Have you ever tried to playfully magnify your image using paint or some other image editor? I don’t know about you, but I have tried those. It looks as though your face or some of your body part have broken down to pieces. That’s funny! Do you know the reason behind the image looking so broken or gory? If no, well let’s discuss it now.

Normally an image captured by a camera will be saved as a raster type of image. .jpeg, .bmp, .jpg etc. refers to the extension of a bitmap image. Now, coming back to the question, why is it looking so rusty with less clarity? Well the argument that suits the answer for this question is, these raster images are based on grid of pixels arranged in an orderly manner. As these pixels are the smallest controllable elements on the screen, if magnified, it shows the distinct magnified image of each pixel. Thus, the clarity reduces and there is an increase in the size of each pixel.

To overcome this disadvantage in pixel technology, vector graphics are introduced. These vector graphics come with the file extensions namely .ai, .eps, .svg, etc and provide higher and better clarity of a magnified image. In vector graphic technology, instead of representing an image by a dot, they are defined by a specified path with an initiating and terminating point for each path. These paths may include basic mathematical figures like a square, a line, and a triangle or even closed paths like a circle or an ellipse. This technology allows designers to blow up small logos to a size equaling big billboards with non-pixelated image with smooth and clean edges. Really cool huh? Hats off to today’s enhanced technology, isn’t that right folks?
