Compressed Image File Formats

Since not all graphic formats are of equal complexity, author John Miano does not simply choose a number of file formats and devote a chapter to each one. Instead, he offers additional coverage for the more complex image file formats like PNG (a new standard) and JPEG, while providing all information necessary to use the simpler file formats. While including the well-documented BMP, XBM, and GIF formats for completeness, along with some of their less-covered features, this book gives the most space to the more intricate PNG and JPEG, from basic concepts to creating and reading actual files. Among its highlights, this book covers: -- JPEG Huffman coding, including decoding sequential mode JPEG images and creating sequential JPEG files-- Optimizing the DCT-- Portable Network Graphics format (PNG), including decompressing PNG image data and creating PNG files-- Windows BMP, XBM, and GIF

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.

Computing Methodologies -- Computer Graphics.

Fuses design fundamentals and software training into one cohesive book! The only book to teach Bauhaus design principles alongside basic digital tools of Adobe's Creative Suite, including the recently released Adobe CS4 Addresses the growing trend of compressing design fundamentals and design software into the same course in universities and design trade schools. Lessons are timed to be used in 50-minute class sessions. Digital Foundations uses formal exercises of the Bauhaus to teach the Adobe Creative Suite. All students of digital design and production—whether learning in a classroom or on their own—need to understand the basic principles of design in order to implement them using current software. Far too often design is left out of books that teach software. Consequently, the design software training exercise is often a lost opportunity for visual learning. Digital Foundations reinvigorates software training by integrating Bauhaus design exercises into tutorials fusing design fundamentals and core Adobe Creative Suite methodologies. The result is a cohesive learning experience. Design topics and principles include: Composition; Symmetry and Asymmetry; Gestalt; Appropriation; The Bauhaus Basic Course Approach; Color Theory; The Grid; Scale, Hierarchy and Collage; Tonal Range; Elements of Motion. Digital Foundations is an AIGA Design Press book, published under Peachpit's New Riders imprint in partnership with AIGA, the professional association for design.

by CDs, but we continue to utilize the same general format of morning didactics and afternoon glass slide review and small group interactions. One of our biggest successes was in the ever-expanding set of didactic lecture notes and radiologic, gross, microscopic, ultrastructural, and other images that course participants received, so it wasn’t much of a surprise when we were approached by the publisher to consider creating an updated compilation of some of the best talks and packaging them in a monograph available to a broader population of physicians and scientists. With the extraordinary attention to detail that he is known for, my co-editor David Chhieng has been both the brains and the brawn of this project, resulting in the bringing together of such a collection while trying to be sensitive and representative of the various branches of pathology reflected in the actual course. From surgical pathology, chapters cover select topics in endocrine, gynecologic, GU, and GI pathology with contributions from Walter Bell, Michael Conner, Katrin Klemm, and Audrey Lazenby, respectively. Tom Winokur has begun to prepare us for the near future with a treatise on molecular markers in breast cancer. The interactive nature of cytopathology and surgical pathology are brought together by Claudia Castro [now at the U. T. Medical Branch at Galveston] and David Chhieng in three chapters covering mediastinal, pleural, and pulmonary pathology.

Created by the Joint Photographic Experts Group (JPEG), the JPEG standard is the first color still image data compression international standard. This new guide to JPEG and its technologies offers detailed information on the new JPEG signaling conventions and the structure of JPEG compressed data.

Now adapted for Mac OS X, this bestseller shows photographers how to make their images pop with Photoshop Elements 8--Best-selling guide is fully updated to include all the new features in Photoshop Elements 8 for Mac OS X.-Loaded with tips and techniques this book covers all the new features including-Auto-analyzer, People Recognition, one-step color and lighting adjustments, and more.-Step-by-step instructions, accessible style, and low price point make this an ideal guide to Elements 8. Photoshop Elements is geared for business users, students, educators, and home users who want professional-looking images for their print and Web projects, but don't want or need the advanced power of Adobe Photoshop. With Photoshop Elements 8 for Mac OS X: Visual QuickStart Guide, readers can start with a tour of the interface and image-editing basics, or they can look up specific tasks to learn just what they need to know. This task-based, visual reference guide uses step-by-step instructions and plenty of screenshots to show readers how to capture and import photos, reduce red eye, enhance color, work with layers, and much more. Coverage includes: applying direct effects with the Adobe Smart Brush, softening surfaces and keeping edges crisp with a new filter, finding photos easily with keywords, and complete coverage of the new features including People Recognition, Auto-Analyzer, any-size photo recomposition, one-step color and lighting adjustments, multiple computer photo library synchronization, and more. Both beginning and intermediate users will find everything they need here--in straightforward language and with readily accessible examples.

From a senior researcher who helped design the PNG image format comes a guide that focuses on implementing PNG with the libpng C library and discusses improvements, such as gamma correction and the standard color spaces for precise reproduction of image colors on a wide range of systems.
