繼續我的上一個問題： 有沒有辦法\scalebox讓商標縮放到特定高度？我想將我在 Tikz 中建立的標誌放入我也在 Tikz 中建立的矩形中。兩者都套用章節標題。我\savebox事先使用命令保存了徽標。但現在我希望徽標與矩形具有相同的高度，並且兩者應該具有相同的原點。是否可以以height of the rectangle / \ht\logo某種方式使用像縮放因子這樣的表達式？如果徽標發生變化，這將很有幫助。這是代碼；我認為需要更改的行已標記。

如果不是，我可以以某種方式輸出徽標的大小以手動計算確切的比例嗎？我可以用 指定具體高度（以毫米為單位）嗎\scalebox？
答案1
正如egreg建議的那樣，您可以使用\resizebox，它的工作方式類似於\scalebox，只是您使用比例尺寸而不是比例因子：
\resizebox{<width dim>}{<height dim>}{contents to be scaled}
如果您想縮放到特定的寬度/高度，同時保持縱橫比。為此，您給出!依賴維度，例如在您的情況下：
\resizebox{!}{<rectangle height>}{\usebox{\logo}}
因此，只需更換\scalebox零件\resizebox{!}{15mm}{\usebox{\logo}}，縮放問題就消失了。
現在，定位存在一些問題，繪圖本身也存在一些問題。第一個細的是背景矩形，它\draw與填充選項一起使用，因此在定位徽標時我們必須處理\pgflinewidth，但由於線條和填充顏色相同，所以不需要\draw，\path改為使用線條就不會'不再被畫了。
現在，轉到包含徽標的節點。它位於中心位置，因此每當徽標大小發生變化時，您都需要相應地重新定位它。使用anchor=south west（相當於選項above right）並將節點放置at (0,0)在節點的「原點」處(0,0)。但預設情況下，該節點有一些內部 sep，我們必須將其設為 0: inner sep=0pt。此外，該節點周圍有一個 width 的底層框\pgflinewidth，這在徽標和背景框之間留下了間隙。您可以shift={(45:-\pgflinewidth)}或設定line width=0pt（這更聰明）來刪除這個小空間。所以，完成所有這些之後，繪圖應該沒問題。
