  By John Miano Addison-Wesley Professional Paperback (288 pages) Amazon.com: Compressed Image File Formats is an appealingly compact and useful guide to some of today's most popular file formats used for image data. For any programmer who needs to know how images are stored, this concise reference can serve as a really invaluable resource. Besides full coverage of the popular BMP, GIF, and PNG file formats, the book zeroes in on the JPEG standard, perhaps today's most popular (and most complicated) image format. In a series of short chapters, the book looks at JPEG in detail, from basic file organization (its format and marker fields), file compression techniques (like Huffman coding and DCT), and how to decode (read) and encode (write) JPEG images. By condensing hundreds of pages of specifications and documentation from the voluminous JPEG standard into this short volume, the author has created a worthwhile summary of key JPEG features and compression techniques useful to any graphics programmer. The book also includes C++ code for a simple JPEG encoder (on the accompanying CD-ROM). This example can get you started compressing images using the JPEG format. In addition, the book discusses techniques for creating and decoding progressive JPEGs (used for downloading images in stages, in progressively finer resolutions, over the Internet). Whether you are a programmer faced with decoding or encoding image data, or an interested Webmaster who wants to know the pros and cons of today's image file formats, Compressed Image File Formats provides a worthwhile and concise reference to what's inside image files. --Richard Dragan Topics covered: bitmap basics, color models, Windows BMP file format, XBM file format, JPEG basics and file format, JPEG File Interchange Format (JFIF), JPEG Huffman Coding, data unit encoding, Discrete Cosine Transform (DCT), matrix operations, JPEG decoding and encoding, progressive JPEG, GIF file format and compression, and PNG file format.
