| Flash, a popular authoring software developed
by Macromedia, Flash is used to create
vector graphics-based animation programs with full-screen
navigation interfaces, graphic illustrations, and simple
interactivity in an antialiased, resizable file format that is
small enough to stream across a normal modem connection. The
Flash software is ubiquitous on the Web, both
because of its speed (vector-based animations, which can adapt
to different display sizes and resolutions, play as they
download) and for the smooth way it renders graphics.
Flash files, unlike animated but rasterized
GIF and
JPEG, are compact, efficient, and designed for optimized
delivery.
Known as a do-it-yourself animation package,
Flash 4 gives Web designers the ability to
import artwork using whatever bitmap or illustration tool they
prefer, and to create animation and special effects, and add
sound and interactivity. The content is then saved as file with
a .SWF file name extension.
Web users with Intel Pentium or Power Macintosh processors
can download Flash Player to view
Flash content, which performs across multiple
browsers and platforms. Flash is lauded for
being one of the Web's most accessible
plug-in. According to an independent study cited by
Macromedia, 89.9 percent of Web users already have Flash Player
installed.
