What are the various text formatting features that are needed in the development of multimedia

Text: A single item of menu text accompanied by a single action requires little training and is clean and immediate. Use text for title and headlines, for navigation and for content, help to provide information about that particular thing. Computer screen provide a very small workspace for developing complex ideas. At some time or another, we will need to deliver high-impact or very concise text message on the computer screen in as condensed as possible. For designing perspective, our choice of font size and the number of headlines for place on a particular screen must be related both to the complexity of our message and to its venue. The text should be given according to situation like: if we are providing public-speaking sport, the text will be keyed to a live presentation where text accents the main message. In this case we use the large fonts and few word with a lot of space.

Animating Text:

There are plenty of way to retain a viewer's attention when displaying text. We can animate bulleted text and have it "fly" onto the screen. We can "group" a headline a character at a time. For speaker, simply highlighting the most important point works well as a pointing device. When there are several point to be made, we can stack keywords and flash them past the viewer in a timed automated sequence.

There are some powerful but inexpensive application are available like:- Xaos tools type Caster let us to create 3-D text using both true type and typel adobe fonts.

We can use illustrator and freehand EPS encapsulation post script outline file to create still images in 3-D and then animate the result to create quick time movie with broadcast quality rendering.

Using Text in Multimedia :

In multimedia the text is used for the title, headlines and for navigation and for contents.

Font and Faces For Text: A typeface is a family of graphic characters that usually includes many type sizes and style.

A font is a collection of character of a single size and style belonging to a particular typeface family, typically font style are the bold face and Italic face. Other style attribute, such as underlining and outlining of characters may be added by our computer software. Type size are usually expressed in points; .0138 inches or about of an inches. The font size doesn't exactly describe the height or width of its characters leading can be adjusted in most programs on both the Macintosh tool in window leading is providing appropriate line spacing. Leading is the spacing between character pair.

For example we can adjust the body width of each character from regular to condensed to expanded, in the Sabon font. Regular

  •  Condensed 
  •  Expanded.

Cases: These are basic all two cases for each word is available lowercase held the small letter. Today a capital letter is called uppercase, placing an uppercase letter in the middle of a word called an inter cap, is a trend that emerged from the computer programming communication.
Most Common font for window & Macintosh windows: Arial, book antiquam, bookman old style, bookshelf symbol, century gothic, comic sans MS, courier new, lucida console, marlett, MS sanssarig, MS serif, Times new roman,

Macintosh: Manaco, new york, palatino, symbol, times, chicago, geneva, helvetica, charcoal.

Making Pretty Text: To make our text pretty, we need a toolbox full of font and special graphics applications that can stretch, shade shadow, color, and anti-alias our words into real art Network pretty

text is typically found in bitmapped drawing where characters have been tweaked, manipulated with proper tools and a create mind, we can create. Endless variation on plain-old type and we not only choose but also customize the styles that fill with our design.

Hypermedia and Hypertext: Multimedia become interactive multimedia when we give the user some control over what information is viewed and when it is viewed. Interactive multimedia becomes hypermedia when its designers provide a structure of linked element through which a user can navigate and interact. When a hypermedia project includes large amount of text or symbolic content, this content can be indexed and its element than linked together to afford rapid electronic retrieval of the associated information. When word are keyed or indexed to other word, we have a hypertext system.

Images in Web Pages:

Most browsers will read only bitmapped JPEG and GIF image files. Vector files are a mathematical description of the lines, curves, fills and patterns needed to draw a picture, and while they typically do not provide the rich detail found in bitmaps, they are smaller and can be sealed without image degradation. Plugins to enable viewing vector formats are useful, particularly when some provide high-octane compression schemes to dramatically shrink file -size and shorten the time spent downloading and displaying them. File size and compression sound a recurring theme on the Internet, where data rich images, movies and sounds may take many seconds, minutes, or even longer to reach the end user. Vector graphics are also device independent-the image is always displayed at the correct size and with the maximum number of colors supported by the computer. Unlike bitmapped files, a single vector file can be downloaded, cached and then displayed multiple times at different scaled sizes on the same or a different web page.

Sound in Web Pages : Sound over the web is managed in a few different ways. Digitized sound files in various common formats such as. Way, AIV, or. Au may be sent  to our computer and then played, either as they are being received or once they are fully downloaded. MIDI files may also be received and played, these files are more compact. Speech files can be specially encoded into a token language and sent at great speed to another computer to be untokenized and played back in a choice of voices. Sounds may be embedded into projects made by Authorware, Quicktime, AVI and MPEG Movie files.
