  2. 2. Text and Fonts Text looks like the easiest medium to create and the least expensive to transmit, but there’s more to text creation than meets the eye! 2Multimedia Technologies (ITC-511) 03/17/12
  3. 3. Text Three types of text that are used to produce pages of documents:  Unformatted text: also known as plaintext and enables pages to be created which comprise strings of fixed-sized characters from a limited character set. 3Multimedia Technologies (ITC-511) 03/17/12
  4. 4. Text (Cont.)  Formatted text: also known as richtext and enables pages and complete documents to be created which comprise of strings of characters of different styles, size and shape with tables, graphics, and images inserted at appropriate points. 4Multimedia Technologies (ITC-511) 03/17/12
  5. 5. Text (Cont.) Hypertext: This enables an integrated set of documents (each comprising formatted text) to be created which have defined linkages between them. 5 Multimedia Technologies (ITC-511) 03/17/12
  6. 6. Fonts  Typeface A typeface is a family of graphic characters that usually includes many type sizes and styles e.g., Times, Courier and Helvetica are typefaces, each of which include many sizes & styles 6Multimedia Technologies (ITC-511) 03/17/12
  7. 7. Font  A font is a collection of characters of a single size and style, belong to a typeface family typical font styles are boldface, italic, bold italic, and underlined  font sizes are expressed in terms of points, where one point is .0138 or 1/72 inch,  where size is the distance from the top of capital letters to the bottom of descenders In lower-case letters such as g and j.  Times is a typeface; Times 12-point italic is a font In computers, however, people say “font” when “typeface” would be more accurate. 7Multimedia Technologies (ITC-511) 03/17/12
  8. 8. Leading  Leading (pronounced “ledding”) is the space between lines of text  Lopuck recommends increasing the leading to improve readability of text on a screen Character metrics  Character metrics are the measurements of individual characters  Vector-based fonts permit changes to character metrics for interesting effects; bit-based fonts do not 8Multimedia Technologies (ITC-511) 03/17/12
  9. 9. Kerning  Kerning is the spacing between character pairs Some fonts have variable kerning (e.g., Times), so have fixed kerning (e.g., Courier 9Multimedia Technologies (ITC-511) 03/17/12
  10. 10. Serif and Scans Serif  A serif font has little decorations at the end of each letter stroke  Times and Century are examples of serif fonts; Arial is a sans serif font  On printed pages, serif fonts are traditionally used for body text because they help guide the reader’s eye along the line of text  Headlines use sans serif text  Computer screens, with 72-dpi (dots per inch), don’t provide as much resolution as print, so it can be argued sans serif fonts are more legible in small sizes hence, 12-point Arial font (in Windows) is standard font 10Multimedia Technologies (ITC-511) 03/17/12
