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
