PRESENTATION GRAPHICS

Presentation graphics programs, used to make computer-based presentations to others, represent a fast-growing segment of today’s computer applications. These programs are used in business and education or by anyone else who needs to make presentations to groups.

Although analysis graphics software has been used in business for some time to illustrate numerical data, it is only recently that the new category of presentation graphics software has emerged. Whereas analysis graphics software allows the user to create a variety of charts and graphs for display on the computer screen or for output to a printer, presentation graphics software provides a way to create high-quality presentations for delivery by computer. Often special projection devices are used to display a larger version of the graphics that appear on the computer’s screen.

Business people are constantly involved in presenting a variety of information to different groups of people, whether it is in meetings of in-house personnel or a sales pitch to a customer. Presentation graphics software provides a way to communicate this type of information in a cohesive format. These programs generally provide a set of easy-to use options that can be used to create a series of computer-generated “slides”, screens full of information that can be presented in sequence by the computer.

Usually, the user can select from a variety of colored borders and backgrounds that help to enliven the overall look of the presentation. Graphics can also be imported from other programs. For example, charts and graphs created software can be imported.

Full-color, three-dimensional photographs which have been scanned (digitized) can also be added to the presentation. Text can be entered for titles objects. Some of today’s presentation graphics programs also provide a way to import digitized video images, animation, and sound.

Most presentation graphics software provides a variety of output options. Even if the presentation is to be presented on a room-sized screen using an LCD projector or a large screen monitor, the presenter may want to output certain information to a printer to create handouts for the group.

Through the use of special devices and media, the presentation screens can be transferred to 35 mm slides, to transparencies, or to video tape. In addition, some of today’s presentation packages include features found in creative paint or draw programs, such as tools to draw geometric shapes and lines of different styles and thickness. These graphics tools can be used to create simple diagrams or line drawings to add special emphasis to certain aspects of the presentation.
