Description: 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。-First, use the TCP protocol to transmit data. Reason: better stability.
Two, the use of byte data stream for transmission, the reasons:
A: VB s String existence automatic Unicode conversion question, effects of speed
B: can directly send 8-bit byte data, Does not need to use Base64 encoding, thereby reducing the encoding time.
Three, the use of GIF-LZW compression algorithm for image compression. Rationale:
A: Run-Length Coding, Huffman compression algorithm compression ratio is too low
B: JPEG compression algorithm required too many bit computing, and computing a large quantity (MMX has specialized optimization algorithm), VB is not conducive to implementation
C: GIF-LZW compression algorithm compression ratio is better, and I have come up with efficient under VB grammar GIF-LZW compression/decompression algorithm.
Four, use the "orderly jitter" algorithm for color quantization. Rationale: "orderly jitter" must deal with the results of reg
