The only person who can tell you the correct answer is the pressperson who will be printing the final job. GUIs have many advantages and some disadvantages. Neither do GUIs automatically promote good user interface design. Graphical user interfaces employ visual metaphors, in which objects drawn on the computer’s screen mimic in some way the behaviour of real objects, and manipulating the screen object controls part of the program. Through an associated technique, called bump mapping, the appearance of the texture can be improved still further. When you select it, a set of handles, little black squares, appear on or around the object (compare marquee). Computer graphics is the computational creation and manipulation of visual data. Vector images can easily be rotated and scaled to different sizes with no loss of quality, the computer simply multiplying the endpoint coordinates by a suitable factor. So you can choose to view these images in low resolution while you are working, just so you can move around the screen faster. 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. 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. A duotone (or tritone or quadtone) does not refer to the use of spot color for the second color; that is, if you take a photograph and color the lady’s dress pink, that’s not a duotone, even though there are two colors in the image. You may want to add more memory, especially if you plan to create and use complex graphic or photographic images. Since a computer can ultimately deal only with binary numbers, pictures have to be DIGITIZED (reduced to lists of numbers) in order to be stored, processed or displayed. The dot pitch helps determine how sharp the image looks, independent of the, A dot pitch of .28 mm or smaller is ideal for 14- or 15-inch monitors; a dot pitch of .31mm or less for 17- to 20-inch monitors. Some graphics are just low-resolution to begin with, such as graphics made in the paint file format at 72 dots per inch. (This is very different from bitmapped graphics, in which the image is mapped to the pixels on the screen, dot by dot. 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. To produce a textured surface using the techniques discussed would require creating an excessive number of surface pieces that follow all of the complexities of the texture. Grayscale monitors can display different shades of gray, rather than imitating the different shades with combinations of black and white dots. In lower resolution, 320x 200 pixels, the screen can show up to 256 colors at once. Resolution, in pixels, is determined by the video circuitry in your. The main types of graphics packages are painting, drawing, photo editing and CAD. The speed with which the beam travels horizontally and vertically (the horizontal and vertical “scan frequencies”), must match the synchronizing signals from the computer’s video circuits. These specifications are much better than the older video adapter standards, the, Unlike EGA and CGA monitors, VGA monitors are, When you’re shopping for a VGA monitor, keep several points in mind. The following are also considered graphics applications. By dragging the handles, you can change the size or shape of the object or the curviness of any curved lines. Pictures on a computer display or the process of creating pictures on a computer display. They work on the principle of electroluminescence, which refers to substances that glow when you apply electricity. Texture mapping is a technique used to paint scanned images of a texture onto the object being modeled. Presentation graphics software: Lets you create bar charts, pie charts, graphics, and other types of images for slide shows and reports. Providing software support for the plethora of different makes of adapter has become an onerous task for software manufacturers. Photoshopâ¢ Photoshop is a piece of software for users such as graphics designers to edit photos or images.â¢ Photoshop is incorporated with Adobe Web Premium CS5. Graphics software The range of pictures, drawings and images which can be produced by a computer are called graphics. The lower the resolution, the less information there is in a given amount of space (in a square inch, for instance). Three common applications are graphic user interface (GUI), computer-aided design (CAD), and computer games. But “monitor” encompasses the whole piece of equipment, rather than just the screen part that you look at. Most Macintosh people use the terms object-oriented and bitmapped rather than vector and raster. When you buy, be sure your monitor’s range of scan frequencies matches all the adapters you may use it with. Variants of these GUI objects are used to control programs under Microsoft Windows, Apple’s MacOS, and on UNIX systems that have a windowing system such as Motif or KDE installed. They use less power than incandescent bulbs and last over 100,000 hours. The resulting image will appear to be faceted, with ridges running along the boundaries of the pieces that make up an object. LEDs were used in digital watches, but now all digital watches use LCDs because LCD stakes less power. Vector graphics are stored in the computer as a set of mathematical formulas describing the shapes that make up each image. When you’re shopping for a VGA monitor, keep several points in mind. Vector and bitmapped representations have complementary strengths and weaknesses. And, by the way, multiscan monitors are more expensive than fixed-scan rate monitors. On the deficit side, GUIs require far more computing resources than older systems. These proved too expensive and too radical for commercial exploitation, but it was following a visit to PARC by Steve Jobs in the early 1980s that Apple released the LISA, the first commercial GUI computer, and later the more successful MACINTOSH. You should also insist on a variable frequency monitor, one that can match any frequency within those ranges, rather than one that simply operates at several different but fixed frequencies.
