Definition of Vector Image

A vector image is thedigital image. It is made up of independent geometric objects such as: polygons, arcs, among others, and each of them will be defined by different mathematical attributes such as shape, color, position.

The Format that the vector image shows is totally different from that of raster graphics, made up of pixels.

The main goodness offered by images vector is that of being able to expand its size to piacere without suffering the scaling problem that raster graphics have.
They also allow you to move, stretch and even twist the images in a very simple way.

Between the geometric figures that apply, the following stand out: polygons, lines, polneas, Bezier curves, Bezigonos, ellipses and circles.

It should be noted that the use of this type of format has been extended to the generation of images in three dimensions, whether static or dynamic.

The most recurrent uses that these types of images receive are: graphics generation (they are used to create expandable logos and in the

design technical: CAD),language from description of documents (PostScript and PDF formats, unlike raster graphics, these allow viewing and printing without loss of resolution), video game (3D video games), Internet (they usually appear in open formats: VML and SVG or in proprietary format) and fonts (TrueType, PostScript and OpenType).

As the screen of all computers is physically composed of pixels, they are prepared to translate from graphic rasterized to vector graphic.
