Answer-Following are the differences between vector and raster graphics- 1. Raster or Bitmap images are resolution dependent because of this its not possible to increase or decrease their size without sacrificing on image quality. While vector based image are not dependent on resolution. The size of vector image image can be increased or decreased without affecting image quality. Raster or bitmap images are always rectangular in shape, Vector image, however, can have any shape.
Question-5 What is scaling in computer graphics? Answer- In computer graphic, image scaling is the process of resizing a digital image.
Question-6 What are the hardware devices used for computer graphics? Answer- Features of inkjet printers are- 1. They can print 2 to 4 pages per minute.
Therefor better print quality is achieved. The operating cost is very low. The only part that requires replacement is ink cartridge.
Four colors cyan, yellow, magenta, black are available. Question-8 What are the advantages of electrostatic plotters? Answer- Following are the advantages of electrostatic plotters- 1. They are faster then pen plotters and very high quality printers. Recent electrostatic plotters includes a scan conversion capability.
They make multiple passes over the paper to plot color picture. Question-9 What is meant by scan code? Answer- When a key is pressed on the keyboard, the keyboard controller places a code carry to the key pressed in to the part of the memory called as the keyboard buffer. This code is called as scan code. Question Define Random and Raster scan displays?
Answer- Random scan is a method in which display is made by electronic beam, which is directed only to the points or parts of the screen where picture is to be drawn. In , Ivan Sutherland invented Sketchpad , an innovative program that influenced alternative forms of interaction with computers. Douglas T. Ross of MIT developed an advanced compiler language for graphics programming.
Coons , also at MIT, and J. Ferguson at Boeing , began work in sculptured surfaces. In the s, artists and graphic designers began to see the personal computer, particularly the Commodore Amiga and Macintosh , as a serious design tool, one that could save time and draw more accurately than other methods.
The Macintosh remains one of the most popular tools for computer graphics in graphic design studios and businesses. Modern computer systems, dating from the s and onwards, often use a graphical user interface GUI to present data and information with symbols, icons, and pictures, rather than text. Graphics are one of the five key elements of multimedia technology.
In , Quake , one of the first fully 3D games , was released. In , Toy Story , the first full-length computer-generated animation film, was released in cinemas.
Since then, computer graphics have become more accurate and detailed, due to more advanced computers and better 3D modeling software applications, such as Maya , 3D Studio Max , and Cinema 4D. Another use of computer graphics is screensavers , originally intended to prevent the layout of much-used GUIs from 'burning into' the computer screen.
They have since evolved into true pieces of art, their practical purpose obsolete; modern screens are not susceptible to such burn in artifacts. Web graphics[ edit ] In the s, Internet speeds increased, and Internet browsers capable of viewing images were released, the first being Mosaic. Websites began to use the GIF format to display small graphics, such as banners, advertisements, and navigation buttons, on web pages.
SVG, and to some extent VML , support in some modern web browsers have made it possible to display vector graphics that are clear at any size. Plugins expand the web browser functions to display animated, interactive and 3-D graphics contained within file formats such as SWF and X3D.
This is because MS Paint is a drawing package and not a graphics package. Numerous platforms and websites have been created to cater to web graphics artists and to host their communities.
A growing number of people use create internet forum signatures—generally appearing after a user's post—and other digital artwork, such as photo manipulations and large graphics. With computer games' developers creating their own communities around their products, many more websites are being developed to offer graphics for the fans and to enable them to show their appreciation of such games in their own gaming profiles.
Uses[ edit ] Graphics are visual elements often used to point readers and viewers to particular information. They are also used to supplement text in an effort to aid readers in their understanding of a particular concept or make the concept more clear or interesting.
Popular magazines , such as TIME , Wired and Newsweek , usually contain graphic material in abundance to attract readers, unlike the majority of scholarly journals. In computing, they are used to create a graphical interface for the user; and graphics are one of the five key elements of multimedia technology. Graphics are among the primary ways of advertising the sale of goods or services.
Business[ edit ] Graphics are commonly used in business and economics to create financial charts and tables. The term Business Graphics came into use in the late s, when personal computers became capable of drawing graphs and charts instead of using a tabular format. Business Graphics can be used to highlight changes over a period of time.
