Raster graphics:
The picture or image that raster graphics creates is entered 'as file and data'.
The Pictures are of two types;

Raster Graphics are created on the basis of PIXELS.
The photos taken by the camera and the photos scanned by a scanner are of the raster type. When we enlarge this type of photo, we could see the pictures as rectangular layers or grids.
