Image 以（la-）tex插入没有垂直距离的图像

我正在尝试，但我有一点距离

\documentclass{article}
\usepackage{graphicx}
\usepackage[a3paper,landscape]{geometry}
\begin{document}

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}

 \includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}

\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}\includegraphics[width=5cm, height=5cm]{1.png}


\end{document}

更改如下：

\includegraphics[width=5cm, height=5cm]{1.png}\hspace*{-1pt}\includegraphics[width=5cm, height=5cm]{1.png}\hspace*{-1pt}\includegraphics[width=5cm, height=5cm]{1.png}

谢谢你这么快的回答，但你只是在处理水平空间。这已经没有距离了。我的问题是垂直（直线）空间不是零。这很奇怪。我测试了它，得到了一个1像素的水平间距，但没有垂直间距。在fschmitt的帮助下，我记住了“*”。在行之间使用\vspace*{-1pt}，图像也会垂直对齐。
