我是 TeX 和 LaTeX 的新手，我的第一個專案是一個非常雄心勃勃的專案。計劃是用來ltxkeys定義 D&D 角色扮演遊戲的資料庫條目，然後使用 LaTeX 模板來漂亮地列印角色表、怪物統計數據等。

按原樣，該文件正確呈現怪物帳篷圖像並正確放置所需的圖像和標題，但這只是因為該\includegraphics命令使用要加載的文件路徑的文字文本，而不是將其從ltxkey.如果使用第一個註解掉的\includegraphics指令而不是第二個，我會從 includegraphics 內部收到一個模糊的錯誤，表示有一個"Illegal parameter number in definition of \filename@base".
ltxkey如果我使用\gimg剛剛定義為圖像檔案路徑的而不是，則它可以工作。如果我嘗試定義在此\gimg輸入{\DnD{GoblinBoss}{image}}代碼，它會再次失敗。如果我只是列印它的值，\DnD{GoblinBoss}{image}它看起來是正確的。任何幫助，將不勝感激。

您需要定義命令，使其擴展為圖像檔案名稱。
