1.3. Vital element of multimedia menus, navigation systems, and content.

2. Typeface & fonts

2.1. typeface

2.1.1. family of graphic characters, often with many type sizes and styles.

2.1.2. Example : Bookman Old Style

2.2. Fonts

2.2.1. collection of characters of a single size and style belonging to a particular typeface family.

2.2.2. Example : Arial 18 point Bold

2.3. fonts and typefaces includes

2.3.1. Font styles

2.3.1.1. Boldface/Italic/Underlining/Outlining

2.3.2. Font terminology

2.3.2.1. Baseline – the line on which the bases of characters are arranged

2.3.2.2. Cap height - cap height refers to the height of a capital letter

2.3.2.3. x-height – the distance between the baseline and the top of a lower-case letter x

2.3.2.4. Ascenders/descenders – strokes that rise above the x-height/drop below the baseline

2.3.2.5. Kerning – adjustment of space between certain pairs of letters (e.g. AV) to make them look more uniform

2.3.2.6. Tracking - adjustment of space for groups of letters

2.3.2.7. Serif versus sans serif

3.1. Menus for navigation

3.1.1. A user navigates through content using a menu

3.1.2. A simple menu consists of a text list of topics.

3.2. Interactive buttons

3.2.1. A button is a clickable object that executes a command when activated

3.3. Fields for reading

3.3.1. Reading a hard copy is easier and faster than reading from the computer screen.

4. Bitmap vs Vector

4.1. Bitmaps Font

4.1.1. consist of a matrix of dots or pixels representing the image

4.1.2. File size increases as more sizes are added

4.1.3. Require a lot of memory

4.1.4. Non-scalable

4.2. Vector fonts

4.2.1. drawing use instructions and mathematical formulae to describe each glyph

4.2.2. File size is much smaller than bitmaps

5. Rasterization

5.1. The process of converting text from a vector description to a raster or bitmap description

5.2. The jagged edges you see when a bitmapped image is resized

6. Anti-aliasing

6.1. Antialiasing blend the font into the background color

7. Computers and Text

7.1. Character sets

7.1.1. Each character is represented by a unique 7-bit binary code word, meaning that there are 128 (27) alternative characters

7.2. Extended Character Set (ISO Latin-1)

7.2.1. Extra 1 bit in ASCII –up to 256 characters is used while

7.2.2. EXAMPLE:¢ ä ü

9. Font Editing and Design Tool

9.1. Fontographer is a specialized graphics editor

9.2. It can also modify existing typefaces and incorporate PostScript artwork

10. Hypertext vs Hypermedia

10.1. Hypertext: text which contains links to other texts

10.2. Hypermedia: not constrained to be text-based

10.2.1. Navigating hypermedia structures

10.2.1.1. The simplest way to navigate hypermedia structures is via buttons

10.2.2. Hypermedia structures

10.2.2.1. Links

10.2.2.1.1. connections between conceptual elements.

10.2.2.2. Nodes

10.2.2.2.1. accessible topics, documents, messages, and content elements.
