A raster image, also known as a bitmap, is a digital image composed of a grid of pixels. Each pixel contains color information, and the overall arrangement of pixels creates the image. Raster images are resolution-dependent, meaning that their quality decreases when they are scaled up or down. They are best suited for photographs, detailed illustrations, and digital paintings, where intricate color variations and smooth gradients are essential. A vector image, on the other hand, is created using mathematical equations to define geometric shapes, lines, and curves. Vector images are resolution-independent, meaning they can be scaled up or down without losing quality. They are best suited for graphics that require clean lines, sharp edges, and scalability, such as logos, icons, typography, and illustrations with limited color schemes. In summary, raster images are ideal for capturing detailed color information, while vector images are best for scalable and sharp-edged graphics.
