使用 tikz 设计封面时出现额外的空白页

我正在尝试设计一本带包装的书的封面tikz。以下是我的乳胶代码：

\documentclass[b5paper,11pt]{article}
\usepackage{geometry}
\usepackage{tikz}
\begin{document}
\newgeometry{top=0pt,bottom=0pt,left=0pt,right=0pt}
\thispagestyle{empty}
\setlength\parindent{0pt}
\begin{tikzpicture}[color=white,line width=.1em,font=\fontsize{90}{90}\selectfont]
\filldraw[color=blue] (0,0) rectangle (\paperwidth,\paperheight);
\draw (.05\paperwidth,0) -- (.05\paperwidth,\paperheight);
\draw (0,.1\paperheight) -- (.05\paperwidth,.1\paperheight);
\draw (0,.3\paperheight) -- (.05\paperwidth,.3\paperheight);
\draw (0,.5\paperheight) -- (.05\paperwidth,.5\paperheight);
\draw (0,.7\paperheight) -- (.05\paperwidth,.7\paperheight);
\draw (0,.9\paperheight) -- (.05\paperwidth,.9\paperheight);
\node[draw,align=center] at (.8\paperwidth,.5\paperheight) {B\\O\\O\\K};
\end{tikzpicture}
\end{document}

但是编译完 latex 代码后，除了封面之外，前面多了一个空白页。这是什么问题？

答案1

\pgflinewidth矩形的上端点位于 ， 因此矩形比纸张大(\paperwidth,\paperheight)。您可以

  1. 使用fill代替filldraw→\fill[color=blue,use as bounding box] (0,0) rectangle (\paperwidth,\paperheight);
  2. 或用于($(\paperwidth,\paperheight)+(-\pgflinewidth,-\pgflinewidth)$)矩形的构造。这需要calc库。→\filldraw[color=blue,use as bounding box] (0,0) rectangle ($(\paperwidth,\paperheight)+(-\pgflinewidth,-\pgflinewidth)$);

还请注意，我使用大蓝色矩形作为边界框。

完整代码

\documentclass[b5paper,11pt]{article}
\usepackage{geometry}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\newgeometry{top=0pt,bottom=0pt,left=0pt,right=0pt}
\thispagestyle{empty}
\setlength\parindent{0pt}
\begin{tikzpicture}[color=white,line width=.1em,font=\fontsize{90}{90}\selectfont]
\fill[color=blue,use as bounding box] (0,0) rectangle (\paperwidth,\paperheight);
%%\filldraw[color=blue,use as bounding box] (0,0) rectangle ($(\paperwidth,\paperheight)+(-\pgflinewidth,-\pgflinewidth)$);
\draw (.05\paperwidth,0) -- (.05\paperwidth,\paperheight);
\draw (0,.1\paperheight) -- (.05\paperwidth,.1\paperheight);
\draw (0,.3\paperheight) -- (.05\paperwidth,.3\paperheight);
\draw (0,.5\paperheight) -- (.05\paperwidth,.5\paperheight);
\draw (0,.7\paperheight) -- (.05\paperwidth,.7\paperheight);
\draw (0,.9\paperheight) -- (.05\paperwidth,.9\paperheight);
\node[draw,align=center] at (.8\paperwidth,.5\paperheight) {B\\O\\O\\K};
\end{tikzpicture}
\end{document}

在此处输入图片描述

简短版本：

\documentclass[b5paper,11pt]{article}
\usepackage{geometry}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\newgeometry{top=0pt,bottom=0pt,left=0pt,right=0pt}
\thispagestyle{empty}
\setlength\parindent{0pt}
\begin{tikzpicture}[color=white,line width=.1em,font=\fontsize{90}{90}\selectfont]
\filldraw[color=blue,use as bounding box] (0,0) rectangle ($(\paperwidth,\paperheight)+(-\pgflinewidth,-\pgflinewidth)$);

\foreach \x in {0.1,0.3,...,0.9}{
   \draw (0,\x\paperheight) -- (.05\paperwidth,\x\paperheight);
}
\draw (.05\paperwidth,0) -- (.05\paperwidth,\paperheight);
\node[draw,align=center] at (.8\paperwidth,.5\paperheight) {B\\O\\O\\K};
\end{tikzpicture}
\end{document}

如果你不想使用calc库，只需使用

(\paperwidth-\pgflinewidth,\paperheight-\pgflinewidth)

正如 Torbjørn T 所指出的。
