图片在本小节内布局

又要写新的文档了，所以就慢慢把自己常用到的命令汇总上来。

 

图片布局不要太随意，至少要在section, subsection, subsubsection 做做分割吧～

\usepackage[section]{placeins}

% Let the section can FloatBarrier
\let \oldsection \section
\renewcommand{\section}[2][]{
  \FloatBarrier
  \oldsection#1{#2}
}

% Let the subsection can FloatBarrier
\let \oldsubsection \subsection
\renewcommand{\subsection}[2][]{
  \FloatBarrier
  \oldsubsection#1{#2}
}

% Let the subsubsection can FloatBarrier
\let \oldsubsubsection \subsubsection
\renewcommand{\subsubsection}[2][]{
  \FloatBarrier
  \oldsubsubsection#1{#2}
}
