Vector graphics use geometric primitives (points, lines,
curves and shapes or polygon) to create an image on a digital device. Vectors,
which can also be called paths or strokes, are lead through certain locations
called control points in order to create the image. The central points have a permanent
position on the x and y axes and are assigned a colour, a shape, a thickness
and also a fill. One of the main advantages of a vector image is that it can be
scaled to a large size and will not pixelate. Below is an example of how an object can be scaled and not lose its quality.
Vector images can be generated using a number of different
software such as Adobe Illustrator, Adobe Flash and CorelDRAW. As photographic
imagery are raster images (include pixels), therefore vector file extension do
not support them. There is a large variety of file formats that a vector image
can be created in, such as .SVG, .EPS, .FLA, .AI, .CDR, .WMF, and .DRW.
