Résumé
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, graphics
scripting 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.
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)
- 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 much more.
Perl 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.
