删除标题规则和标题文本之间的间隙

Question

我想删除橙色线和蓝色框之间的白色间隙。另外，有没有一种“更干净”的方法来绘制蓝色框？

\documentclass{article}
\usepackage[margin=1in]{geometry}
\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{tikz}

\definecolor{prussianblue}{rgb}{0.0, 0.19, 0.33}

\renewcommand{\headrulewidth}{0.5mm}

\fancyhead[L]{\noindent%
\tikz{
    \draw [fill=prussianblue!80, draw=prussianblue] (0,0) rectangle (\textwidth,0.9);
    \node at (1,0.45) {\bf \color{white} Some text};
}}

\fancyhead[R]{
\tikz{
\node at (0,0) {\color{white} .};
\node at (-0.2,0) {\includegraphics[scale=0.1]{lg.png}};
}}


\pagestyle{fancy}

\usepackage{xpatch}
\xpretocmd\headrule{\color{orange}}{}{\PatchFailed}
\usepackage{blindtext}
\begin{document}
\blindtext[3]
\end{document}

如果您使用 TiKz，使用 TiKz 在矩形底部绘制线条会更简单 --- 也可以使用 fit 库来绘制矩形 - 我已将其叠加在您的图像上仅供参考 - 请看一下它是否符合您的要求 - 我认为您已经添加文本和图像 - 现在不需要 xpatch

\documentclass{article}
\usepackage[margin=1in]{geometry}
\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{tikz}
\usetikzlibrary{fit}
\usepackage{mwe}

\definecolor{prussianblue}{rgb}{0.0, 0.19, 0.33}

\renewcommand{\headrulewidth}{0.5mm}

\fancyhead[L]{\noindent%
\tikz{
    \draw [fill=prussianblue!80, draw=prussianblue] (0,0) rectangle (\textwidth,0.9);
    \node at (1,0.45) {\bf \color{white} Some text};
}}

\fancyhead[R]{
\tikz{
\node at (0,0) {\color{white} .};
\node at (-0.2,0) {\includegraphics[scale=0.1]{example-image}};
}}


\pagestyle{fancy}

\usepackage{xpatch}
\xpretocmd\headrule{\color{orange}}{}{\PatchFailed}
\usepackage{blindtext}
\begin{document}
\blindtext[3]
\begin{tikzpicture}

    \node[fit={(-10,0) (6.5,3)}, inner sep=0pt, draw=prussianblue, fill=prussianblue, thick] (rect) {};
    \draw[line width=3pt, red] (rect.south east)-- (rect.south west);
\end{tikzpicture}
\end{document}
