Vector Graphics

Vector Graphics is the use of polygons to represent images in computers graphics.

Vector graphics are based on vectors, which lead through positions 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, furthur, each path may be assigned a stroke color, shape, curve, thickness, and fill.

Differentiating Vector and Bitmap image after zooming.

Vector based images are not made up of a specific number of dots,they can be scaled to a larger size and not lose any image quality.Raster images are made of grid of pixels.

Vector image without pixels and Raster images with pixels.

If you blow up a Raster Image, it will blocky or "pixelated".When you blow up a Vector graphic Image, the edges of each object within the graphic stay smooth and clean.

Raster Image blurred and Vector Image still smooth after magnification.

Examples of Bitmap images are .jpeg, .gif, .bmp and Vector Images are .ai, .eps, .svg, .drw etc..,
