In continuation with our constant quest to acquaint you better with Photoshop concepts, we decided to give you a feeler about different concepts of computer graphics. To begin with there are two types of computer graphics: raster graphics and vector graphics.

a)      Raster graphics: These are images which are composed of tiles, pixels or in layman’s term dots. They use a grid of individual pixels where each pixel can be a different color or shade. Now when they are enlarged these pixels or dots give a stair step-like jagged appearance. This can be partially overcome with the use of “anti-aliasing”. Anti-aliasing is the application of subtle transitions in the pixels along the edges of images to minimize the jagged effect. All kind of monitor screens, dot matrix, inkjet, and laser printers, and scanners are raster image devices. They are also called bitmap images because it contains information that is directly mapped to the display grid. These are best used for photographs and images with subtle shading.

b)      Vector graphics: Vector graphics use mathematical relationships such as points, lines , curves, and shapes or polygon between points and the paths connecting them to describe an image. They are made up of paths. They are also known as rasterized images. The good thing about them is that they are scalable and their size can be changed as desired without hampering the quality of these images. This makes them a more favored format for corporate logos or other imagery that requires frequent resizing and a crisp appearance. They are mainly used in handbooks or instruction manuals wherein a stylized, rather than a realistic, result is required.

When we try to compare both the images we find vector images handier as they are lighter than the raster images. more…
