lcdfgif是哪个库,没有搜到,pngtiny/include/lcdfgif/gif.h中只有声明

unsigned char* Gif_writeMem(Gif_Stream *gfs,const Gif_CompressInfo *gcinfo,unsigned long *outsize);

from pngtiny.

哦,这个是我这边加的,原库没有这个

unsigned char *
Gif_writeMem(Gif_Stream *gfs, const Gif_CompressInfo* gcinfo, unsigned long * outsize) {
    Gif_Writer grr;
    int ok = gif_writer_init(&grr, NULL, gcinfo)&& write_gif(gfs, &grr);
    unsigned char* buf=NULL;
    if(ok) {
        buf = malloc(grr.pos);
        memcpy(buf,grr.v, grr.pos);
        memcpy(outsize,&grr.pos,sizeof(unsigned long));
    }
    gif_writer_cleanup(&grr);
    return buf;
}

from pngtiny.
