Vector Images

Bitmap images, sometimes also called raster images, have their data organized in horizontal rows of pixels for convenient dispatch to raster-scan devices. Devices and display software also exist that can directly display any line, if given an exact specification of the line. An example is a straight line defined by its two endpoints. Such a line is sometimes called a vector, and an image file whose data is specified exclusively in terms of vectors is called a vector image file. Other example of the vector element is a text. The text is defined by a set of parameters: text string itself, font type face, font width and height, color, position, base line angle and some other.
