I am preparing layout similar to How to create twoside book with oneside margin?
I get error in the position of caption in odd page. The location of caption in the even page is correct.
\documentclass{scrbook}
\usepackage{sidenotes}
\usepackage[demo]{graphicx}
\usepackage[paperwidth=170mm, paperheight=240mm, left=142pt, top=40pt, textwidth=280pt, marginparsep=20pt, marginparwidth=100pt, textheight=560pt, footskip=40pt
%,bindingoffset=30pt
,asymmetric
,reversemarginpar
,showframe]{geometry}
\usepackage{blindtext}
\makeatletter
\renewcommand{\@sidenotes@adjust}{%
\checkoddpage%
\ifoddpage%
\hspace{-\@sidenotes@extrawidth}%
\else%
\hspace{-\@sidenotes@extrawidth}%
\fi}
\makeatother
\begin{document}

\begin{marginfigure}
\includegraphics[width=100pt]{rectangle}
\caption{I am a figure}
\end{marginfigure}

scrbookclass, usingtwoside=semiresults in a double-sided typesetting with single-sided margins and single-sided. That is, in other words, the same thing of the optionasymmetricfor thegeometrypackage. – karlkoeller Apr 08 '14 at 05:35
