Page Layout ⇒ Local margin for tables and images

[lancer]

Is it possible to set specific margin sizes for tables and images on the pages?
Example, my pages have 3cm left margin but for tables and images I would like to set 2cm left margin.
The best solution would be set this parameters into .cls file but how to do it? Setting this parameters into .tex file is also acceptable solution for me.
I include images using figure environment.
Thank you in advance.

It's not easy, but it's possible. Try this:

Code: Select all

\newlength{\extrawidth}%
\setlength{\extrawidth}{1cm}%
\newenvironment{wfigure}[1][tbp]{%
  \begin{figure}[#1]
    \hspace{-\extrawidth}%
    \addtolength{\textwidth}{2\extrawidth}%
    \begin{minipage}{\textwidth}%
}{\end{minipage}\end{figure}}
\newenvironment{wtable}[1][tbp]{%
  \begin{table}[#1]
    \hspace{-\extrawidth}%
    \addtolength{\textwidth}{2\extrawidth}%
    \begin{minipage}{\textwidth}%
}{\end{minipage}\end{table}}

My example gives overfull hbox warnings, but the output sounds like what you're looking for.
