Text in MM Applications
• Be concise.
– Infomap.com
• Fonts: serif, sans serif,
decorative
• See page 27
• In dealing with font
design, use constraint
and be consistent
Using Text on the Web
• Browsers: IE,
Netscape, Opera
• Fontset
• CSS
• Image Maps
• Special
circumstances
Using Graphics in MM Applications
• Two main types of graphics are used
MM: draw-type (vector based) and
bitmap
– Draw-type advantages: ability to resize and
rotate; smaller file size;
– Draw-type disadvantages: more complex
take longer to load; not photo quality
Using Graphics in MM Applications
• Continued
– Bitmap graphic advantages: excellent
photographic ability lies within the subtle
color gradient abilities; quality is generally
higher than draw-type
– Bitmap graphic disadvantage: much larger
file which can easily take up too much
room within storage.:
