A
Vector image never pixelates, and this is because it isn't “made up of a grid
of pixels” (techterms.com.) Instead they consist of lines,points, polygons and
curves, which help indicate images graphically. Vector images are used instead
of raster images, like JPEGs, GIFs, TIFFs and BMP formats.
The
way that Vectors uses lines and curves is that they are “connected by points”
(absolutegraphix.co.uk), and once the points are connected up, they look like a
whole shape. Vector Images are also made from polygons which make up the
points, which are called “primitives,” this means that vector images are good
for typography and images for advertising so that no matter what platform you
view the image it will be clear and won’t pixelate, making it more professional.
The
file extension that vector images come as are EPS (Encapsulated PostScript), which
is a type of file that can include text as well images, that is created in
Adobe Illustrator. Another type of file format that is produced in Adobe
Illustrator is AI (Adobe Illustrator Artwork) and SVG (Scalable Vector
Graphics.)
