HISTORY OF GRAPHICS

1. BASIC TYPES OF GRAPHICS

There are two main types of graphics namely:  

1.  Vector graphics, and 

2.  Bitmaps. 

Vector Graphics 

 Vector graphics (Mukhopadhyay & Chattopadhyay, 2007) are those which can be created straightaway on a computer without engaging a third party system or facilitation. For instance, you can type texts, draw lines, curves, shapes and fill them with some color without the use of any third party gadget or appliance. These are generally referred to as graphic primitives and they, especially the shapes, are generated from a set of programmed algorithms that determine their positions, length as well as their directions.

Bitmaps:

Bitmaps or rasterised images (as technical persons and engineers prefer to call them) cannot be imputed into your system without the use of an application independent of your computer. Unlike vector graphics which are generated from a set of algorithms that determine their position, direction, weight and length, bitmaps consist of tiny squareshaped picture elements,  which are called pixels – a reason why bitmaps are also called pixilated graphics. Each pixel is the small dot that a computer can recognise. Each pixel maps a location in an image and has numerical color forms, each with a value. The photograph you take with your camera is a classic example of a bitmap graphic
