內容描述

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.
