Beamer/Beamerposter 标题中的行距似乎不起作用

Question

我正在尝试增加标题部分的行距，我觉得我尝试了很多方法，但似乎都没有用。每当我使用时\fontsize{32}{36}，第二个参数似乎都不起作用（但第一个参数确实会改变大小）。

此外，顺便说一句，如果有人知道如何让该部分不位于海报的中心，而是直接位于大学下方，那就太好了。

这是.tex：

\documentclass[final]{beamer}
\usepackage[orientation=portrait,scale=1.4,size=a1,debug]{beamerposter}
\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\mode<presentation>{\usetheme{I6pd2}}
\usepackage{microtype}

Answer 1

尝试将标题放在minipage

\setbeamerfont{title}{series=\bfseries,size=\fontsize{100}{50}}

\begin{minipage}[b][0mm][t]{.45\paperwidth}%
    \usebeamercolor[fg]{title in headline}{%        
        \usebeamerfont{title}{%
            \normalbaselines%
            \inserttitle\par%               
        }%
    }%
\end{minipage}%
