如何优雅地在图形旁边添加标题（带控制参数）？

Question

我需要一个图形函数来将标题放在旁边。

图形比例应控制在“xtextwidth” 和标题比例为“ytextwidth”。到目前为止一切都很好！

该函数应控制图形与参数“1”和“2”左侧和右侧的红色垂直边框的距离。

同样，参数“3”和“4”控制字幕与绿色垂直边框的距离。

我已经尽力了，但还是没能实现。如果有人能帮我创建这个模板/序言，我将不胜感激。

这是我目前所拥有的：

\begin{figure}[!h]
\floatbox[{\capbeside\thisfloatsetup{capbesideposition={right,center},capbesidewidth=4cm,floatrowsep=quad}}]{figure}[\FBwidth]
{\caption{xyzxyz xyz xyz xyz xyz.}\label{Fig:1}}
{\centering\includegraphics[width=0.5\textwidth]{chapter-1/Figures/1.png}} 
\end{figure}

它创造了类似的东西！但它过多地基于反复试验。

编辑/更新：

如果我按照@leandriis 提供的答案，它会产生类似这样的结果：

我希望能够控制图形的左边距和标题的右边距。我该怎么做？

解决方案：

Werner 的解决方案很有效！如果您使用 \usepackage{multicol}，请查看我的评论。

Answer 1

以下是您需要的键值方法。您可以设置的键包括

• left- 左边距/间隙（默认 = 0pt）
• right- 右边距/间隙 (默认 = 0pt)
• figcapsep- 图形/图像与标题之间的水平间隙（默认 = \tabcolsep）
• figwidth- 图形/图像的宽度（如果未指定则计算）
• capwidth- 标题的宽度（若未指定则计算）
• figlabel-\label应该与\caption
• captiontoc- 中使用的可选参数\caption[<ToC>]{<text>}。

整个结构适合\linewidth。

使用以下自定义命令，\setmyimagewidth您可以设置当前图像的宽度。如果您随后将用作命令width=\myimagewidth的选项并将 用作 的选项，则标题的图像宽度将适应整体文本宽度，自动将图像的左边框与左边距对齐，将标题的右边框与右边距对齐：\includegraphicscapbesidewidth=\mycaptionwidth\thisfloatsetup
