显示图形的另一个问题

Question

我有我的文档的完整代码（我希望它现在是正确的）：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[demo]{graphicx}
\usepackage{placeins,listings}

\begin{document}
\lstset{language=Java, breaklines=true, basicstyle=\small, columns=fullflexible}
\tableofcontents
\newpage
\section{Title}
\subsection{Title}
Text 1
\\ Text 2:
\begin{figure}[htp]
\centering
\includegraphics[scale=0.5]{image1.jpg}
\caption{Caption 1} 
\end{figure}
\begin{figure}[htp]
\centering
\includegraphics[scale=0.5]{image2.jpg}
\caption{Caption 2}
\end{figure}
\begin{figure}[htp]
\centering
\includegraphics[scale=0.5]{image3.jpg}
\caption{Caption 3} 
\end{figure}
\begin{figure}[htp]
\centering
\includegraphics[scale=0.5]{image4.jpg}
\caption{Caption 4}
\end{figure}
\begin{figure}[htp]
\centering
\includegraphics[scale=0.5]{image5.jpg}

\begin{figure}[htp]

\includegraphics{image6.jpg}
\caption{Caption 6}
\end{figure}
\begin{figure}

\includegraphics{image7.jpg}
\caption{Caption 7}
\end{figure}
\begin{figure}
\centering
\includegraphics{image8.jpg}
\caption{Caption 8}
\end{figure}
\begin{figure}[htp]
\centering
\includegraphics{image9.jpg}
\caption{Caption 9}
\end{figure}
\end{document}

我得到了这个：第1页- 图像6在Text3之后，另一张图片（图像7，图像8，图像9）在下一页，不在图像6之后第2页。

Answer 1

由于我不知道图像的尺寸，只能graphicx使用演示模式，因此我尝试了一种解决方案，即删除图 6 和图 7 的浮动部分，并将图 8 和图 9 合并为一个浮动部分。图 8 和图 9 出现的位置当然取决于文本等。

\documentclass{article}%
\usepackage[utf8]{inputenc}
\usepackage[demo]{graphicx}
\usepackage{caption} % My addition
\usepackage{placeins}
%\usepackage{listings} % Not needed here!

\def\myscalingfactor{0.5} % Better for many images!

\begin{document}
%\lstset{language=Java, breaklines=true, basicstyle=\small, columns=fullflexible} % Not needed here
\tableofcontents
\clearpage % or \cleardoublepage if necessary is better in my point of view
