44291-3 Leverage the power of XIE image processing in your X Windows applications! The XIE extension to X Windows enables developers to quickly create robust, highly-efficient image display and enhancement software. Developing Imaging Applications with XIElib is the first book to deliver practical answers, hands-on guidance, strategies and XIElib sample code for solving real image processing problems. The book starts with an overview of image processing for developers new to the field. Next, it introduces XIElib and the problems it is intended to solve. The book covers all critical aspects of XIElib development, including: *Working with photoflos and resources *New high-level routines that simplify I/O *Importing and exporting images in multiple graphics formats *Managing process elements *XIElib event and error handling *Making sure that image data is compatible with the colormap and visual of a window You'll find never-before-published guidance on essential XIElib techniques such as dithering, colorspaces, geometry, and image encoding and decoding-with especially detailed coverage of JPEG.Several complete sample clients are provided in the book and on CD-ROM, both to illustrate XIElib client writing and provide a starting point for your own applications. XIE represents a breakthrough in image processing, but practical developer's information about it has been scarce-until now. Developing Imaging Applications with XIElib gives you the information, tools and sample code you need to create XIElib visual applications more powerful than you ever imagined.
