 # The `easybook` document class
-Easily typesetting Chinese theses or books (v2024ha)
+Easily typesetting Chinese theses or books (v2024hb)
 
 ## Abstract
 `easybook` is a pure academic template created based on the `ctexbook` book document class. It also has the functions of `book` and `article` document class. Combined with the general framework design of the theses of many universities in China, providing multiple commands and interfaces allows users to easily customize the theses templates. Its basic macro package `easybase` can also be used with `ctex` and standard document classes.

+\section{Loading, useful packages}
+
+In order to load \ShowCode{inlinegraphicx}, simply use:
+
+\begin{DemoCode}{listing only}
+\usepackage{inlinegraphicx}
+\end{DemoCode}
+
+Loaded packages are \ShowCode{graphicx}, \ShowCode{simplekv} and \ShowCode{calc}.
+
+\section{Usage}
+
+The purpose of this package is to provide command, based on \ShowCode{\\includegraphics}, to insert graphic elements \textit{inline}, with automatic positioning and scaling.
+
+\smallskip
+
+The code determines (total)height and, if necessary, depth of letters in the current font, in order to position the image correctly :
+
+\begin{itemize}
+	\item (total)height is given by (total)height of {\setlength\fboxsep{0pt}\fbox{qH}} in the current font ;
+	\item depth is given by depth of {\setlength\fboxsep{0pt}\fbox{qH}} in the current font.
+\end{itemize}
+
+In order to adjust manually size/positioning, \ShowCode{[keys]} are available.
+
+\begin{DemoCode}{text only}
+\includegraphics[scale=3]{test_inlinegraphicx}
+\end{DemoCode}
+
+\section{The macro}
+
+\subsection{Arguments}
+
+The macro for inline insertion is \ShowCode{\\inlinegraphics}.
+
+\begin{DemoCode}{listing only}
+\inlinegraphics(*)[scale=...,strut=...]{image}
+\end{DemoCode}
+
+The starred version remove depth positioning, wheres normal version include depth.
+
+Available keys are:
+
+\begin{itemize}
+	\item \ShowCode{scale}: re-scaling of compute height (default \ShowCode{1}) ;
+	\item \ShowCode{strut}: characters for height/depth (default \ShowCode{qH}).
+\end{itemize}
+
+\subsection{Examples}
+
+\begin{DemoCode}{}
+Inline insertion, \inlinegraphics{example-image-16x10} with automatic adjustments.
+
+Inline insertion, \inlinegraphics[scale=0.75]{example-image-16x10} with automatic adjustments and scaling.
