Vector Graphics

Vector graphics are a form of computer graphics that use a mathematical formula to construct the image, storing the lines, shapes and colours in the math formula.


Each computer display is made up of pixels, images are built up form these individual cells.  Naturally the smaller and closer the pixels are together the higher the image quality, but the larger the file size becomes.  However if the number of pixels is kept constant, when the image is enlarged it becomes grainy (literately 'pixellated'), the human eye can begin to pick out individual square pixels.


Vector graphics programs use the files math formula to construct the best possible screen image, based on the current resolution.  This way the image can be scaled to any size required limited by only the computers resolution display.  Vector graphics are often the favourable practice when it comes to an online environment.
