Page Layout ⇒ Per page margins

[jaybz]

How can I achieve different margins on different pages? The reason I want to do this is that I have an align environment that I don't want to break in two. So the first page is a little crowded at the bottom but I want all the math together. Right now I use the following code. Sorry I don't know how to fill the page with math like the lipsum package does for text.

Code: Select all

\documentclass[11pt]{article}
\usepackage[top=5mm, bottom=5mm, left=15mm, right=15mm]{geometry}
\usepackage{amsmath}
\usepackage[T1]{fontenc} 
\usepackage{amssymb}
\begin{document}
\begin{align*}
y &= 2\\
x &= 4\\
\ldots \\
\ldots \\
\end{align*}

The geometry package has the \newgeometry command which allow you to define a new page layout in the middle of your document then go back to your initial layout with the \restoregeometry command

There is also \savegeometry, and \loadgeometry if you intend to reuse your new page layout.

This is a very complete package, you can find a lot in the geometry documentation.

Hope it helps

If I understand, you just want to add a bit of vertical space at the bottom of a page, so that the align environment fits on just one page. You can achieve that with \enlargethispage . For example, to add 2cm to the page height, put something like

Code: Select all

\enlargethispage{2cm}

somewhere before the align environment. The starred version of this command, in addition, shrinks the vertical space of the page as much as possible.

I tried the following both in Texmaker and Gummi (I'm on Ubuntu 11.10) but just get errors and no change in the margins of the PDF.

Code: Select all

\documentclass[11pt]{article}
\usepackage{geometry}
\geometry{hmargin={3cm,1.5cm},vmargin={2cm,3cm}}
\begin{document}
\noindent This is some text here on this line.\\
\newpage
\newgeometry{hmargin={6cm,6cm},vmargin={6cm,6cm}}
\noindent This is more text with a different page margin. \\
\restoregeometry
\end{document}

When I try to build it with Latex in Texmaker I get:

Code: Select all

Error line 7 ! Undefined control sequence.
Error line 9 ! Undefined control sequence.
BadBox line 5 Underfull \hbox (badness 10000) in paragraph at lines 5--6
BadBox line 7 Underfull \hbox (badness 10000) in paragraph at lines 7--10

Then I use:
Dvi->ps
ps->pdf

The second page of the pdf shows the following:

hmargin=6cm,6cm,vmargin=6cm,6cm This is more text with a different page margin.

You need version 5.x of the geometry package.

It's work now after installing version 5.x. Thank you all for your help.
