[![在此处输入图片描述][1]][1] 我想从我的 latex 文档中的一个图形中绘制两个箭头（它实际上是一张海报）。与此处的图片相同。我想使用“多列”排列下面的两幅图像。这可能很容易，但我是 Latex 的初学者，不知何故我无法做到这一点。以下是我到目前为止所做的：
\documentclass[landscape,a0paper,fontscale=0.32,margin=25mm]{baposter} % Adjust the font scale/size here
\usepackage{graphicx} % Required for including images
\graphicspath{{myfigures/}} % Directory in which figures are stored
\usepackage{amsmath} % For typesetting math
\usepackage{amssymb} % Adds new symbols to be used in math mode
\usepackage[export]{adjustbox}
\usepackage{booktabs} % Top and bottom rules for tables
\usepackage{enumitem} % Used to reduce itemize/enumerate spacing
%\usepackage{palatino} % Use the Palatino font
\usepackage[font=small,labelfont=bf]{caption} % Required for specifying captions to tables and figures
\usepackage{ragged2e} % for text alignment
\usepackage{helvet}
\renewcommand{\familydefault}{\sfdefault}
\usepackage {xcolor}\usepackage{xcolor,colortbl}
\usepackage{multicol} % Required for multiple columns
\setlength{\columnsep}{0.5em} % Slightly increase the space between columns
\setlength{\columnseprule}{0mm} % No horizontal rule between columns
\usepackage{tikz} % Required for flow chart
\usetikzlibrary{shapes,arrows} % Tikz libraries required for the flow chart in the template
\usepackage[export]{adjustbox}
\newcommand{\compresslist}{ % Define a command to reduce spacing within itemize/enumerate environments, this is used right after \begin{itemize} or \begin{enumerate}
\setlength{\itemsep}{0pt}
\setlength{\parskip}{0pt}
\setlength{\parsep}{0pt}
%\setlist{noitemsep}{format}
%\setlist[itemize]{leftmargin=*}
%\setsansfont{HelveticaNeue}
\newcommand{\squeezeup}{\vspace{-2.5mm}} % To utilize space between text and image
\renewcommand{\sfdefault}{textsf}
\setmainfont{\textsf{Sample Text 0123}}
}
\definecolor{Turquoise}{rgb}{0.145,0.6666,1} % Defines the color used for content box headers
\definecolor{uscgold}{rgb}{1,0.6,0}
\definecolor{skyblue}{rgb}{0.53, 0.81, 0.92}

boxColorOne=white, % Background color of the content boxes
textborder=roundedsmall, % Format of the border around content boxes, can be: none, bars, coils, triangles, rectangle, rounded, roundedsmall, roundedright or faded
eyecatcher=true, % Set to false for ignoring the left logo in the title and move the title left
headershape=rounded, % Specify the rounded corner in the content box headers, can be: rectangle, small-rounded, roundedright, roundedleft or rounded
headerheight=0.1 \textheight, % Height of the header
headerfont=\Large\bf\textsf, % Large, bold and sans serif font in the headers of content boxes
%textfont={\setlength{\parindent}{1.5em}}, % Uncomment for paragraph indentation
linewidth=2pt % Width of the border lines around content boxes

有人能告诉我应该把多列放在哪里，以及如何获得如上图所示的图像吗？提前谢谢。
这实际上就是我想要做的。多个箭头显示区域，并在其上方显示区域名称。

我下载了 baposter.cls，但无法编译你的文档。所以我从这里并从您的代码中添加了图形。然后我重新排列了图形，经过多次迭代后获得了
