Publisher's Note
This comprehensive reference on the major graphics file formats and the compression technologies they employ is an indispensable resource for graphics programmers, especially those developing graphical applications for the Web. Compressed Image File Formats: JPEG, PNG, GIF, XBM, BMP examines the most common graphics file formats in detail and demonstrates how to encode and decode image files for each. In particular, this book offers in-depth coverage of the elaborate JPEG and newer PNG formats, providing clear explanations of complex concepts, experience-based practical techniques, and plentiful code examples. GIF, XBM, and BMP are also covered, with a focus on some of the less familiar and less well-documented features of these common file formats. Specific topics covered include: - Compression technologies that each file format utilizes
- Color models employed by each file format
- The advantages and disadvantages of each file format
- Huffman Coding
- LZW Compression
- Deflate/Inflate
- Progressive JPEG
- The Discrete Cosine Transform
- Animated GIF
The accompanying CD-ROM contains the complete source code for all of the image formats covered in the book, as well as working examples and sample images. If you want to learn how to read and write graphic file formats for the Web--including PNG and JPEG files--there is no better resource than this book. System requirements: Windows 95 or Windows NT, Borland C++ Builder 3, or Microsoft Visual C++ 5.0.

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
