Synopsis

From access counters and log-report graphs to scientific plots and on-the-fly animated GIFs, graphics scripting is within the grasp of most Web authors. This text is aimed at intermediate and advanced Web users who want to use CGI scripts to generate dynamic graphic content. It also aims to help demystify the manipulation of graphics formats for newcomers to the Web. The book covers the following: a tour through the most popular Web graphics file formats by implementing parsers for GIF, JPEG, and PNG files; descriptions of the PNG, JPEG and giflib libraries, as well as many other free and proprietary libraries and SDKs; documentation and examples using the Perl graphics modules GD and GIFgraph, and the Perl interface; powerful ImageMagick libraries; documentation on the GNU Image Manipulation Program (GIMP) and the Perl interface that lets you easily script plug-ins or interface to the GIMP via the Web; the creation of image maps from data extracted from a database; the implementation of several Perl modules for the creation of neatly formatted PostScript files; details on interfacing to a fax gateway; reusable recipes for many popular applications such as Web counters and Web cam; the creation of animated GIFs on-the-fly; and optimizing graphics generation on the server-side.

Media Reviews
'...is a cross between a how to manual and an idea book. It will empower readers in the often mystical area of graphic creation and suggest new ways to give web sites lively, dynamic content, all without spending a penny on software. 454 pages are hardly enough to provide a thorough course in every tool mentioned, but in each case there is enough material to lift the reader to basic confidence, and the references to take them further. Although without some knowledge of Perl it might be intimidating, the text should be accessible to the complete graphics novice. Shawn Wallace has written an excellent book on a topic which deserves it. '--Gavin Inglis, news@UK, June 2000
