TikZ 独立版未居中

Question

我有一张包含以下代码的图表。当我编译此代码时，左侧有一个额外的空白区域。为什么会发生这种情况？我该怎么做才能修复它？

\documentclass{standalone}

\usepackage[showframe,pass]{geometry}
\usepackage{tikz}
\usetikzlibrary{positioning}


\begin{document}

\tikzstyle{b} = [rectangle, draw, node distance=2.6cm, text width=6em, text centered, rounded corners, minimum height=8em, minimum width=6em, thick, font=\small, fill=black!10]

\begin{tikzpicture}[auto]

\node [b] (1) {block 1 \\ block 1};
\node [b, right of=1] (2) {block 2 \\ block 2};
\node [b, right of=2] (3) {block 3 \\ block 3};
\node [b, right of=3] (4) {block 4 \\ block 4};
\node [b, right of=4] (5) {block 5 \\ block 5};


\node [b, below = 2mm of 1] (6) {block 6 \\ block 6};
\node [b, below = 2mm of 2] (7) {block 7 \\ block 7};
\node [b, right of=7] (8) {block 8 \\ block 8};
\node [b, right of=8] (9) {block 9 \\ block 9};

\draw[-, thick] (1)--(2)--(3)--(4)--(5);
\draw[-, thick] (2)--(7)--(8)--(9)--(4);

\end{tikzpicture}

\end{document}

它看起来像这样：

Answer 1

这是声明后的行尾\tikzstyle。将其移到 之前\begin{document}。

顺便说一句，\tikzstyle它已被弃用，并且我将其更改为当前首选的格式。

\documentclass{standalone}

\usepackage[showframe,pass]{geometry}
\usepackage{tikz}
\usetikzlibrary{positioning}

\tikzset{
  b/.style = {
    rectangle,
    draw,
    node distance=2.6cm,
    text width=6em,
    text centered,
    rounded corners,
    minimum height=8em,
    minimum width=6em,
    thick,
    font=\small,
    fill=black!10,
  },
}

\begin{document}


\begin{tikzpicture}[auto]

\node [b] (1) {block 1 \\ block 1};
\node [b, right of=1] (2) {block 2 \\ block 2};
\node [b, right of=2] (3) {block 3 \\ block 3};
\node [b, right of=3] (4) {block 4 \\ block 4};
\node [b, right of=4] (5) {block 5 \\ block 5};


\node [b, below = 2mm of 1] (6) {block 6 \\ block 6};
\node [b, below = 2mm of 2] (7) {block 7 \\ block 7};
\node [b, right of=7] (8) {block 8 \\ block 8};
\node [b, right of=8] (9) {block 9 \\ block 9};

\draw[-, thick] (1)--(2)--(3)--(4)--(5);
\draw[-, thick] (2)--(7)--(8)--(9)--(4);

\end{tikzpicture}

\end{document}

Answer 2

使用

\documentclass[tikz]{standalone}

它将删除尾随空格。

Answer 3

摆脱导致此问题的换行符（和已弃用的\tikzstyle）的另一种可能性是将 tikz 样式移到的可选参数中\begin{tikzpicture}：

\begin{document}
\begin{tikzpicture}[
        auto,
        b/.style={rectangle, draw, node distance=2.6cm, text width=6em, text centered, rounded corners, minimum height=8em, minimum width=6em, thick, font=\small, fill=black!10},
    ]
...

Answer 4

如果您因任何原因无法更改序言，则可以通过在\begin{document}和\begin{tikzpicture}之间添加注释来忽略换行符：

\begin{document}%
%
\tikzstyle{b} = [rectangle, draw, node distance=2.6cm, text width=6em, text centered, rounded corners, minimum height=8em, minimum width=6em, thick, font=\small, fill=black!10]%
%
\begin{tikzpicture}[auto]\begin{document}%
...
