1. Importance of Text  in a Multimedia Presentation -Text  is  obviously  the  simplest  of data  types  and  requires  the  least amount  of  storage. -Text in the form of symbols, words, sentences, and paragraphs. -Text is a vital element of multimedia menus, navigation systems, and content.

2. Understanding Fonts and Typefaces  -A typeface is a family of graphic characters, often with many type sizes and styles. -A font is a collection of characters of a single size and style belonging to a particular typeface family. -The study of fonts and typefaces includes the following:       1)Font styles       2)Font terminology       3)Cases -Serif versus sans serif

2.1. 1)Font styles      -Boldface      -Italic      -Underlining      -Outlining 2)Font terminology      -Baseline      -Cap height        -x-height        -Ascenders/descenders      -Kerning       -Tracking 3)Cases       -A capitalized letter is referred to as uppercase, while a small letter is referred to as lowercase.

2.2. Serif   -A serif is the little decoration at the end of a letter stroke. San Serif   -Sans serif fonts do not have decoration at the end of a letter stroke.

3. Using Text Elements  in a Multimedia Presentation -The text elements used in multimedia are: -Menus for navigation -Interactive buttons -Symbols and icons -Fields for reading -HTML documents -Some of the commonly used tags are: -Choosing text fonts

4. Computers and Text -Bitmap font and Vector font -Character sets -Extended Character Set (ISO Latin-1) -Unicode

5. Bitmap vs Vector -Fonts can either be stored as bitmapped or vector -Bitmaps font consist of a matrix of dots or pixels representing the image. -Vector fonts drawing use instructions and mathematical formulae to describe each glyph. -Can draw any size by scaling the vector drawing primitives mathematically

6. Rasterization  -Font rasterization is the process of converting text from a vector description to a raster or bitmap description -Jaggies are the jagged edges you see when a bitmapped image is resized

7. Anti-aliasing -Antialiasing blend the font into the background color. It refers to the smoothing of jagged edges of drawn graphics and text to improve their appearance or readability

8. Font Mapping -Specifying which font to be substitution is called font mapping.

9. Font Editing and Design Tools -FontLab, Ltd. -Creating attractive texts -Fontographer

10. Hypertext vs Hypermedia 1)Hypertext 2)Hypermedia -A hypertext or hypermedia system enables the user to navigate through text in a nonlinear way.

10.1. 1)Hypertext      -Hypertext is a text which contains links to other texts. 2)Hypermedia     -Hypermedia is not constrained to be text-based.

11. Hypermedia Structure -Navigating hypermedia structures - Hypermedia structures -Links -Nodes -Anchors -Hypertext systems are used for:
