What is Vector Graphic?

Vector Graphic is the use of geometric shape made up of lines, boxes, circles, polygons and other shapes that can be mathematically expressed in angles, coordinates and distances. Vector graphics are based on vectors (also called paths), which lead through locations called control points or nodes. Each of these points has a definite position on the x and y axes of the work plane and determines the direction of the path; further, each path may be assigned a stroke color, shape thickness, and fill. These properties don’t increase the size of the vector graphics files in a substantial manner, as all information resides in the document’s structure, which describes solely how the vector should be drawn. Vector graphic can be magnified infinitely without loss of quality, while pixel-based graphics cannot. A vector file is sometimes called a geometric file. Most images created with tools such as Adobe Illustrator and CorelDraw are in the form of vector image files. Vector image files are easier to modify than raster image files.
