Where image editing programs do not directly support the FPX format, files are created by downloading a plug-in from Live Picture. Overview A Vector graphic differs from a raster graphic in that its content is described by mathematical statements. The statements instruct a computer's drawing engine what to display on screen i.e. pixel information for a bitmap is not stored in the file and loaded into the display device as it is in the case of JPEG and GIF . Instead shapes and lines, their position and direction, colours and gradients are drawn. Vector graphics files contain instructions for the rasterisation of graphics as the statements arrive at the viewer's browser - 'on the fly'.
Vector graphics are resolution independent.
That is, they can be enlarged as much as required with no loss of quality as there is no raster type image to enlarge and pixelate. A vector graphic will always display at the best quality that the output device is set to. When printing out a vector graphic from a Web page it will print at the printer's optimum resolution i.e. without 'jaggies'. Until recently only proprietary formats such as Macromedia Flash or Apple's QuickTime have allowed Web designers to create and animate vector graphics for the Web. An SVG file is itself comprised of text, that is the drawing engine instructions within it are written in ordinary text and not the binary symbols 1 and 0.
