Unformatted text preview: a word processor or a database file. The file (partly or fully) can be simply imported into the new document at the desired location instead of retyping the entire text again. If the imported file is large, it will result in enormous saving of time and effort required to prepare the new document. Similarly, text exporting feature is very useful in allowing other packages to use an existing document (partly or fully). Graphics Computer graphics deals with the generation, representation, manipulation and display of pictures with the aid of a computer. Graphics is an important component of multimedia because a picture is a powerful way to illustrate information. For example, in a multimedia application meant for educating small children, displaying the photograph of a horse along with its text description makes the illustration much more effective. Without the photograph, it will be very difficult to explain using only text how a horse looks like. Similarly, displaying the photograph of an employee, along with his/her name, address, sex, age, etc. from a company's database of employees, makes the employee information much more effective. Graphics Types The pictures used in computer graphics can be broadly classified into two types: 1. Line drawings. These are drawings and illustrations in the form of 2D and 3D pictures created from mathematical representation of simple objects like lines, circles, arcs, etc. Simple object types are used to create complex objects. For example, the picture of a chair can be drawn using lines and arcs. Numerical results obtained from computations can also be transformed to graphics forms like bar graphs or pie charts using simple objects. The area of computer graphics that deals with this type of pictures is known as generative graphics. Generative graphics is extensively used in creating illustrative diagrams. For example, most of the figures in this book have been created by using this technique. Another very important application of generative graphics is CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing). For example, n...
