monitor with 16 colors (or gray scales, if the monitor is a monochrome monitor).
Although there are higher resolutions available (for example, Super VGA has a resolution of 800 x 600), Standard VGA can display very good images and comes
with most new computers.
Standard VGA requires a VGA board and a monitor capable of displaying VGA
graphics. A Standard VGA board comes with 256K of memory attached to the
board. This limits 640 x 480 VGA displays to 16 colors. Both the resolution and
the number of colors of display can be increased by increasing the memory on the
graphics board. For example, if this memory is increased to 512K, a resolution of
640 x 480 with 256 colors is possible. Similarly, if this memory is increased to 1
MB, resolutions of 800 x 600 or 1024 x 768 with 256 colors are possible. These
graphics are called extended graphics. Higher resolutions with more colors make
image displays noticeably better. But the computer system must have a monitor
capable of displaying such high-resolution images.
6. Laser printers are*most commonly used to output graphics in hard copy form.
7. Plotters are also used to output graphics in hard copy form.
Software Requirements for Graphics
In addition to the above listed devices, the following graphics processing
capabilities are highly desirable ii multimedia computer system for better
presentation and use of graphics information:
Painting or drawing software. This software allows the user to create
graphics from scratch by using a mouse and various simple objects such as lines,
circles, and polygons with various supporting colors. It also allows the user to
modify and enhance graphic images produced using a scanner or screen capture
software. All these features make this software very useful for creating desired
graphics in a multimedia application.
2. Screen capture software. Often we need to incorporate images from computer
screen displays in some document. Screen capture software packages are used in
such cases to capture the display of a computer screen as a graphic image....
