More copies of this ISBN:Other titles in the SIGGRAPH Series series:Compressed Image File Formats: JPEG, PNG, GIF, Xbm, BMP with CDROM (SIGGRAPH Series)by John Miano
Synopses & ReviewsPublisher Comments: 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:
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. 0201604434B04062001 Book News Annotation:Shows graphics programmers how to write software that can read and
write files using various 2-D image formats associated with Web
browsers. Topics include compression technologies, color models,
Huffman code generation, block ordering, the discrete cosine
transform, and animated GIF. The CD-ROM contains source code and
examples in C++.
