Foreach-Schleife im Tikz-Bild - Erstellen von Speicherkarten mit Tikz

Question 1

Hier ist eine Option, die den standardmäßigen TeX-„Array“-Ansatz verwendet (ein Beispiel): Verwenden Sie \csname- \endcsname(oder in diesem Fall die LaTeX-Wrapper \@namedefund \@nameuse), um Steuersequenzen mit Zahlen zu definieren (d. h. den Array-Index).

Für Ihr Projekt sind drei „Arrays“ erforderlich: eines für den Bildnamen, den Kartentitel und die Kartenfarbe. So sieht die Einrichtung der Schnittstelle aus:

%%% 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

Über den Befehl werden den „Arrays“ „Elemente“ hinzugefügt \addimg. Für die 32 einzelnen Karten würde das folgendermaßen aussehen:

%%% 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}%

Auf die "Elemente" wird über die entsprechenden "get"-Befehle aus den jeweiligen "Arrays" zugegriffen. Dadurch kann eine einzelne For-Schleife verwendet werden. Parametrisierung der Längen und Anzahl der Bilder pro Zeile:

%%% 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}

Die \xshiftund \yshiftwerden durch Berechnung bestimmtdas Modulovon countund \imgperrow. \forlooptwowird für die vier Zeilen auf der dritten Seite verwendet, in denen zwei Leerzeichen übersprungen werden. Dies wird durch die Neudefinition von \imgperrowund erreicht \xspacing.

Die drei Seiten werden dann erstellt mit:

\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 (left) at (A);
        \forloop{17}{20}
        \forlooptwo{21}{28}
        \forloop{29}{32}
    \end{tikzpicture}
\end{document}
