我一直在尝试使用考试环境为考试提供出色的解决方案。我希望解决方案包含一个使用tikzpicture和的图形，pgfplots然后让文本环绕图像。我可以使用以下方法使其在没有解决方案环境的情况下工作wrapfigure：
但是一旦我使用该solutions环境，图像就会放错位置：
以下是我一直使用的代码：

\usepackage{pgfplots}
\usepackage{wrap fig}
\usepackage{lipsum}

\draw [-stealth, ultra thick, dashed, draw=blue]

答案1
从概念上来说，更简单的方法是将文本放入小页面并手动将其拆分。 \nopar结束一个段落，但不会使其看起来像段落的结尾。
优点是您可以包含方程式和其他非\baselineskip类型字段而不会弄乱一切。只需将所有内容放入迷你页面，直到您准备好放置为止\nopar。

您可以使用 中的通用代码insbox.tex来实现这一点。请注意，如果您在第一个段落后添加一个额外的段落，则insbox在环境中会以某种方式严重失败（因为它无法计算仍需要多少空间）。为此，您可以使用（但前提是您的段落在插入后开始）。不过，当您的新段落在插入过程中开始时，我没有创建任何可以工作的东西。solution\restoreinsbox
编辑：我添加了两个宏\restoreinsboxL和\restoreinsboxR，它们都带有一个可选参数。如果没有给出，它们的行为就像，但如果你给它们一个可选参数，它将被解释为额外的行数，这些行数应该很短。这样，如果第一段比插入的框短，\restoreinsbox你也可以恢复和的效果\InsertBoxL。\InsertBoxR

编辑2：下面定义了另一个包装宏实现的相当原始的草稿。它不能做很多事情，可能需要大量手动调整。然而，它在以下示例中运行得相当好。
它定义了两个宏，都只在本地范围内起作用。第一个是
\wrapcontents[<width>]{<l/r>}[<correction>]{<contents>}[<lines to skip>]
如果您指定一个<width>参数，则 width 将用于框宽度（并且材料将以垂直模式排版，类似于\parbox）。l/r您可以使用 来选择放置内容的位置，在l左边还是r右边。<correction>可以是无符号的正数，在这种情况下行数必须更短，也可以是有符号的整数（+/-），在这种情况下，它将添加到自动计算的行数中。<contents>是应该包装的内容，可以读作\vbox或\hbox。<lines to skip>是插入前段落应正常排版的行数。
第二个宏是
\restorewrap[<lines>]
如果您没有指定<lines>缩进结束的效果，如果您指定一个数字，则该效果也将用于接下来的<lines>几行。
我不知道为什么，但你必须在环境\restorewrap内使用choices，这在普通文本中不是这样的（我懒得去研究）。但由于此实现不会自动对后续段落执行任何操作，并且仅在本地范围内起作用，因此它不会影响下一个\choice。
免责声明：部分代码（插入的输出）受到了 的极大启发insbox.tex。
