(a) are composed of a grid of pixels, with the resolution of the image defined by pixels per inch (PPI) or dots per inch (DPI). Since the resolution is defined by the number of pixels and dimensions, scaling the image beyond the original dimensions will result in a loss of quality, often referred to as pixelation. (b) s created by a mathematical formula using points and paths and can be scaled without losing quality.
What is a benefit of using vector image formats?
They are always larger in file size than raster images.
