谢谢你的指点，不过我得到的已经是gif的像素数据了,需要做的不是对图像进行解析处理，只是需要将这些像素文件生成gif文件

Encoding (egif_lib.c) The high-level function int EGifSpew(GifFileType *GifFile) writes a complete (possibly multi-image) GIF file to the indicated file handle from in-core allocated structures created by a previous DGifSlurp() or equivalent operations. Its argument is a GIF file descriptor, which imnplicitly points to storage previously allocated by DGifSlurp(). The file is written with a GIF87 stamp unless it contains one of the four special extension blocks defined in GIF89, in which case it is written with a GIF89 stamp. EGifSpew() finishes by closing the GIF (writing a termination record to it) and deallocating the associated storage. You can write to a GIF file through a function hook. Initialize with GifFileType *EGifOpen(void *userPtr, OutputFunc writeFunc, int *ErrorCode) and see the library header file for the type of OutputFunc. There is also a set of deprecated functions for sequential I/O, described in a later section. 不知道是不是这块？ http://giflib.sourceforge.net/gif_lib.html#idm46571690348944 你研究研究给我们分享一下
