Computer Graphics There are basically two types of computer graphic, bitmapped and vector/structured . Bitmapped graphics are images that are mapped to the monitor or screen . The screen is made up of tiny dots called pixels . These dots can display various colours depending on the type of computer hardware and software you have.

Computer Graphics Using shades of red, green and blue (RGB) an image can be displayed on the screen by mapping different colours to the screen in different sequences. Vector graphics use objects created from mathematical formulas to represent things like lines, curves, fills, line thickness, etc. to create the image.

Computer Graphics Some of the structured formats are .ai, .cmx, .eps, .wpg, .cgm and a host of others. Bitmapped graphics can be created and modified in a paint program and vector or structured graphics can be created and modified in a draw program. The main tools in a graphics program allow you to select a section of a picture, erase part of a picture, fill a defined area, select a colour, magnify a section, draw free hand, draw with various tools such as a straight line; a curved line; a rectangle; an oval; and a polygon. You can also modify a drawing by changing the size, colour, placement, and, depending on the program, hundreds of other modification.

Graphic Images, Sounds & Animation Graphics Computer graphics are anything that can be displayed on the screen except the text and sometimes even text falls into the graphics category if it is save in a graphics format .

Computer Graphics Each type of graphic has it's own advantages and disadvantages. Older versions of HTML were only able to recognizes bitmapped graphics so most graphics created for the Internet, using standard HTML , are created or converted to a bitmap format . The newest version of HTML or XHTML is able to display vector graphics but not all browsers are able to display these graphics.

Graphic Images Within each of the two main types there are dozens of different formats. Graphics formats are distinguished by their filename extensions. The three main bitmapped format graphics used on the Internet are .gif, .jpeg (.jpg) and .png. There are many others including .bmp, .tiff (.tif), .pcx, .ppm, .tga and a host of others.

Sound Other formats are Audio Visual Interleave's .avi , the before mentioned mpg , Microsoft's Media Player .wmv , Apple's Quick Time .qt , .aif(*) & .mov , RealNetwork's RealVideo .rm(*) , Macromedia's Flash creates Shockwave .swf , and JavaScript as well as various others.

Sound Moving Picture Experts Group (MPEG) or .mpg is multimedia format that is an attempt to create a standardization among the various formats available. MPEG has made it possible to place audio content on the website without having it sound tiny and hollow or taking an extreme amount of time to download. There are many different formats for sound including; Microsoft's .wav, Sun's .au & .snd, RealNetwork's RealAudio , .ra(*), and various others.

Sound You may have heard .mid files play when visiting various websites. Musical Instruments Digital Interface (MIDI) files are basically sound tracks which use a collection of sounds contained in the .mid file to play a tune. To create a sound file you will need an audio program. You can then record with a microphone or off of a prerecorded medium. Your computer will need to have a sound card properly installed and a speaker to hear your recording. You can save the sound file to play back later.

Using MultiMedia at Business Exciting presentations are used to grab and keep attention in advertising . Business to business, and interoffice communications are often developed by creative services firms for advanced multimedia presentations beyond simple slide shows to sell ideas or liven-up training. Commercial multimedia developers may be hired to design for governmental services and nonprofit services applications as well.

Using MutiMedia in Education In Education , multimedia is used to produce computer-based training courses (popularly called CBTs) and reference books like encyclopedia A CBT lets the user go through a series of presentations, text about a particular topic, and associated illustrations in various information formats. Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment Media convergence

Using MutiMedia in Entertainment In addition, multimedia is heavily used in the entertainment industry, especially to develop special effects in movies and animations Multimedia games are a popular pastime and are software programs available either as CD-ROMs or online. Some video games also use multimedia features. Multimedia applications that allow users to actively participate instead of just sitting by as passive recipients of information are called Interactive Multimedia

Animation With the advent of faster computers comes animation. A GIF animation is a series of separate images or frames that display one after the other to give the impression of movement.
