Geared toward Perl users and webmasters, "Perl Graphics Programming focuses on open-source scripting programs that manipulate graphics files for use on the Web. The book demystifies the manipulation of graphics formats for newcomers to the Web with a practical, resource-like approach. With this book you'll learn to: generate dynamic Web graphics with charts, tables, and buttons; automate graphics tasks (thumbnails and borders); create dynamics Web documents (PDF, Postscript); and produce rich Internet experiences with Flash and SVG. You'll begin with a tour of the most common web graphic file formats--PNG, JPEG, GIF, SWF, SVG, Postscript and PDF then you'll explore the most powerful tools and Perl modules available for manipulating these graphics, such as GD, PerlMagick, and GIMP. Included in this part of the book is a thorough description of the Ming module for creating on-the-fly Flash files. Next, a "cookbook" section includes practical, all purpose recipes: GIF animation, generating images within a dynamic application, communicating between SWF front-end and Perl back-end, XSLT transformations, compression, and more.
Shawn Wallace has been applying computers to graphics problems for the past fifteen years. A programmer and artist, Shawn is managing director of the AS220 (www.as220.org) artist community in Providence, RI, a cofounder of the SMT Computing Society, and a member of the Rhode Island chapter of the Perl Mongers. He is also involved in the Bolero open source music notation system (www.as220.org/shawn/bolero) and the Institute for Folk Computing, a program to inform and inspire the use of open software by the general public in Providence. Shawn studied computer engineering at the University of Rhode Island and participated in the construction of an early (mid-80s) hypermedia delivery system at HyperView Systems in Middletown, RI.
