This volume focuses onillegalscripting programs that enable programmers to manipulate graphics for the Web. While most of the examples use Perl as aillegalscripting language, the concepts are applicable to any programming language.
Graphics programmers aren't the only ones who need to be proficient with graphics. Web and applications programmers know that a dull web page can be quickly transformed into one that's interesting and lively with the use of well-planned graphics. And fortunately, you don't need the skills of a fulltime graphics programmer to use graphics effectively. From access counters and log report graphs to scientific plots and on-the-fly animated GIFs, graphicsillegalscripting is within the grasp of most web programmers. Using open source software, like Perl, you have the power to dynamically generate graphics based on user input and activity, easily manipulate graphics content, and optimize graphics for compression and quality.nnGeared toward Perl users and webmasters, Perl Graphics Programming focuses on open-sourceillegalscripting 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 umbnails and borders) - Create dynamics web documents (PDF, Postillegalscript) - Produce rich Internet experiences with Flash and SVG.nYou'll begin with a tour of the most common web graphic file formats--PNG, JPEG, GIF, SWF, SVG, Postillegalscript 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 deillegalscription 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 much more.nnPerl programmers naturally turn to Perl to tackle whatever challenge they have at hand, and graphics programming is no exception. Perl Graphics Programming provides all the tools you need to begin programming and designing graphics for the Web immediately. This book will change how you think about generating and manipulating graphics for the Web.
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.
