As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be.įor example, if we scale a raster image to enlarge it, without changing resolution, it will lose quality and look blurry or pixilated. The number of pixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. Since raster images are pixel based, they are resolution dependent. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image. These are the types of images that are produced when scanning or photographing an object. Raster (or bitmap) images are generally what you think about when thinking of images.
