Raster graphics


Written By: Ehsan Jahandarpour

In computer graphics and digital photography, a raster graphic represents a two-dimensional image as a rectangular matrix or grid of square pixels, viewable via a computer display, paper, or other display medium. A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats.
