Floats in a setting "figures left, text right, numbering right only"

Question

I want figures on the left pages, text on the right ones and numbering on the right pages only, so I followed this: Figures on left pages, text on right ones with class book, numbering only on right pages

However some of my figures must be sideways, so that I'd like to use a sidewaysfigure environment, and some other need subfigures: how can I use floats for my figures?

Answer 1

This is a modification of this solution to "Figures on left pages, text on right ones with class book, numbering only on right pages"; see below for the complete code.

Replace the definition of \addfig by the two lines

\newcommand\addfig[1]%
  {\g@addto@macro\sos@figures
     {\vbox{\def\@captype{figure}\centering#1}\vfill}%
  }
\newcommand\addtab[1]%
  {\g@addto@macro\sos@figures
     {\vbox{\def\@captype{table}\centering#1}\vfill}%
  }

Now you don't need to load the package caption anymore. For sideways figures, load the package rotating, for sub-figures the package subfigure. In the sample code referenced above this means to replace \usepackage{booktabs,caption} by

\usepackage{booktabs,rotating,subfigure}

To add figures or tables, use

\addfig
  {...code of figure...
   \caption{...caption of figure...}%
   \label{...label of figure ...}%
  }

or

\addtab
  {...code of table...
   \caption{...caption of table...}%
   \label{...label of table ...}%
  }

For sub-figures, use

\addfig
  {\subfigure[...caption of subfigure 1]{...code of subfigure 1...}%
   \subfigure[...caption of subfigure 2]{...code of subfigure 2...}%
   \caption{...main caption...}%
  }

(and likewise \addtab for tables).

For sideways figures without sideways caption use

\addfig
  {\begin{sideways}
   ...code of sideways figure...
   \end{sideways}%
   \caption{...caption of figure...}%
  }

For sideways figures with sideways caption use

\addfig
  {\begin{sideways}
     \begin{minipage}{...width of sideways box...}
     ...code of sideways figure...
     \caption{...sideways caption of sideways figure...}%
     \end{minipage}%
   \end{sideways}%
  }

For the sake of self-containedness, here is the complete modified code.
