如何在頁面左下角插入影像

Question 1

目前還不太清楚，你想要什麼。但是，這裡是如何使用textpos在一頁的四個角落列印圖像的範例（在範例中是第一個角落）：

\documentclass[14pt]{extarticle}
\usepackage{fontspec}
%\setmainfont{industry-blackitalic}% Removed, because not essential for the problem.
%\usepackage{lipsum}% Removed, because also loaded by mwe
\usepackage{mwe}
\usepackage[absolute]{textpos}
\usepackage{graphics}
\pagenumbering{gobble}

\begin{document}
\begin{textblock*}{\paperwidth}(0mm,0mm)% Upper
  \raggedright% left edge of page
  \includegraphics[page=1,width=4cm]{example-image-a4-numbered}
\end{textblock*}
\begin{textblock*}{\paperwidth}(0mm,0mm)% Upper
  \raggedleft% right edge of page
  \includegraphics[page=2,width=4cm]{example-image-a4-numbered}
\end{textblock*}
\begin{textblock*}{\paperwidth}(0mm,\paperheight)% Lower
  \raggedright% left edge of page
  \raisebox{0pt}[0pt][0pt]{\includegraphics[page=3,width=4cm]{example-image-a4-numbered}}
\end{textblock*}
\begin{textblock*}{\paperwidth}(0mm,\paperheight)% Lower
  \raggedleft% right edge of page
  \raisebox{0pt}[0pt][0pt]{\includegraphics[page=4,width=4cm]{example-image-a4-numbered}}
\end{textblock*}

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %------ II pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %-------- III pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %--------IV pagina --------------

    \lipsum[1-1]

\end{document}

如果您希望圖像位於文字區域的角落，只需刪除選項absolute並替換\paperwidth為\textwidth\paperheight\textheight。

如果你想要每個頁面都有圖像，使用eso-pic會更容易：

\documentclass[14pt]{extarticle}
\usepackage{fontspec}
%\setmainfont{industry-blackitalic}% Removed, because not essential for the problem.
%\usepackage{lipsum}% Removed, because also loaded by mwe
\usepackage{mwe}
\usepackage{eso-pic}
\usepackage{adjustbox}
\usepackage{graphics}
\pagenumbering{gobble}

\AddToShipoutPictureBG{% put the images in the background of every page
  \AtPageUpperLeft{% upper left corner of the page
    \adjincludegraphics[page=1,width=4cm,valign=T]{example-image-a4-numbered}%
  }%
  \AtPageUpperLeft{% upper
    \makebox[\paperwidth][r]{% right corner of the page
      \adjincludegraphics[page=2,width=4cm,valign=T]{example-image-a4-numbered}%
    }%
  }%
  \AtPageLowerLeft{% lower left corner of the page
    \includegraphics[page=3,width=4cm]{example-image-a4-numbered}%
  }%
  \AtPageLowerLeft{% lower
    \makebox[\paperwidth][r]{% right corner of the page
      \includegraphics[page=3,width=4cm]{example-image-a4-numbered}%
    }%
  }%
}
\begin{document}

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %------ II pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %-------- III pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %--------IV pagina --------------

    \lipsum[1-1]
\end{document}

您可以再次調整這些範例，將圖像放置在文字區域而不是紙張的邊緣。為此，再次替換\paperwidth為\textwidth並同時替換\AtPageUpperLeft為\AtTextUpperLeft和\AtPageLowerLeftby\AtTextLowerLeft。

您也可以使用此建議，使用星形變體將圖像僅添加到一頁\AddToShipoutPictureBG*。

使用最新的 LaTeX，您也可以使用出貨掛鉤：

\documentclass[14pt]{extarticle}
\usepackage{fontspec}
%\setmainfont{industry-blackitalic}% Removed, because not essential for the problem.
%\usepackage{lipsum}% Removed, because also loaded by mwe
\usepackage{mwe}
\usepackage{adjustbox}
\usepackage{graphics}
\pagenumbering{gobble}

