An image composed of pixels is called?

• A. Vector Graphic
• B. Raster Image
• C. Bitmap Image
• D. Photograph

Answer: (B)

Images composed of pixels are raster images. A raster image is built from a grid of tiny picture elements called pixels, each with its own color. When you enlarge it, you can see the individual pixels, which is why it’s described as pixel-based. In contrast, vector graphics describe shapes and lines with mathematical data, so they can scale up without losing sharpness. Bitmap is a term that refers to a specific type of raster image, but the general category for pixel-based images is raster. A photograph is typically a raster image, but the broad classification you’re looking for is raster.
