如何將標題頁背景中的圖片置中

Question

我正在嘗試為乳膠文件建立標題頁，但一開始就失敗了，並且無法弄清楚原因。 （不過，文件的其他部分已經很好了。標題頁是唯一有問題的部分。）

（這是從Word文件“複製”設計。）

有人可以幫助我開始，例如將圖片居中放置在背景中，並製作半透明塊嗎？

舉個例子，從長遠來看，這應該是這樣的。

請注意，我現在正在關注最上面的圖片。我的目標是學習，所以我不會在頁面的其餘部分尋求幫助。

如果相關的話，我在 Windows 上使用 LuaLatex 和 TeXworks。

感謝您提供的任何幫助。

Answer 1

因此，在使用 Tikz 的建議之後，我在這裡取得了相當不錯的成績。

值得注意的是，我將它整合到了一個類別中。

可能我的設計效率也很低，歡迎大家批評指正。

最重要的問題是我的水平標題（En by i Sverige）和表格仍然位於背景圖片的中間，而我希望表格位於地址和底部徽標上方。

標題本身仍然可以浮動在圖片和表格之間，它的確切位置並不那麼重要。
