当图像向右扩展时使图像居中

Question

我有以下内容：

请注意图像位于文本上方。

如果我增加尺寸，它会继续向页面右侧和文本边缘增长，而不是在页面两侧按比例增长。

我的代码如下：

\documentclass[10pt]{article} 
\usepackage{amsmath,amsfonts,amssymb}
\usepackage{graphicx}
\graphicspath{ {./images/} }
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    filecolor=magenta,      
    urlcolor=cyan,
}
\usepackage{csquotes}
\setlength{\parskip}{\baselineskip}%
\setlength{\parindent}{0pt}%
\begin{document}
\raggedright

\begin{center}
\includegraphics[scale=0.7]{a}
\end{center}

We have $odds(D|C)$ in the numerator and $odds(D|C^c)$ in the denominator. As such, the two odds are not simply \textit{any} two odds from \textit{any} two probabilities $p_1$ and $p_2$; rather, they are 

\end{document}

如果有人能解释一下我该如何做，当我调整图片大小时，图片会按比例向页面的两侧扩展，而不是只向右侧扩展，我将不胜感激。这样一来，图片看起来会更整齐、更专业，而不会从页面的一侧突出。

\makebox[0pt][c]在 周围放置\includegraphics。这告诉排版算法图像的宽度为 0pt，并让其在两边重叠。

\usepackage{amsmath,amsfonts,amssymb}
\usepackage{graphicx}
\usepackage{hyperref}
\hypersetup{
    colorlinks=true,
    linkcolor=blue,
    filecolor=magenta,      
    urlcolor=cyan,

\usepackage{csquotes}
\setlength{\parskip}{\baselineskip}
\setlength{\parindent}{0pt}

We have $\odds(D\mid C)$ in the numerator and $\odds(D\mid C^c)$ in the denominator. As
such, the two odds are not simply \textit{any} two odds from \textit{any} two
probabilities $p_1$ and $p_2$; rather, they are
