Available in PDF, EPUB and Kindle. Book excerpt: 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. It is a little documented field, however, and the many valuable free libraries and tools available on the Internet remain under-utilized. Programming Web Graphics with Perl and GNU Software is aimed at intermediate and advanced Web users who want to use CGI scripts to generate dynamic graphic content. It will also help to demystify the manipulation of graphics formats for newcomers to the Web. Programming Web Graphics with Perl and GNU Software takes a practical, resource-like approach to the content. It is not a book about design or aesthetics of Web graphics; its focus is on programming or, more accurately, scripting programs that manipulate graphics file to be published on the Web. Most of the examples in the book use Perl as a scripting language, though the concepts are applicable to any programming language. However, several powerful Perl modules for generating graphics (GD, PerlMagick, GIFgraph) should help position Perl as a major contender for your Web graphics applications. Most of the topics covered in the book are applicable to any platform (NT, Linux, Un*x, MaxOS), with the exception of the chapter detailing the Gnu Image Manipulation Program (a free Adobe Photoshop-like application), which requires a connection to an X server. The focus is always on free software, when it is available. This 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 extensive documentation and examples using the Perl graphics modules GD and GIFgraph, and the Perl interface to the 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 new 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 cams the creation of animated GIFs on-the-fly One of the key ingredients to the success of the Web is that anyone who wanted to could participate in publishing to the wo ...

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Programming on the Web today can involve any of several technologies, but the Common Gateway Interface (CGI) has held its ground as the most mature method--and one of the most powerful ones--of providing dynamic web content. CGI is a generic interface for calling external programs to crunch numbers, query databases, generate customized graphics, or perform any other server-side task. There was a time when CGI was the only game in town for server-side programming; today, although we have ASP, PHP, Java servlets, and ColdFusion (among others), CGI continues to be the most ubiquitous server-side technology on the Web.CGI programs can be written in any programming language, but Perl is by far the most popular language for CGI. Initially developed over a decade ago for text processing, Perl has evolved into a powerful object-oriented language, while retaining its simplicity of use. CGI programmers appreciate Perl's text manipulation features and its CGI.pm module, which gives a well-integrated object-oriented interface to practically all CGI-related tasks. While other languages might be more elegant or more efficient, Perl is still considered the primary language for CGI.CGI Programming with Perl, Second Edition, offers a comprehensive explanation of using CGI to serve dynamic web content. Based on the best-selling CGI Programming on the World Wide Web, this edition has been completely rewritten to demonstrate current techniques available with the CGI.pm module and the latest versions of Perl. The book starts at the beginning, by explaining how CGI works, and then moves swiftly into the subtle details of developing CGI programs.Topics include: Incorporating JavaScript for form validation Controlling browser caching Making CGI scripts secure in Perl Working with databases Creating simple search engines Maintaining state between multiple sessions Generating graphics dynamically Improving performance of your CGI scripts

Available in PDF, EPUB and Kindle. Book excerpt: Get an In-Depth Understanding of Graph Drawing Techniques, Algorithms, Software, and Applications The Handbook of Graph Drawing and Visualization provides a broad, up-to-date survey of the field of graph drawing. It covers topological and geometric foundations, algorithms, software systems, and visualization applications in business, education, science, and engineering. Each chapter is self-contained and includes extensive references. The first several chapters of the book deal with fundamental topological and geometric concepts and techniques used in graph drawing, such as planarity testing and embedding, crossings and planarization, symmetric drawings, and proximity drawings. The following chapters present a large collection of algorithms for constructing drawings of graphs, including tree, planar straight-line, planar orthogonal and polyline, spine and radial, circular, rectangular, hierarchical, and three-dimensional drawings as well as labeling algorithms, simultaneous embeddings, and force-directed methods. The book then introduces the GraphML language for representing graphs and their drawings and describes three software systems for constructing drawings of graphs: OGDF, GDToolkit, and PIGALE. The final chapters illustrate the use of graph drawing methods in visualization applications for biological networks, computer security, data analytics, education, computer networks, and social networks. Edited by a pioneer in graph drawing and with contributions from leaders in the graph drawing research community, this handbook shows how graph drawing and visualization can be applied in the physical, life, and social sciences. Whether you are a mathematics researcher, IT practitioner, or software developer, the book will help you understand graph drawing methods and graph visualization systems, use graph drawing techniques in your research, and incorporate graph drawing solutions in your products.
