简短的介绍

我正在尝试为带有关联图像的多项选择题创建一个模板。我希望问题看起来像这样：

在这张图片中，我展示了我希望 Tikz 图像出现的方块，并且添加了一些线条来表明方块应该与 5 个（始终是 5 个）答案选项对齐。

我想知道是否有一些类似的包文本位置它会自动接受输入，将其置于框的中心，然后调整其大小以填充整个框。

带有 MWE 的详细描述

（请耐心听我说，我发现很难描述我的问题）

我已经使用文本位置包将 tikzpicture 放置在其所需位置。这里的问题是 tikzpicture 被渲染、裁剪（适当）到 tikzpicture 的尺寸，然后被推到左上角（textpos“锚点”所在的位置）。

我希望能够绘制具有多种不同尺寸和不同坐标的 tikzpicture，但仍然让它们位于上图所示的框内。例如，通过将圆心置于 (0,0) 并使用所有 4 个象限，可以轻松绘制圆，但对于直角三角形之类的东西，将 90 度角置于 (0,0) 并仅使用第一象限更容易。

我在这方面的尝试并不成功，因为我有点手动弄乱了一切。我手动设置锚点textpos，将其向右移动纸张宽度的 0.6 倍，并从第 5 个答案选项向上移动 3.415 厘米。之后，我画了一些 tikz 图片，并确保它们的尺寸正好适合框（恰好是 3.5 厘米 x 3.5 厘米）。

下面的代码可能有助于解释我的问题。我添加了一些尺寸信息（边距、parskip 等），因为它们是我正在进行的项目的重要组成部分。我添加了一些边界线，以表明图像的高度不应大于 5 个答案选项的高度。

我认为我想要的是让 3.5cm x 3.5cm 的盒子成为我可以将某物放入其中的东西，它就会自动将其居中并调整为适当的大小。

    \item When the size or location of the image changes in ``tikz-land'', the tikzpicture is still pushed to the top left of the red box (as expected).

        \item Choice 2

            \draw[] (0,0) node {Image};         
        \end{tikzpicture}

        \end{tikzpicture}
    \end{textblock}


\end{enumerate}

\end{document}

（注：我刚刚手动创建了数字 4 和 5 的框/图像）

从这里可以看出，更改“Tikz-land”中节点的位置不会影响其位置（它仍然附着在左上角的锚点上）。如果我更改 tikzpicture 的大小，它仍然会附着在左上角，但看起来更大。我希望它附着在框的中心并调整自身大小以填充框（但不更大）。

抱歉我说得有点多，但我觉得现在就尝试充分解释清楚比回头再讨论一切要好。提前谢谢！

编辑和附加问题

在实施@frougon 提供的解决方案后，我注意到当 Tikz 坐标超过\myheight和/或\mywidth（在本例中为 3.5）时，图片会有效地“缩小”。

如果 Tikz 图片的缩放比例无关紧要，那就太好了。我认为可以通过始终缩小 Tikz 图片以使坐标不超过 3.5 来解决这个问题（参见图 4，我将图片缩放了 3.5/10，因为 10 是最大坐标值）。

也许存在一个\MaxCoordinate我不知道的所有 Tikz 图片的定义，但我不确定。

这是我的代码和输出：

本守则的一般说明

minipage正如您所见，该环境非常有用。:-) 我在这里使用了两次：

• 具有固定的宽度和适应内容的高度：用于内部enumerate环境周围；

• 具有固定宽度和固定高度：用于框架内部，可轻松在水平和垂直方向上居中框架材料。

该\ryanjform@hrule命令允许您在中心位置调整规则参数。出于美观原因，它在两侧具有固定的字距（IMHO）。规则本身的制作方式与\leaders类似\hrulefill，但出于美观原因也被提升（请参阅height和depth参数；由 生成的规则\hrulefill将位于基线上）。因此，在我的版本中规则长度不是硬编码的：它适应规则前同一行上的文本以及封闭的小页面。

choices关于环境进行的可选扩展

默认情况下，环境会使用choices缩放从环境内容创建的框，以便缩放后的框适合框架，并且其宽度或高度等于框架的宽度或高度。此缩放过程保留了纵横比；可以使用环境的可选参数逐张图片关闭它（见下文）。还有用于更持久更改的命令；它将在下面描述。questionpicture\scaleboxautoscale=falsechoices\ryanjformsetup

此缩放过程仅考虑框尺寸，不关心其内容。这意味着内部使用的字体tikzpicture将与图片的其余部分一起缩放。如果您希望字体不缩放，则应使用autoscale=false或编写您的tikzpictures ，以便它们不需要缩放。您可以手动或使用 Ti钾Z 风格form autoscale（基于土拨鼠密码将图片边界框写入.aux，以便在下次运行 LaTeX 时对其进行适当缩放）。如 marmot写道，你会大概需要对使用该选项的 s禁用\scalebox基于 - 的缩放。最简单的方法是将其传递给环境，如下所示：tikzpictureremember pictureautoscale=falsechoices

\begin{choices}[autoscale=false]
  \begin{questionpicture}
    〈boxed material〉
  \end{questionpicture}

