Abstract

From the Publisher:PNG (Portable Network Graphics) is the next-generationgraphics file format for the Web. Designed as an open-sourceformat to replace GIF (which uses a proprietary compressionscheme, for which software makers must pay a licensing fee),PNG is better, smaller, more extensible, and FREE. Already supported by major software like Macromedia Fireworks,Adobe Photoshop, and Microsoft Office 98, as well as NetscapeNavigator and Microsoft Internet Explorer, PNG is the next bigthing in computer graphics. Similar to the GIF and TIFF formats,but far better, PNG will soon become the preferred file format forcolor-critical web images and high-quality graphics interchange. Evenfor noncritical images, PNG will likely replace GIF as the standard webformat. PNG supports lossless compression, variable transparency information, and a range of color depths. PNG also provides direct support for gammacorrection, the cross-platform control of image "brightness," andtransparency. PNG: The Definitive Guide addresses the needs of graphicdesigners who want to get the most out of the format and programmerswho want to add full PNG-support to their own applications. Specifically,Roelofs covers implementing PNG with the libpng C library. The bookincludes explanations of important improvements with PNG, such asgamma correction and the standard color spaces for precise reproductionof image colors on a wide range of systems. PNG: The Definitive Guide is the first book devoted exclusivelyto teaching and documenting the important new format, PNG. It is an indispensable compendium for Web content developers and is chockfull of examples, sample code, and practical hands-on advice.
