Graphics are visual presentations on some surface such as a wall, canvas, computer screen, paper or stone to inform, illustrate or entertain. Examples are photographs, drawings, Line Art, graphs, diagrams, symbols, geometric designs, maps, engineering drawings, or other images which are not only text. Graphics is often used in combination with text and color.
Graphics can be functional or artistic. Graphics can be imaginary or representing something in the real world. The latter can be a recorded version, such as a photograph, or an interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may get blurred.
The following are also considered graphics applications :
In general, applications that support graphics require a powerful CPU and a large amount of memory. Many graphics applications—for example, computer animation systems—require more computing power than is available on personal computers and will run only on powerful workstations or specially designed graphics computers. This is true of all three-dimensional computer graphics applications. In addition to the CPU and memory, graphics software requires a graphics monitor and support for one of the many graphics standards. Most PC programs, for instance, require VGA graphics. If your computer does not have built-in support for a specific graphics system, you can insert a video adapter card. The quality of most graphics devices is determined by their resolution—how many points per square inch they can represent—and their color capabilities.
Computer graphics are any types of images created using any kind of computer. There is a vast amount of types of images a computer can create. Also, there are just as many ways of creating those images. Images created by computers can be very simple, such as lines and circles, or extremly complex such as fractals and complicated rendered animations.
- If you want to create your own computer graphics, no matter how simple or complex, you have to know a few things about computers, computer graphics, and how they work.
Web graphics
In the 1990s Internet speeds increased, and Internet browsers capable of viewing images were released, the first being Mosaic. Websites began to use the GIF format to distribute small graphics such as banners, advertisements and navigation buttons on web pages. Web graphics are useful in providing a truly graphical user interface to websites rather than plain text.
A program like MS Paint in Microsoft Windows can be used for beginners, and gradually more professional programs like Photoshop and Paint Shop Pro can give you more abilities but may be harder to use.
Numerous websites have been created to host communities for web graphics artists.