其中 〈boxedmaterial〉 代表您的图片，但可以是任何东西。

您必须为每个tikzpicture使用的对象form autoscale分配一个唯一标识符，该标识符不包含控制序列标记或活动字符。例如：

\begin{choices}[autoscale=false]
  \begin{questionpicture}
    \begin{tikzpicture}[form autoscale=my identifier]
       (...)
    \end{tikzpicture}
  \end{questionpicture}
  \item (...)
\end{choices}

如上所述，使用该form autoscale样式的图片会将其比例因子写入.aux文件，因此在第一次编译包含具有上述标识符的图片的文档后，您会在终端上看到此消息（LaTeX 输出）：

Automatically-scaled pictures: please recompile for picture 'my identifier'.

下一节的示例中定义的样式form autoscale autoid允许您使用计数器自动生成此类标识符，以防您不想为它们烦恼。

可能值得期待的改变

• 如果您想要框架内的内边框，只需在显示行中指定所需的宽度\setlength{\fboxsep}{0pt}%。

• 如果要autoscale=false使用默认设置（即\scalebox默认不执行基于 的缩放），只需将其替换autoscale .initial:n = { true }为autoscale .initial:n = { false }。然后要\scalebox为给定的框架图片打开基于 的自动缩放，请在环境的可选参数中传递autoscale或：autoscale=truechoices

  \begin{choices}[autoscale] ...
  

  改变默认行为的另一种方法是，例如，在您想要影响的环境\ryanjformsetup{autoscale=false}之前的某处调用。该命令遵守 TeX 的范围规则（由组定义）。它可以在前言或文档的其他地方使用。choices\ryanjformsetup

• 如果您更喜欢选择项和框架图片之间的这种对齐样式： 请执行以下操作。

  1. 代替

     \minipage{\dimexpr\linewidth-\mywidth-2\fboxrule-2\fboxsep}
     

     和：

     \minipage[t]{\dimexpr\linewidth-\mywidth-2\fboxrule-2\fboxsep}
     

  2. 代替

     \begin{minipage}[c][\myheight][c]{\mywidth}
     

     和：

     \begin{minipage}[t][\myheight][c]{\mywidth}
     

  3. 像这样 包裹\fcolorbox内部：\raisebox{\baselineskip}{...}

     \raisebox{\baselineskip}{%
       \fcolorbox{red!20}{blue!20}{%
         \begin{minipage}[t][\myheight][c]{\mywidth}
           ...
         \end{minipage}%
     }}%
     

tikzpictures 的一般定位

关于移动 s 中使用的坐标tikzpicture不会影响它们在 LaTeX 文档中的位置这一事实，这确实是正确的。Atikzpicture表现为具有宽度、高度、深度和参考点的框，并像其他框一样由 TeX 放置。如果没有特殊选项，宽度和高度通常刚好足以容纳图片内容，参考点位于左下角；但诸如和之类的选项overlay可以baseline改变这一点。你可能想读这个答案了解更多详细信息。

回复评论时使用不同行为的代码

下面是实现不同行为的代码，如下所述此评论以及以下内容（主要是：没有水平规则，不再\choice有计数器，大写选择标签，\scalebox默认情况下基于的自动缩放关闭，并使用文件.aux对环境tikzpicture内发生的所有 s进行“marmot 自动缩放” questionpicture，使用自动生成的图片标识符）：

正如评论中指出的那样，加载会修改环境parskip中项目之间的垂直间距。以下是处理此问题的一种方法：enumerateenumitem

\documentclass{article}

(...)

\makeatletter

\newtoggle{parskiploaded}
\@ifpackageloaded{parskip}
  {\toggletrue{parskiploaded}}
  {\togglefalse{parskiploaded}}

(...)

\end{document}

我们需要两个步骤，因为\@ifpackageloaded只在序言中有效。有关\iftoggle我在 中使用的替代方案etoolbox，您可能需要阅读这个答案（\iftoggle不过，还是相当不错的）。

Answer 2

我非常谨慎地提出这种方法。坦率地说，这是一种蛮力方法。但它仍然相对简单，并且保留了 OP 的大部分原始代码。对于任何行为合理且自足的 Ti 来说，这应该是有效的钾Z 图形。作为示例，我使用了本文和http://www.texample.net。

环境choices现在有一个可选参数，用于对图形使用的缩放比例进行校正（通常很小）（请参阅下面的第 12 和 14 项）。缩放比例用于更改 Ti 中的字体大小钾Z 节点仅有的。规则和界限（例如的后果\draw）未受影响。

评论中对此有很多争论，我可能忽略了一些东西。
