Abstract: In this article the concept and characteristics of cross-platform are introduced. Based on the analysis of the structure of BMP images, several key points of cross-platform image processing programming are brought forward. Following these points, a number of cross-platform BMP image processing programs are written in the C++ language, and are built successfully under several platforms such as Linux/x86, FreeBSD, SunOS/sparc and Windows/x86-64. The experimental results show that cross-platform programming can boost the universality and compatibility of programs, broadening the way of programming techniques.

摘要： 本文介绍了跨平台的概念和特点，以及跨平台编程的思想，在对BMP图像结构分析的基础上，提出了编写跨平台图像处理程序的几个关键问题。并遵循这些要点，利用C++语言编写了若干跨平台BMP图像处理的程序，这些程序在Linux/x86, FreeBSD, SunOS/sparc, Windows/x86-64等多个平台下成功编译和运行。实验结果表明，跨平台编程可以大大提高程序的通用性和兼容性，为编程技术拓宽了思路。
