Tikz 图片内的 Foreach 循环 - 使用 Tikz 创建记忆卡

Question 1

这是一个使用标准 TeX “数组”方法的选项（一个例子): 使用\csname- \endcsname（或在本例中为 LaTeX 包装器\@namedef和\@nameuse）来定义带有数字的控制序列（即数组索引）。

对于您的项目，这需要三个“数组”，一个用于图像名称，一个用于卡片标题，一个用于卡片颜色。以下是界面的设置：

%%% Define "Array" interface
\makeatletter
    \newcounter{imgs}
    \setcounter{imgs}{0}
    %#1 is the image
    %#2 is the title
    %#3 is the color
    \newcommand{\addimg}[3]{%
        \stepcounter{imgs}%
        \@namedef{imgimage\theimgs}{#1}%
        \@namedef{imgtitle\theimgs}{#2}%
        \@namedef{imgcolor\theimgs}{#3}}
    \newcommand{\getimage}[1]{\expandafter\@nameuse\expandafter{imgimage#1}}%
    \newcommand{\gettitle}[1]{\expandafter\@nameuse\expandafter{imgtitle#1}}%
    \newcommand{\getcolor}[1]{\expandafter\@nameuse\expandafter{imgcolor#1}}%
\makeatother

“元素”通过命令添加到“数组”中\addimg。对于 32 张独特的卡片，如下所示：

%%% Define Cards
\addimg{example-image-A}{one}{blue}%
\addimg{example-image-B}{two}{green}%
\addimg{example-image-C}{three}{red}%
\addimg{example-image-A}{four}{yellow}%
\addimg{example-image-B}{five}{orange}%
\addimg{example-image-C}{six}{yellow}%
\addimg{example-image-A}{seven}{red}%
\addimg{example-image-B}{eight}{brown}%
\addimg{example-image-C}{nine}{green}%
\addimg{example-image-A}{ten}{blue}%
\addimg{example-image-B}{eleven}{green}%
\addimg{example-image-C}{twelve}{red}%
\addimg{example-image-A}{thirteen}{yellow}%
\addimg{example-image-B}{fourteen}{orange}%
\addimg{example-image-C}{fifteen}{yellow}%
\addimg{example-image-A}{sixteen}{red}%
\addimg{example-image-B}{seventeen}{brown}%
\addimg{example-image-C}{eighteen}{green}%
\addimg{example-image-A}{nineteen}{blue}%
\addimg{example-image-B}{twenty}{green}%
\addimg{example-image-C}{twenty one}{red}%
\addimg{example-image-A}{twenty two}{yellow}%
\addimg{example-image-B}{twenty three}{orange}%
\addimg{example-image-C}{twenty four}{yellow}%
\addimg{example-image-A}{twenty five}{red}%
\addimg{example-image-B}{twenty six}{brown}%
\addimg{example-image-C}{twenty seven}{green}%
\addimg{example-image-A}{twenty eight}{blue}%
\addimg{example-image-B}{twenty nine}{green}%
\addimg{example-image-C}{thirty}{red}%
\addimg{example-image-A}{thirty one}{yellow}%
\addimg{example-image-B}{thirty two}{orange}%

通过适当的“get”命令从各自的“数组”访问“元素”。这允许使用单个 for 循环。参数化每行的长度和图像数量：

%%% Global Setup
\newcommand\xspacing{71pt}%<== space between the images
\newcommand\yspacing{71pt}%<== vertical space between rows
\newcommand\imgperrow{4}%<== number of images per row
\tikzset{p_title/.style={text centered, minimum height=0.6cm, minimum width=5cm, font=\bfseries}}
\tikzset{p_title_line/.style={ultra thin, color=violet}}

%%% Define primary for loop
\newcommand{\forloop}[2]{%
    \foreach \x in {#1,...,#2}%<==loop for each image in the array
    {
        \edef\gonode{\noexpand\node[inner sep=0pt] (B) at (A) {\noexpand\includegraphics[width=5cm]{\getimage{\x}}};}%<==Edit to expand the file name
         \gonode%\node [inner sep=0pt] (B) at (A) {\includegraphics[width=5cm]{\getimage{\x}}};%
        \draw [black, ultra thick] ($(B.north west)$) rectangle ($(B.south east)$);%
        \node [p_title] (AA) at ($(B.north west)+(2.5,-0.30)$) {\gettitle{\x}};%
        \draw [p_title_line, color=\getcolor{\x}](AA.south west) -- (AA.south east);%
        \pgfmathparse{Mod(\x,\imgperrow)==0?1:0};%
        \ifnum\pgfmathresult>0
            \coordinate (left) at ([yshift=-\yspacing]left);
            \path let \p1=(left),\p2=(B.south) in coordinate (A) at (\x1,\y2-\yspacing);
        \else   
            \coordinate (A) at ([xshift=\xspacing]B.east);%
        \fi
    }}
%%% Define the for loop for 2 images per row on third page
\newcommand{\forlooptwo}[2]{%
    \begingroup
    \def\imgperrow{2}
    \let\originalxspacing\xspacing
    \def\xspacing{5*\originalxspacing}
    \forloop{#1}{#2}\endgroup}

和\xshift通过\yshift计算确定模数count和的\imgperrow.\forlooptwo用于第三页的四行，其中跳过了两个空格。这是通过重新定义\imgperrow和来实现的\xspacing。

然后使用以下命令创建三个页面：

\begin{document}
    \pagestyle{empty}
    %first page
    \begin{tikzpicture}[remember picture, overlay]
        \coordinate (A) at (page cs:-0.5045,0.595);
        \coordinate (left) at (A);
        \forloop{1}{24}
    \end{tikzpicture}

    %second page
    \clearpage
    \begin{tikzpicture}[remember picture, overlay]
        \coordinate (A) at (page cs:-0.5045,0.595);
        \coordinate (left) at (A);
        \forloop{25}{32}
        \forloop{1}{16}
    \end{tikzpicture}

    %third page
    \clearpage
    \begin{tikzpicture}[remember picture, overlay]
        \coordinate (A) at (page cs:-0.5045,0.595);
        \coordinate (left) at (A);
        \forloop{17}{20}
        \forlooptwo{21}{28}
        \forloop{29}{32}
    \end{tikzpicture}
\end{document}

得到：
