What is the difference between a vector and it-map graphic?
In vector graphics the objects contained in the file are being stored as mathematical equations, so-called vectors. Vector files are usually plain text files, and therefore the compression is much more efficient than in bitmaps, because it is not necessary to store each pixel – only the mathematical description of the object(s). Bitmaps store the image data as so-called ‘pixels’ [short for ‘picture element’]. The color information is either being stored in a color palette, or together with each pixel.
