（回覆前請先閱讀：）我會的不是將第二張圖片替換為另一個範例圖像，這篇文章的重點是展示我在嘗試使用真實圖像時遇到的問題。
我有以下程式碼，其中的數字降低了以滿足幾何尺寸的上邊距參數，這解決了我大約一周前問的問題（即圖像超出了邊距邊框），但我怎麼能做到這一點像這樣的事情是自動化的，並且是在沒有指定我希望我的身材降低0.02cm的情況下完成的？

是否有一個設定adjustbox可以自動執行我需要的操作？我的範例中的圖像是這個
答案1
將範例減少很多之後：
\documentclass{article}
\usepackage{graphicx,xcolor}
\usepackage[showframe, left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}
\begin{document}
\begin{figure}[htb]
\centering
\includegraphics[page=1,width=.4\textwidth]{example-image-a4-numbered}
\caption{Test}
\end{figure}
\end{document}
我發現，那個geometry選項showframe似乎畫了文字區域的頂部框架線裡面文字區域。您也可以使用以下方法：
\documentclass{article}
\usepackage{xcolor}
\usepackage[showframe, left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}
\begin{document}
\noindent{\textcolor{red}{\raisebox{-\dp\strutbox}{\rule{.5\textwidth}{\textheight}}}}
\end{document}
這是左上角放大 5000% 的螢幕截圖：
使用 packageshowframe代替（並將框架移到背景中）：
\documentclass{article}
\usepackage{xcolor}
\usepackage[left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}
\usepackage[noframe]{showframe}
\AddToShipoutPictureBG{\ShowFramePicture}
\begin{document}
\noindent{\textcolor{red}{\raisebox{-\dp\strutbox}{\rule{.5\textwidth}{\textheight}}}}
\end{document}
顯示正確的結果：
回到你的問題：通過你的示例，但打包showframe以可視化這些區域，我得到：
所以恕我直言，這沒有任何問題，但德國人說：「Wer viel misst，misst Mist」。 （用英文來說：「如果你測量很多，你測量的就是垃圾。」）。換句話說，圖像正確地放置在文字區域的頂部，因此它遵循 的設置geometry，即使 所顯示的框架geometry另有建議。
順便一提：你的例子可以減少，而不會失去任何東西：
\documentclass{article}
\usepackage{graphicx,xcolor}
\usepackage[showframe, left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}
\begin{document}
\begin{figure}[htb]
\centering
\includegraphics[width=.4\textwidth]{04_figure.jpg}
\caption{Test}
\end{figure}
甚至：
\documentclass{article}
\usepackage{graphicx,xcolor}
\usepackage[showframe, left=1.5cm, right=1.5cm, top=1.5cm, bottom=1.5cm]{geometry}
\begin{document}
\begin{figure}[htb]
\centering
\includegraphics[page=1,width=.4\textwidth]{example-image-a4-numbered}
\caption{Test}
