作为数字图像处理技术的实现环节，本书将在Visual C++环境下介绍图像各种典型算法的编程实现。而作为一本书的开始，本章我们将介绍图像编程的基础知识，如数字图像的点阵数据、调色板概念、BMP文件结构以及设备无关位图（DIB）等，它是后面章节学习的基础。-As a digital image processing technology to achieve aspects of the book image of typical programming algorithm is introduced Visual C++ environment. As the beginning of a book, this chapter we will introduce the basics of graphics programming, such as the lattice data of the digital image, the palette concept, BMP file structure and device-independent bitmap (DIB), it is the later chapters to learn foundation.
