有人可以帮助解释以下示例代码吗？其中，href使用 构建时并不会在生成的 pdf 中产生超链接pdflatex。
\documentclass[landscape,a0paper,fontscale=0.285]{baposter}
\title{Summary}
\usepackage[brazilian]{babel}
\usepackage[utf8]{inputenc}
\usepackage{xcolor}
\usepackage{tabu}
\usepackage{hyperref}
\usepackage{palatino} % Use the Palatino font
\usepackage[font=small,labelfont=bf]{caption} % Required for specifying captions to tables and figures
\begin{document}
\begin{poster}
{
bgColorOne=white,
bgColorTwo=white,
}
{\bf\textsc{Bhagvad Geeta Summary}\vspace{0.5em}} % Poster title
\headerbox{Bhagvad Geeta Summary}{name=saar, column=1,span=2, row=0}{
Your world is a \href{http://www.google.com}{perception} based by your
prejudices, shaped by your fears, fueled by your ignorance.
}
\end{poster}
\end{document}
答案1
baposter通过类选项进行的字体缩放fontscale会导致链接错位。在某些页面大小和fontscale组合下，可以显示链接确实生成，并且处于活动状态，但它们与链接项无关。将纸张大小设置为a0paper和fontscale=0.9演示了此结果 - 即，链接生成，但位置错误。
此处的解决方案是设置类选项fontscale=1.0。这需要在环境中手动设置所有字体大小posterbox。这是因为设置fontscale=1.0，加上较大的纸张尺寸，会导致文本对于大型海报来说太小。
MWE 包含几个测试，演示如何使用这些posterbox键textfont来设置文本的大小posterbox和headerfont设置posterbox标题内容的大小。这些键可以全局用于所有posterboxes，也可以用于单个posterboxes。
也可以使用\fontsize{fontsize}{baselineskip}\selectfont里面的语法posterbox来放大文本。
MWE 测试使用\href、\url和创建的链接\autocite。输出显示链接与链接文本正确关联。
MWE 中有进一步的评论来解释它的作用。
我确实遇到了一件我不明白的事情（好吧，还有很多我不明白的事情LaTeX），但是当我使用语法时，除非我将文本放在里面，否则\fontsize{fontsize}{baselineskip}\selectfontbaselineskip 在 中似乎不正确。posterboxparbox
这是 MWE：
