小頁環境中的垂直和水平對齊

Question

右邊的圖比分配的空間寬。

如果我添加，為了顯示邊界框，

\usepackage[pass,showframe]{geometry}
\setlength{\fboxsep}{-\fboxrule}

到文檔序言並將兩個minipages 括在裡面\fbox{...}，我得到

您會看到繪圖失敗minipage，甚至會收到警告：

Overfull \hbox (33.35834pt too wide) in paragraph at lines 91--91

（行號可能不同）。

當然，這取決於文件中的文字寬度。在標準文字寬度下，如果需要比例 0.45 : 0.5，則需要縮小其中一部分或兩部分。

將繪圖縮小到 0.35，而不是程式碼中的 0.45，似乎相當令人滿意：

我使用了\begin{minipage}[b]兩者，而不是[t]，因此兩個圖例非常一致。\caption*順便說一句，不需要。

在這種情況下，提高影像似乎不太正確，但這取決於實際圖片的比例。

用肉眼衡量一下。和