\AddToHook{shipout/background}{% Put the images in the background of every page
  \put(0,0){% upper left corner
    \adjincludegraphics[page=1,width=4cm,valign=T]{example-image-a4-numbered}%
  }%
  \put(0,0){% upper
    \makebox[\paperwidth][r]{% right corner
      \adjincludegraphics[page=2,width=4cm,valign=T]{example-image-a4-numbered}%
    }%
  }%
  \put(0,-\pageheight){% lower left corner
    \includegraphics[page=3,width=4cm]{example-image-a4-numbered}%
  }%
  \put(0,-\pageheight){% lower
    \makebox[\paperwidth][r]{% right corner
      \includegraphics[page=4,width=4cm]{example-image-a4-numbered}%
    }%
  }%
}
\begin{document}

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %------ II pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %-------- III pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %--------IV pagina --------------

    \lipsum[1-1]
\end{document}

注意：還有許多其他方法可以將影像或其他資料放置在文件的單一或所有頁面上的固定位置。這裡顯示的可能是最簡單也是最常用的。另一種可能性，很受歡迎蒂克茲用戶，顯示在這個答案到已經作為評論連結的問題。作為相當非常規解決方案的範例，scrlayer-scrpage此處顯示了包的使用：

\documentclass[14pt]{extarticle}
\usepackage{fontspec}
%\setmainfont{industry-blackitalic}% Removed, because not essential for the problem.
%\usepackage{lipsum}% Removed, because also loaded by mwe
\usepackage{mwe}
\usepackage{adjustbox}
\usepackage{graphics}
\pagenumbering{gobble}
\usepackage{scrlayer-scrpage}
\pagestyle{plain}

\DeclareNewLayer[%
  background,%
  mode=picture,%
  page,
  contents={%
    \put(0,\paperheight){%
      \adjincludegraphics[page=1,width=4cm,valign=T]{example-image-a4-numbered}%
    }%
    \put(\paperwidth,\paperheight){%
      \makebox[0pt][r]{%
        \adjincludegraphics[page=2,width=4cm,valign=T]{example-image-a4-numbered}%
      }%
    }%
    \put(0,0){%
      \includegraphics[page=3,width=4cm]{example-image-a4-numbered}%
    }%
    \put(\paperwidth,0){%
      \makebox[0pt][r]{%
        \includegraphics[page=4,width=4cm]{example-image-a4-numbered}%
      }%
    }%
  }%
]
{cornerimages}
\AddLayersToPageStyle{plain.scrheadings}{cornerimages}

\begin{document}

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %------ II pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %-------- III pagina ------------

    \lipsum [1-1]%\\% You should never use \\ at the end of a paragraph!

\newpage %--------IV pagina --------------

    \lipsum[1-1]
\end{document}

此建議的一個很好的功能是，您可以在您想要的每個頁面的每個頁面樣式中新增和刪除新聲明的圖層。您甚至可以聲明帶有或不帶有此圖層的新頁面樣式。因此，\pagenumbering{gobble}不需要僅包含圖像的頁面：

\documentclass[14pt]{extarticle}
\usepackage{fontspec}
%\setmainfont{industry-blackitalic}% Removed, because not essential for the problem.
%\usepackage{lipsum}% Removed, because also loaded by mwe
\usepackage{mwe}
\usepackage{adjustbox}
\usepackage{graphics}
\usepackage{scrlayer-scrpage}

\DeclareNewLayer[%
  background,%
  mode=picture,%
  page,
  contents={%
    \put(0,\paperheight){%
      \adjincludegraphics[page=1,width=4cm,valign=T]{example-image-a4-numbered}%
    }%
    \put(\paperwidth,\paperheight){%
      \makebox[0pt][r]{%
        \adjincludegraphics[page=2,width=4cm,valign=T]{example-image-a4-numbered}%
      }%
    }%
    \put(0,0){%
      \includegraphics[page=3,width=4cm]{example-image-a4-numbered}%
    }%
    \put(\paperwidth,0){%
      \makebox[0pt][r]{%
        \includegraphics[page=4,width=4cm]{example-image-a4-numbered}%
      }%
    }%
  }%
]
{cornerimages}
\DeclareNewPageStyleByLayers{imagepagestyle}{cornerimages}
\pagestyle{imagepagestyle}

\begin{document}

\pagestyle{empty}

\lipsum[1-3]

\thispagestyle{imagepagestyle}% Use the images only on this page

\lipsum[4-10]

\pagestyle{imagepagestyle}% And from this page.

\lipsum

\end{document}
