What is the primary difference between raster and vector images?

The primary difference between raster and vector images centers around how they are created and how they handle resizing. Raster images are built from a grid of individual pixels, meaning they are resolution-dependent. When a raster image is resized, especially if it is enlarged, the individual pixels become more visible, and this can lead to a loss of quality, resulting in a blurry or pixelated appearance.

In contrast, vector images are composed of paths defined by mathematical formulas, which means they can be scaled infinitely without any loss of quality. This characteristic allows vector images to maintain sharpness and clarity regardless of their size, a fundamental reason why they are favored for designs that require flexibility, such as logos and illustrations.

The other answer choices highlight properties that do not accurately represent the essential nature of raster and vector images. For instance, raster images are not resolution-independent, and vector images are not exclusively limited to typography. Understanding these differences is crucial for making informed decisions about which type of image to use in various digital design applications.
