使用此代码，您可以创建 2x2 英寸的护照照片。如果使用 A4 纸，我们如何将照片排列成列，以便在一页上生成多张护照照片，而不会浪费相纸。只是为了好奇和好玩。

使用表格怎么样environment，精确的顺序取决于相纸的大小？

\documentclass{article}

\newcommand\PrintImage[3]{% width, height, image
  \settototalheight{\oH}{\includegraphics{#3}}%
  \settowidth{\oW}{\includegraphics{#3}}%
  \setlength{\rH}{\oH * \ratio{#1}{\oW}}
  \ifthenelse{\lengthtest{\rH < #2}}{
    \includegraphics[width=#1]{#3}%
  }{%
    \setlength{\cH}{(\rH-#2)*\ratio{\oW}{#1}}%
    \includegraphics[width=#1,clip,trim=0 \cH{} 0 0]{#3}%
  }%
