情境:這個問題是後續問題使用嵌套元素創建 TikZ 圖片的最佳實踐。符號1假如一個答案對於這個問題，\scopenode定義在哪裡。

\scopenodename=foo範圍是否轉變為節點，即可以： 透過;命名範圍通過 定位範圍at=(somewhere)；並透過 調整位置anchor=something。它們基本上很棒，因為它們可以嵌套。

然後，在如何讓 tikzexternalize 和 saveboxes 的使用相容？,CFR假如一個答案透過啟用背景和內容\scopenode的顯示來改進這些\scopenode\scopenode功能。 （Scopenode背景確實會被繪製多於否則內容。

問題：我試圖包括\scopenode在 Ti 中kZ。matrix但是，我有一些問題：

  • 使用符號 1 的解決方案，\scopenodes 位置很好，但它們的內容不會出現，因為它隱藏在填充顏色後面。
    在此輸入影像描述

  • 使用 cfr 的解決方案，可以顯示內容（並且位置很好），但\scopenode內容會變得混亂。
    在此輸入影像描述

問題：怎麼做\scopenode與Ti相容kmatrix?

微量元素
（此範例建立一個矩陣一行和兩列。在兩個單元格（A1 和 B1）中，示波器都是填充繪製的。 A（紅橙色）為南錨定，B（黃綠色）為北錨定。在每個範圍節點中，繪製一條從(0,0)到(1,1)的路徑。

進口資訊

親愛的未來的我：

供您參考，矩陣的內容僅在 hbox 中排版一次。然後將它們移動到相應的單元格中。然後將整個矩陣移動到所需的位置。第一個動作由 完成\pgf@matrix@shift@nodes@initial，第二個動作由完成\pgf@matrix@shift@nodes@secondary。它們只是應用於\pgf@shift@node節點列表。若要註冊範圍節點，您新增了以下行

\expandafter\pgf@nodecallback\expandafter{\tikz@scopenode@name@smuggle}%

所以範圍節點也被移動了。

目前，scopenode 中的所有內容都會被排版兩次。對於巢狀的範圍節點，事物的排版深度為 2倍。這真是令人沮喪。也許有人可以透過 Ti 的方式來改進這個kZ 處理矩陣。

（但是矩陣不能嵌套。你贏了！）

還有，你也變了

\global\let\tikz@fig@name\tikz@fig@name

到

\global\let\tikz@fig@name@\tikz@fig@name

以便在其他地方無法存取範圍節點的名稱。

特別是，鈦kZ 將應用於\pgf@shift@node矩陣本身。如果矩陣未命名，則最後一個範圍節點將被移動，這是不需要的。你花了兩個小時才發現這個愚蠢的錯誤。吸取教訓。

此外，您還對範圍節點的背景路徑進行了硬編碼，以便現在在範圍內容之前填入/繪製它。 （由此得名背景路徑）但計算冗長且看似多餘。我希望有人可以改進它。

儘管如此，您還是避免使用pgfonlayer.太棒了。
