下午好 ！
我正在寻找一种方法来在同一页面中添加两张最大的图片。该页面将仅包含带有标题的图片：
\documentclass[notitlepage]{article}
\usepackage{amsmath, amssymb}
\usepackage{pdflscape}
\usepackage[left=0.3in,right=0.3in,top=0.3in,bottom=0.5in]{geometry}
\usepackage{colortbl}
\usepackage[margin=1cm]{caption}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage{float}
\usepackage{graphicx}
\graphicspath{{figures/}}
\usepackage{longtable}
%\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{pdfpages}
\usepackage[ ruled,vlined]{algorithm2e}
\usepackage{ifoddpage}
\usepackage{blindtext}
\usepackage{authblk}
\usepackage{listings}
\usepackage{xcolor}
\begin{document}
\FloatBarrier
\begin{figure}[h]
\begin{center}
\makebox[\textwidth]{\fbox{\includegraphics[width=\textwidth,height=\textheight,keepaspectratio]{../figures/figures2/res1.png}}}
\end{center}
\caption{Convergence performance plots of the conceived hybrid optimizer based on iterations number : part-1}
\end{figure}
\FloatBarrier
\begin{figure}[h]
\begin{center}
\makebox[\textwidth]{\fbox{\includegraphics[width=\textwidth,height=\textheight,keepaspectratio]{../figures/figures2/res2.png}}}
\end{center}
\caption{Convergence performance plots of the conceived hybrid optimizer based on iterations number : part-2}
\end{figure}
\FloatBarrier
\end{document}
所用图片如下：
感谢您的帮助 ！

该页面将支持两个几乎为其高度一半的图形textheight （因为标题需要空间）。
我简化了您的代码并使用了graphicx包中的测试图形：一个正方形和一个矩形。
由于您显然希望保持两个图形的纵横比和相同的扩展因子，因此只有一个自由度：分配给两个图形的文本高度的百分比。（示例中为 0.45，但在您的情况下可能会有所不同）。
使用该包的 [H]float将使 LaTeX 将图形保持在正确的位置。我在第一页添加了一些虚拟文本来说明它的工作原理。

答案2
一个快速测试（从 Simon 的解决方案开始）表明，如果你在后面添加一个而不是在前面添加一个，那么你可以使用[p]而不是。毕竟，这就是 [p] 浮点类型的用途。[H]\clearpage\newpage
