摘　　要：通过研究行程编码的信息存储方式,对行程编码进行了改进,并针对未改进和改进后行程编码各自的不足,提出了将两者综合运用的方法.同时根据图像的局部性原理,研究了在行程编码的基础上进行有损压缩和优化压缩路径,从而进一步提高了位图的压缩效率.By studying information storage measures for RLE（Run Length Encoding）, the article introduces how to improve RLE.Because both RLE and improved RLE have disadvantages, the application of RLE combined with improved RLE is presented. And according to the local principle of image, the article discusses a lossy compression based on RLE and optimization of path of Compression that contribute to the raise of ratio in bitmap compression.
