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

Description: GIF87a的压缩，解压缩及一些工具的源代码，稍微修改就可以支持GIF89a，
可以在vc中使用，解码的话只需要一个文件DGIF_LIB.C（头文件还是需要的）,加入工程中就可以使用，显示实例可以参考文件gif2herc.c中的main函数-GIF87a compression, decompression tools and the source code, it can be slightly modified to support GIF89a, the vc used, decoding the only one document DGIF_LIB.C (header files or need), join the project can use it, showing examples can reference document gif2herc.c the main function

Description: 把Picture中的图片保存为Gif格式
把bmp文件保存为gif文件，没有使用任何Dll，完全使用VB实现。在压缩比上还有所欠缺，算法有待改进。-put the photographs to preserve Gif formats bmp file documents to gif, Dll not use any fully use VB. The compression ratio, which had been lacking, the algorithm needs improvement.

Description: GIF(Graphics Interchange Format，图形交换格式)文件是由 CompuServe公司开发的图形文件格式，版权所有，任何商业目的使用均须 CompuServe公司授权。
GIF图象是基于颜色列表的（存储的数据是该点的颜色对应于颜色列表的索引值），最多只支持8位（256色）。GIF文件内部分成许多存储块， 用来存储多幅图象或者是决定图象表现行为的控制块， 用以实现动画和交互式应用。GIF文件还通过LZW压缩算法压缩图象数据来减少图象尺寸-GIF (Graphics Interchange Format, Graphics Interchange Format) file developed by CompuServe graphics file format, all rights reserved, any commercial purposes CompuServe shall be authorized to use. GIF image is based on the color list (stored data is the point of the color corresponds to the color index value list), only supports up to 8-bit (256 colors). GIF files are divided into a number of internal storage block, used to store multiple images or images that determines the performance behavior of control block for the realization of animation and interactive applications. GIF files also LZW compressed image data compression algorithm to reduce the image size

Description: 可以方便的制作手机壁纸:
1.支持bmp,jpg,gif(gif只支持第一帧),png格式
2.输出格式为jpg,因为我感觉小尺寸的图片文件在图片失真不严重的情况下jpg格式比其他格式友更好的压缩比
3.支持图片翻转,平滑等特效
4.操作简单,方便易用.-You can easily create mobile phone wallpaper: 1. Supports bmp, jpg, gif (gif only supports the first frame), png formats 2. Output format jpg, because I felt that the small size of the picture files in the image distortion is not severe cases, jpg format, a better friend than any other format, compression ratio 3. to support image flip, smooth and other effects 4. simple and easy to use.

Description: Many images
used in the WWW are stored and transmitted after they
are compressed losslessly with the standard Graphics Interchange
Format (GIF), or Portable Network Graphics
(PNG).Well known two dimensional compression schemes,
such as JPEG-LS and CALIC, fails to yield better compression
than GIF or PNG, due to the fact that the pixel values
represent indices that point to color values in a look-up table
