Raster Graphics
Definition: Digital images composed of a grid of pixels, where each pixel contains color information.
Understanding Raster Graphics
Raster graphics (also called bitmap images) are digital images made up of a rectangular grid of pixels. Each pixel contains information about its color, and together they form a complete image. Common raster formats include JPEG, PNG, GIF, and BMP. Raster images are resolution-dependent, meaning they can become pixelated or blurry when scaled up beyond their original size. They're ideal for photographs and complex images with subtle color gradients.
