If the monitor uses 4 bits, there are 16 possible combinations of on and off, so there are 16 possible shades of gray. The most natural representation for a picture inside the computer is therefore just a list of the colours for each dot in the output; this is called a BITMAPPED representation. These include: WINDOWS, ICONS, pull down and pop-up MENUS, BUTTONS and button bars, check boxes, dialogues and tabbed property sheets. The succession of graphics adapter standards that IBM produced throughout the 1980s (CGA,EGA,VGA)both defined and confined the graphics capability of personal computers until the arrival of IBM-compatibles and the graphical Windows operating system, which spawned a whole industry manufacturing graphics adapters with higher capabilities. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that … 2. Presentation graphics is often called business graphics. The most common graphical display devices are the CATHODE RAY TUBE inside a monitor, and the PRINTER, both of which present pictures as two-dimensional arrays of dots. The superficial similarity between this use of dots in printing and the PIXELS that constitute, pixels actually vary in colour and intensity rather than size. The vertical frequency measures how fast the entire screen is “repainted,” and is also called the refresh rate. To select a graphical object in an object-oriented graphics program, you usually just click on the object with the pointer. Through an associated technique, called bump mapping, the appearance of the texture can be improved still further. Hiding 100 poorly-chosen commands behind the tabs of a property sheet is no better than hiding them among an old-fashioned menu hierarchy – the point is to reduce them to 5 more sensible ones. Those are LEDs. 10. The term came into use when there was still a distinction between computers that could display only text and those that could also display pictures. In addition to the software, CAD systems require a high-quality graphics monitor; a mouse, light pen, or digitizing tablet for drawing; and a special printer or plotter for printing design specifications. The quality of most graphics devices is determined by their resolution—how many pixels per square inch they can represent—and their color capabilities. 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. Color dithering smoothes out images by creating intermediate shades between two more extreme colors (called a. At a minimum, it should have a 50-75 Hz (hertz, times per second) vertical frequency and a 30-50 kHz (kilohertz) horizontal frequency. In a, A duotone (or tritone or quadtone) does not refer to the use of, The dot pitch of a color monitor measures the size of the tiny individual dots of phosphorescent material that coat the back side of the picture tube’s face. Presentation graphics software: Lets you create bar charts, pie charts, graphics, and other types of images for slide shows and reports. There are many software applications that enable you to create animations that you can display on a computer monitor. LEDs were used in digital watches, but now all digital watches use LCDs because LCD stakes less power. You can choose to print them in low resolution just so you get an idea of the look of the brochure without waiting to reproduce the entire high resolution images. A grayscale tries to approximate the continuous gray tone of photographs. A grayscale is also one variety of TIFF (tagged image file format). (GUI) An INTERACTIVE outer layer presented by a computer software product (for example an operating system) to make it easier to use by operating through pictures as well as words. LEDs are ordinary diodes (the most basic electronic component) that, due to their composition, happen to glow red, green, or amber when energized by a couple of volts. Iphoto• Iphoto is a software device that is only available in Mac computers. Objects maybe displayed in a wireframe outline form. It means by using a personal computer or workstation high-quality printed documents can be produced. On a piece of photographic film, such as the kind you use to shoot photographs, one side of the film is coated with a layer of chemicals called the emulsion. Neither do GUIs, On the Macintosh, some programs let you edit, On a piece of photographic film, such as the kind you use to shoot photographs, one side of the film is coated with a layer of chemicals called the, A typical black-and-white photograph uses only one color. A graphical user interface usesmenusandicons(pictorial representations) to choose commands, start applications, make changes to documents, store files, delete files, etc. (This is very different from bitmapped graphics, in which the image is mapped to the pixels on the screen, dot by dot. Monitor size is measured like a television, from one corner to the diagonally opposite corner. In lower resolution, 320x 200 pixels, the screen can show up to 256 colors at once.
