Hyperref 在 baposter 中不起作用

Question

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：

\documentclass[landscape,a0paper,fontscale=1.0]{baposter}
\usepackage{biblatex}
\usepackage{helvet}    %scaleable, sans serif font
\usepackage{microtype}
\usepackage{hyperref}
\hypersetup{%
    citebordercolor=red,
    urlbordercolor=orange,
    pdfborder=0 0 5}
\addbibresource{\jobname.bib}
\renewcommand{\rmdefault}{\sfdefault} % Default font is sans serif
