仅当 \newcommand 部分内联时才进行编译

Question

我正在尝试运行以下命令

\documentclass{article}

%% Margins Packages %%
\usepackage[margin=0cm]{geometry}

%% Graphics Packages %%
\usepackage{tikz}

%% Timeline Packages %%
\usetikzlibrary{calc,matrix}

%% Graphics Path %%
\graphicspath{{../Pictures/}}

%% Custom Commands %%
\newcommand\circularpicture[7]{
    \begin{tikzpicture}
        \node[
        circle, 
        draw=#1, 
        line width=#2, 
        inner sep=#3, 
        path picture={
            \node at (#4, #5) {
                \includegraphics[width=#6]{#7}
            };
        }] (A) {};
    \end{tikzpicture}
}

\begin{document}
    \noindent\fcolorbox{black}{black}{
        \begin{minipage}[]{0.40\textwidth}
            \textcolor{white}{
                \begin{center}
                    \fontsize{25pt}{20pt}\selectfont Name\\
                    \fontsize{15pt}{20pt}\selectfont Subject                    \\
                    \vspace*{20.0pt}
                \circularpicture{white, 1mm, 1.2cm, 0, -0.8cm, 5cm, cover-picture}
                \end{center}
            }
        \end{minipage}
    }
\end{document}

但我收到以下错误。

line 45: Paragraph ended before \@textcolor was complete. }
line 45: Argument of \circularpicture has an extra }. }
line 45: Paragraph ended before \circularpicture was complete. }
line 45: Extra }, or forgotten \endgroup. }

但是，如果我直接将命令代入文档中，它可以很好地编译。

\documentclass{article}

%% Margins Packages %%
\usepackage[margin=0cm]{geometry}

%% Graphics Packages %%
\usepackage{tikz}

%% Timeline Packages %%
\usetikzlibrary{calc,matrix}

%% Graphics Path %%
\graphicspath{{../Pictures/}}

\begin{document}
    \noindent\fcolorbox{black}{black}{
        \begin{minipage}[]{0.40\textwidth}
            \textcolor{white}{
                \begin{center}
                    \fontsize{25pt}{20pt}\selectfont Ivor Denham-Dyson\\
                    \fontsize{15pt}{20pt}\selectfont Data Science and Software
                    \\
                    \vspace*{20.0pt}
                    \begin{tikzpicture}
                        \node[
                        circle, 
                        draw=white, 
                        line width=1mm, 
                        inner sep=1.2cm, 
                        path picture={
                            \node at (0cm, -0.8cm) {
                                \includegraphics[width=5cm]{cover-picture}
                            };
                        }] (A) {};
                    \end{tikzpicture}
                \end{center}
            }
        \end{minipage}
    }
\end{document}

我对命令还不熟悉，不知道为什么？

Answer 1

当你这样做

\newcommand{\foo}[7]{...}

TeX 期望调用如下

\foo{one}{two}{three}{four}{five}{six}{seven}

并不是

\foo{one,two,three,four,five,six,seven}

这是您的代码的新版本，它也经过了简化并且进行了各种修复：

1. %字符用于掩盖会在输出中产生不需要的空格的结束行；

2. fix-cm已加载以启用任意字体大小；

3. \fontsize具有合适的基线跳跃值以更好地控制间距；

4. 与整体相比，\textcolor{white}{...}在内容开头声明白色更加简单\fcolorbox；

5. 而不是center，最好声明\centering。
