs. Vector

Today, I learned the difference between bitmap and vector artwork and the benefits of vector artwork.

Vector graphics are computer graphics images that are defined in terms of points on a Cartesian plane, which are connected by lines and curves to form polygons and other shapes. As a result, the finished look is crisp and clear, making it able to be as small as a business or something as large as a billboard without having to worry about degrading quality. When the size is increased or decreased, the vector points are recalculated and connected, maintaining a clean image.

On the other hand, bitmap graphics is a digital image composed of a matrix of dots which its images are constructed of little squares of color information called pixels. They traditionally lend themselves to images with great tonal range, like photographs. However, they’re only limited to the amount image. If you increase the size of the image, the pixels spread out, resulting in a lower-quality image.
