A raster image is a type of computerized image that consists of row after row of tiny dots (pixels). If you have a scanner and scanner software, you can create a raster image by scanning a paper map. After you scan a map image and store the image in a file, you can display the file using MapInfo Pro.
In contrast, vector images contain coordinate-based data structures represented by x and y coordinates (most of MapInfo Pro's data is in vector format).
