我在尝试创建的海报中插入图片时遇到了问题。图片出现了，但旁边有不需要的文字。请参见图片
我正在使用命令 \includegraphics{}。此外，我有一个用 tikz 编码的图形，它根本不会出现在我的海报上。感谢您提供任何信息。
编辑：根据要求，我已经包含了我正在使用的包和代码。

Under the action of $ \SL_2(\Z) $ (or $ \Gamma_0(N) $) we can define the fundamental domain $ \F $ (or $ \F_N $) to be the set of all equivalence classes in the quotient.

LaTeX 无法处理文件名中的空格，因此使用合适的文件名应该可以解决您的问题。下面是根据您的代码编写的更简单的示例。

\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}
\providecommand{\SL}{\operatorname{SL}}
\newcommand{\F}{\mathcal{F}}
\newcommand{\Z}{\mathbb{Z}}

\DeclareMathOperator{\re}{Re}

答案2
\includegraphics{}如果不带width或选项则使用height是有风险的。
我看不到您的主屏幕，因为它被我的工作过滤器挡住了。但我猜尺寸选项可能是导致您出现问题的原因。
（我认为 PDF 中可能保存了正确的尺寸。但为了以防万一，请尝试以下方法：）
\includegraphics[width=0.4\paperwidth]{fundamental domain SL2(Z).pdf}
\includegraphics[width=0.4\paperwidth]{fundamental domain gamma0(6).pdf}
至于 tikz 图像，您能发布该部分的代码吗？目前\begin{tikzpicture}和里面什么都没有\end{tikzpicture}，所以什么都不会显示。我不知道有什么方法可以渲染 tikz 图的轮廓，但我们可以绘制一个具有所需尺寸的框。
\begin{tikzpicture}[x=5cm,y=.3cm]
\draw (0,0) rectangle (5,3);
\end{tikzpicture}
对于我来说，这显示为一个盒子。
