| 中文摘要 | 根据无线通信领域特别是手机通信领域图像传输与显示的特点,对PNG(portable network graphic format),GIF(graphics interchange format),WBMP(wireless bitmap)J,PEG(joint photographic experts group)等图像格式的优缺点进行了比较。详细分析了PNG图像的格式和压缩编码过程,针对PNG图像格式的编码过程的各个环节进行了优化处理,编制了PNG图像压缩编码优化软件。通过和OptiPng,Pngout,Pngrewrite,AdvPng等优化工具进行优化测试对比,充分体现出压缩比例高,适用图片种类广泛的特点。; According to the image transferring and displaying characteristics in wireless communication area,especially in cellular phone communication area,the PNG file format and its encoding process is analyzed and a scheme of optimization to the encoding process of PNG image type is proposed.Through the optimization performance comparison with OptiPng,Pngout,Pngrewrite and AdvPng,the optimization shows its features as high compression rate and high applicability. |
