Text as a component of multimedia

1. Text

2. Introduction Text is one of the most imperative components of multimedia and an essential source of presenting information to a wide range of people. Proper use of text, keeping in mind elements such as font style, size and various design tools help the content creator to communicate the idea and message to the user. Text is also the most widely used and flexible means of communicating information and ideas on an electronic media.

3. Fonts and Faces Factors affecting legibility of text are as follows : Size and style Background and foreground colours Leading Selecting Text Fonts Choose a font that is legible and easy to read . The different effects and colours of a font can be chosen to make the text look distinctive. Try to use few different colours within the same presentation. Try to use few typefaces within the same presentation. Play with the style and size to match up to the purpose and importance of the text. For instance, use large font size for headings . Drop caps and initial caps can be used to accent the words. Anti-aliased can be used to make a text look gentle and blended.

4. Using Text in Multimedia From design point of view, text should fill less than half the screen. There are following ways in which a text can be used in multimedia : in text messaging in advertisements in a website in films such as titles and credits as subtitles In a film or documentary that provide a translation Using Text Elements in a Multimedia Presentation Menus for Navigation Interactive Buttons Fields for Reading HTML Documents Symbols and Icons Text in Films such as Titles

5. Font Editing and Design Tools A font editor is a class of application software specifically designed to create or modify font files . Font editors differ greatly depending on if they are designed to edit bitmap fonts or outline fonts . Most modern font editors deal with the outline fonts. Special font editing tools can be used to make your own type, so you can communicate an idea or graphic feeling exactly. With these tools , professional typographers create distinct text and displays faces . ResEdit ResEdit is a source editor available from apple that is useful for creating and changing graphic resource such as cursors, icons, dialog boxes, patterns, keyboard maps, and bitmapped fonts on the Macintosh. It can be used to edit or create new font resources for storing the bitmaps of screen fonts . Fontographer Fontographer is a powerful font editor supplied by Macromedia, is a specialized graphics editor for both Macintosh and Windows platforms. You can use it to develop PostScript, TrueType and bitmapped fonts for Macintosh, Windows,DOS , NeXT, and Sun workstations. Designers can also modify existing typefaces, incorporate PostScript artwork, automatically trace scanned images, and create designs from scratch. Fontographer’s features include a freehand drawing tool to create professional and precise in-line and outline drawings of calligraphic and script characters.

6. Type-Designer Type-Designer for windows from DS Design is a font editor that lets you create, convert,and manipulate PostScript Type1 and TrueType fonts as well as EPS file format illustrations. An extensive palette of editing tools allows you to make changes to a font’s outline. With Type-Designer you can open up to eight typefaces simultaneously and cut and paste characters between them . Font Monger Font Monger from Ares Software offers a proprietary hinting technology to ensure that your fonts will look good regardless of size. To create new fonts or to manipulate existing ones, Font Monger includes a freehand drawing tool, a scissors tool, and a gizmo tool that rotates, slants, and skews character outlines .

7. Cool 3D Text Cool 3D Production Studio is a program for creating and animating 3D text and graphics, for videos and other multimedia products. This software runs on Windows 98SE/ ME/2000/ XP.With this program, a user can create 3D graphics, animations for videos. It includes new modelling tools , animations plugs-in, and new features for animation and video.

8. Font Chameleon Font Chameleon from Ares software for both Macintosh and Windows platforms builds millions of different fonts from a single master font outline. The program provides a number of pre-set font descriptors, which you build into a PostScript Type 1, or True Type Font . With slide bars you can manipulate various aspects of the font, including its weight,width , x-height, ascenders and descenders , and the blend of the serifs.

9. Making Pretty Text To make your text look pretty, you need a toolbox of fonts and special graphics applications that can stretch, shade, shadow, colour , and anti-alias your words into real artwork. Most designers find it easier to make pretty type starting with ready-made fonts, but some will create their own custom fonts using font-editing and design tools such as Fontographer,Type -designer , and Font Monger.

10. Hypermedia and Hypertext Hypermedia information spaces are connected by non-linear links which a user may follow in any order. Multimedia information spaces are arranged sequentially, with only one path through the information provided . Hypertext is different from normal text in that it is nonlinear. The reader need not read a document from beginning to end, but can jump around within the document by clicking on hot spots (or hyperlinks) in the text . On the other hand, hypermedia involves more than simply hyperlinked text. It also incorporates images , sounds, and video into the document. This allows for a more graphical interface to information . Most web pages should be considered hypermedia instead of simply hypertext

11. Using Hypertext Systems Information management and hypertext programs present electronic text, images, and other elements in a database fashion. Software robots visit Web pages and index entire Web sites. Hypertext databases make use of proprietary indexing systems. Server-based hypertext and database engines are widely available.

12. Hypermedia Structures Links Nodes Anchors Navigating hypermedia structures Nodes Nodes are accessible topics, documents, messages and content elements. Nodes and links form the backbone of a knowledge access system

13. Anchors Anchor is defined as the reference from one document to another document, image, sound,or file on the Web. The destination node linked to the anchor is referred to as a link end. The source node linked to the anchor is referred to as a link anchor . Navigating Hypermedia Structures Location markers must be provided to make navigation user-friendly. The simplest way to navigate hypermedia structures is via buttons
