为什么我的乳胶枚举给我一个很大的差距？

Question

我正在乳胶进行考试，但是由于某种原因，图像和下一个文本之间的空白空间很大。

\documentclass{article}%
\usepackage{tikz}%

\begin{document}%

\begin{enumerate}
    \item{What is the bitstring of this $4\times 4$ pixel image?\newline
        \phantom{abcdefg}\begin{tikzpicture}[scale=.7]
            \path[fill=gray] (0,0) -- (1,0) -- (1,1) -- (0,1) -- (0,0);
            \path[fill=gray] (0,2) -- (1,2) -- (1,3) -- (0,3) -- (0,2);
            \path[fill=gray] (3,2) -- (4,2) -- (4,3) -- (3,3) -- (3,2);
            \path[fill=gray] (2,2) -- (3,2) -- (3,3) -- (2,3) -- (2,2);
            \path[fill=gray] (1,2) -- (2,2) -- (2,3) -- (1,3) -- (1,2);
            \path[fill=gray] (2,1) -- (3,1) -- (3,2) -- (2,2) -- (2,1);
            \path[fill=gray] (2,3) -- (3,3) -- (3,4) -- (2,4) -- (2,3);
            \path[fill=gray] (3,3) -- (4,3) -- (4,4) -- (3,4) -- (3,3);
            \path[fill=gray] (2,0) -- (3,0) -- (3,1) -- (2,1) -- (2,0);
            \foreach \i in {0,...,4}{
                \draw [thin,black] (\i,0) -- (\i,4)  node [above] at (\i,-10){};
                \draw [thin,black] (0,\i) -- (4,\i)  node [above] at (\i,-10){};}
        \end{tikzpicture}\begin{enumerate}
            \item{$0011$ $1111$ $0010$ $1010$}
            \item{$0011$ $1111$ $0010$ $1010$}
            \item{$0011$ $1111$ $0010$ $1010$}
            \item{$0011$ $1111$ $0010$ $1010$}
            \item{$0011$ $1111$ $0010$ $1010$}
        \end{enumerate}}
\end{enumerate}

Answer 1

空间是如此之大，因为您的foreach循环中的空节点离图片很远。由于这些节点无论如何都是空的，因此您可以将它们删除并获取所需的边界框：
