我使用的绘图程序支持 TikZ 输出。它会生成一个\begin{tikzpicture} ... \end{tikzpicture}可以包含在文档中的图像。但问题是它似乎在实际绘图周围插入了大量空白。
目前，我的方法是将图包含在“空” LaTeX 文件中，pdflatex在其上运行，然后释放pdfcrop。然后可以将生成的 PDF 包含在 TikZ 图像的位置。
但是，这根本不够干净，而且我自己也做了不少工作。因此，我想知道我是否可以指示 TikZ 帮我进行裁剪。
更新 这是一份显示该问题的最小文档；抱歉篇幅太长，机器生成的 TikZ（不幸的是）从来都不是那么简洁。我在最后添加了一个块来显示图形的边界框。

答案1
代码中添加了一些完全无用的不可见（或者说是白色）的东西。以下几行
\clip(0pt,403pt) -- (389.957pt,403pt) -- (389.957pt,99.6166pt) -- (0pt,99.6166pt) -- (0pt,403pt);
\color[rgb]{1,1,1}
\fill(3.76406pt,399.236pt) -- (380.923pt,399.236pt) -- (380.923pt,253.19pt) -- (3.76406pt,253.19pt) -- (3.76406pt,399.236pt);
\fill(53.4497pt,394.719pt) -- (374.901pt,394.719pt) -- (374.901pt,289.325pt) -- (53.4497pt,289.325pt) -- (53.4497pt,394.719pt);
绘制比实际图片更大的白色背景。TikZ 看到后会认为它是图片的一部分。只需删除/取消注释这些行即可删除大部分空白。
在第一个范围的末尾，
\color[rgb]{1,1,1}
\fill(3.76406pt,249.426pt) -- (386.193pt,249.426pt) -- (386.193pt,103.381pt) -- (3.76406pt,103.381pt) -- (3.76406pt,249.426pt);
做同样的事情。此外（在第二个结尾附近scope），
\pgftext[center, base, at={\pgfpoint{220.95pt}{106.392pt}}]{\sffamily\fontsize{9}{0}\selectfont{\textbf{ }}}
在图片下方添加一个空白节点，再次扩大边界框。
删除所有这些线会给出一个紧密的边界框。
据我所知，TikZ 无法为您进行裁剪，因为它无法知道白色的东西是否是故意的（例如，图像后面可能有深色背景，因此可以看到白色）。
答案2
\useasboundingbox <some rectangle>当然，只需在 之后插入 即可\begin{tikzpicture}。这样可以让边界框只围绕您想要的内容。查看 PGF 手册中的该命令，您就可以看到它的实际作用。
