GifDecoder类有一部分代码存在问题，造成空引用的异常。
int save = 0;
if (transparency) {
   save = act[transIndex];
   act[transIndex] = 0; // set transparent color if specified
}
if (act == null) {
   status = STATUS_FORMAT_ERROR; // no color table defined
}

act 是不是应该先判断是否为null？
if (transparency) {
   if(acr != null){
   save = act[transIndex];
   act[transIndex] = 0; // set transparent color if specified
}
}

if (transparency) {
   if(act != null && act.length > 0 && act.length > transIndex){
   save = act[transIndex];
   act[transIndex] = 0; // set transparent color if specified
}
}
