我是 Tikz 的初學者，並嘗試創建一個漂亮的主從 d 觸發器以在我的論文文件中使用。好的輸出看起來像這樣：
用來產生上圖的程式碼是這樣的：

然而，當我嘗試將 Tikz 程式碼輸入到我的論文文件中時，「主/從」框的座標似乎以某種方式偏移。這是最顯著的變化，但還有其他一些小的變化，例如鎖存器中的反相器環以及傳輸閘上的反相器環稍微偏移。這就是我論文中的輸出：
這可能是什麼原因？我在插入論文時沒有做任何縮放，應該是一樣的。這篇論文使用了一個自訂文檔類，我認為這可能會把事情搞砸。既然如此，如何才能避免這種情況呢？
答案1
正如貢薩洛·梅迪納在上面的評論中所說，錯誤是我使用嗯來定位塊。我不知道這是一個與當前字體相關的大小選項，並且由於文件具有不同的字體，因此每個頁面中的數字呈現不同。
將值變更為絕對參數，例如毫米解決了問題。
