Computing Methodologies -- Computer Graphics.

Over 100 entries on file formats written to aid in the retrieval of graphics data regardless of the state of industry documentation of format specifications. Includes an overview of graphics data retrieval, treating subjects such as bitmap and vector files, platform dependencies, format conversion, and data compression. The CD-ROM includes the entire contents of the book, a world wide web browser, sample code that reads and writes a variety of formats, and third party utilities for file manipulation and conversion.

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

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.
