What is the primary advantage of using raster images?

The primary advantage of using raster images lies in their ability to capture and represent detailed color information. Raster images, which are composed of a grid of pixels, can display a vast spectrum of colors and subtle variations. This capability is particularly beneficial for images with complex color details, such as photographs and detailed artwork.

Each pixel in a raster image contributes to the overall image, allowing for intricate, high-quality visuals that can express gradients, shadows, and a range of textures effectively. While other formats may boast advantages like scalability or smaller file sizes, they often lack the same level of detail and color depth that raster images offer, particularly in applications where precise color representation is essential.
