Description: （利用GIF_LZW算法实现的）网络图片传输 技术特点 ~~~~~~~~ 一、使用TCP协议传输数据。理由：稳定性好。 二、使用字节数据流进行传输，理由： A:VB的String存在自动Unicode转换问题，影响速度； B:可以直接发送8位字节数据，不需要使用Base64编码，从而减少了编码时间。 三、使用GIF-LZW压缩算法压缩图像。理由： A:行程编码、Huffman压缩算法压缩率太低； B:JPEG压缩算法需要太多位运算，且运算量大（有专门MMX优化算法），不利于VB实现； C:GIF-LZW压缩算法压缩率较好，且我已想出VB语法下高效GIF-LZW压缩/解压算法。 四、使用“有序抖动”算法进行 色彩量化。理由：“有序抖动”处理的结果具有一定规律性，有助于LZW类算法压缩。-(using GIF_LZW algorithm) picture transmission network ~~~~~~~~ a technical features, the use of TCP to transmit data. Reason : good stability. Two, the use of byte data stream for transmission, reasons : A : VB String exist automatically Unicode conversion, the impact speed; B : can directly send eight bytes of data and do not need to use Base64 encoding, thereby reducing the coding time. 3, the use of GIF- LZW compression algorithm for image compression. Reason : A : itinerary coding, Huffman compression algorithm compression rate is too low; B : JPEG compression algorithm needs much-bit computing, and large amount of computation (with MMX specialized optimization algorithm), is not conducive to VB; C : GIF- LZW compression algorithm compression ratio better, and I have come up with un Platform: |
