![剥离(标题页有白线)](https://linux22.com/image/474163/%E5%89%A5%E7%A6%BB%EF%BC%88%E6%A0%87%E9%A2%98%E9%A1%B5%E6%9C%89%E7%99%BD%E7%BA%BF%EF%BC%89.png)
我需要帮助删除标题页中的条纹(如图所示)。绘制此条纹的标题页部分是:
\begin{titlepage}
\definecolor{blue}{rgb}{0.0, 0.5, 0.69}
\raggedleft
\begin{tikzpicture}[remember picture,overlay]
\node[yshift=2cm] at (current page.west)
{\begin{tikzpicture}[remember picture,overlay]
\draw[fill=blue, line width=0] (0,0)
rectangle (\paperwidth, 3cm);
\node[anchor=east, yshift=1.6cm, xshift=\paperwidth-1in, text=white]%
{\bfseries\fontsize{25}{0}\selectfont \hspace{-4cm} Matematikk};
\end{tikzpicture}};
\end{tikzpicture}
\vspace*{110pt}
{\Large \bf Støttebok - Matematikk \\ {\large (programmeringsdel med MATLAB)} \\}\par \par \par \par
\vspace*{5pt}
{\large Oppsummering med eksempler og kontrolloppgaver}\par \par
\end{titlepage}
整个代码如下,上面读取的是 titlepage1.tex 页面。
