| Most images you see on your computer screen are raster graphics. Pictures found on the Web and photos you import from your digital camera are raster graphics. They are made up of grid of pixels, commonly referred to as a bitmap. The larger the image, the more disk space the image file will take up. For example, a 640 x 480 image requires information to be stored for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel digital camera) needs to store information for a whopping 6,291,456 pixels. |

| Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a triangle, or a curvy shape. These paths can be used to create simple drawings or complex diagrams. Paths are even used to define the characters of specific typefaces. |

| An image in meta format is a combination of both of the two basic formats; vector and raster format. Examples of meta images are scanned photos in which you want to include describing text/numbers, graphics (eg arrows) or both. In some cases you might want to put describing numbers, text and arrows in these images. Both text and arrows should be saved as vector information and not as raster to keep the good quality but the photos still needs to be in a raster format. |
