Detailed explanation-1: -Raster graphics are bitmaps. A bitmap is a grid of individual pixels that collectively compose an image. Raster graphics render images as a collection of countless tiny squares. Each square, or pixel, is coded in a specific hue or shade.
Detailed explanation-2: -What is a raster file? Raster files are images built from pixels-tiny color squares that, in great quantity, can form highly detailed images such as photographs. The more pixels an image has, the higher quality it will be, and vice versa.
Detailed explanation-3: -Raster images are also known as “bitmapped images". A Raster image is made up of pixels and the clarity depends on the resolution and size that it’s printed at.
Detailed explanation-4: -The name derives from the early CRT video technology, which would “paint” an image on a screen line by line by magnetically steering a focused electron beam across a fluorescent viewing surface. This process of building an image was known as a Raster Scan, and the resulting pattern-or picture-was known as a Raster.
