如何对齐序列图调用中的文本？

如何对齐序列图调用中的文本？

在此处输入图片描述1. 如何对齐或左右移动序列图调用中的文本？例如，在下面的例子中，如何将第 1 条消息稍微向右移动，将第 5 条和第 6 条消息向左移动以适合一页？（我想避免使用 resizebox，因为它也会缩小字体大小）。我在这里简化了文本，shortstack 中的文本是一组相互叠加的方程式。

  1. 如果序列图超出页面（垂直方向），则会在页面底部被截断。有没有办法让序列图跨越两页？

答案1

这里的call环境是从

% from
\begin{call}[height]{caller}         {function}{callee}        {return}
% to
\begin{call}[height]{caller}[options]{function}{callee}[options]{return}
%                           ^ first new opt-arg        ^ second

两个新的可选参数都接受tikz节点选项，它们将分别应用于具有文本function和的节点return。

为了进一步缩小输出范围，我还在\tikzset{inststyle/.append style={minimum width=1.2cm}}之后添加了\begin{sequencediagram}。

您可以使用不同的值和节点选项。

对于第二个问题，没有sequencediagram使用tikzpicture，不能跨越多页。
