The first edition of this book was a traditional text book,
accompanied by a CD-ROM that contained all of the
information mentioned in the preceding section. In the second edition,
we've added to the book and completely retooled the
CD-ROM. Instead of finding a set of resource files
there, you'll find a software product that lets you browse the
complete text of the book (using Enhanced Mosaic, also provided) and
all of the specs, images, code examples, and software packages we've
been able to pull together, plus (with an Internet connection) a link
to the GFF Web Center.

Follow the installation instructions (see Appendix C) to get the
product up and running. From the Main Menu, you'll have the following choices:
- Formats. Information about all of the
formats we describe in Part Two of this book. From the format pages
you'll be able to link to vendor specification documents describing
the format, as well as to appropriate images and code examples and to
software packages that let you view, convert, and otherwise manipulate
the format. From Formats, you'll also be able to navigate to an Image
Lab offering a number of demos--for example, a color depth demo that
lets you display a particular image at a number of different depths
(from 2 to 8) and compare the results.
- Software. Freeware, shareware, or
commercial demo packages for a variety of platforms (Microsoft
Windows, MS-DOS, OS/2, the
Macintosh, and UNIX), as well as source code (for
such popular packages as pbmplus and xv, and for libraries of
TIFF, and other format functions).
- Internet. We're committed to keeping
this product up to date. If you have an Internet connection, you can
link to the GFF Home Page to see what's new at the
GFF Web Center. There you'll find updates to the
product (new file formats, code, and images), additional information
about computer graphics and file formats (e.g., Frequently Asked
Questions listings [FAQs], graphics news), and
links to updated versions of the specs and software included on our
- The Book. The complete online text of
Parts One and Three of the book, with cross-references and links that
will help you navigate more easily through the text.
- Index. A complete index to the contents of the product.
We could say a lot more about what's available and how it all works,
but the best way to find out is to jump in and try it for yourself.
